Xtender

1 Introduction

Congratulations! You are about to install and use a device from the Xtender range. You have chosen

a high-tech device that will play a central role in energy saving for your electrical installation. The

Xtender has been designed to work as an inverter / charger with advanced functions, which can be

used in a completely modular way and guarantee the faultless functioning of your energy system.

When the Xtender is connected to a generator or network, the latter directly supplies the consumers,

and the Xtender works like a battery charger and backup device if necessary. The powerful battery

charger has an exceptional high efficiency and power factor correction (PFC) close to 1. It

guarantees excellent battery charging in all situations. The charge profile is freely configurable

according to the type of battery used or the method of usage. The charge voltage is corrected

depending on the temperature, thanks to the optional external sensor. The power of the charger is

modulated in real time dependent according to the demand of the equipment connected at the

Xtender output and the power of the energy source (network or generator). It can even temporarily

backup the source if the consumer demand exceeds the source capacity.

The Xtender continuously monitors the source to which it is connected (network or generator) and

disconnects itself immediately if the source is missing, disturbed or does not correspond to the

quality criteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the

integrated inverter. This inverter, which has an extremely robust design, benefits from STUDER

Innotec’s many years of experience and expertise in this area. It could supply any type of load

without faults, enjoying reserves of additional power that is unmatched on the market. All your

equipment will be perfectly provided with energy and protected from power outages in systems

where energy supply is unpredictable (unreliable network) or voluntarily limited or interrupted, such

as hybrid installations on remote sites or mobile installations.

The parallel and/or three-phase network operation of the Xtender offers modularity and flexibility and

enables optimum adaptation of your system to your energy requirements.

The RCC-02/03 control, display and programming centre (optional) enables optimum configuration

of the system and guarantees the operator continuous control for all important configurations in the

installation.

In order to guarantee perfect commissioning and functioning of your installation, please read this

manual carefully. It contains all the necessary information relating to the functioning of the inverters /

chargers in the Xtender series. The setting up of such a system requires special expertise and may

only be carried out by qualified personnel familiar with the applicable local regulations.

2.4 Warnings and notes

GENERAL

2.4.1

This manual is an integral part of the device and must be kept available for the operator

and installer. It must remain close to the installation so that it may be consulted at any time.

The configuration table available at the end of the manual (p. 34) must be kept up to date in the

event of modification of the configurations by the operator or installer. The person in charge of

installation and commissioning must be wholly familiar with the precautionary measures and the

local applicable regulations.

When the Xtender is running, it generates voltage that can be potentially lethal. Work on or

close to the installation must only be carried out by thoroughly trained and qualified

personnel. Do not attempt to carry out ongoing maintenance of this product yourself. The

Xtender or the generator connected to it may start up automatically under certain

predetermined conditions.

When working on the electrical installation, it is important to be certain that the source of

DC voltage coming from the battery as well as the source of AC voltage coming from a

generator or network have been disconnected from the electrical installation.

Even when the Xtender has been disconnected from the supply sources (AC and DC), a

dangerous voltage may remain at the outputs. To eliminate this risk you must switch the

Xtender OFF using the ON/OFF button (1). After 10 seconds the electronics is discharged

and intervention may take place without any danger.

All elements connected to the Xtender must comply with the applicable laws and regulations.

Persons not holding written authorisation from Studer Innotec are not permitted to proceed with any

change, modification or repairs that may be required. Only original parts may be used for authorised

modifications or replacements.

This manual contains important safety information. Read the safety and working instructions

carefully before using the Xtender. Adhere to all the warnings given on the device as well as in the

manual, by following all the instructions with regard to operation and use.

The Xtender is only designed for interior use and must under no circumstances be subjected to rain,

snow or other humid or dusty conditions.

The maximum specifications of the device shown on the type plate, as at fig. 1b, must be adhered

to.

In the event of use in motorised vehicles, the Xtender must be protected from dust, splash water

and any other humid condition. It must also be protected from vibration by installing absorbent parts.

RECAUTIONS FOR USING THE BATTERIES

2.4.2 P

Lead-acid or gel batteries produce a highly explosive gas with normal use. No source of sparks or

fire should be present in the immediate vicinity of the batteries. The batteries must be kept in a well-

ventilated place and be installed in such a way as to avoid accidental short-circuits when connecting.

STUDER Innotec

Xtender

Never try to charge frozen batteries.

When working with the batteries, a second person must be present in order to lend assistance in the

event of problems.

Sufficient fresh water and soap must be kept to hand to allow adequate and immediate washing of

the skin or eyes affected by accidental contact with the acid.

In the event of accidental contact of the eyes with acid, they must be washed carefully with cold

water for 15 minutes. Then immediately consult a doctor.

Battery acid can be neutralised with baking soda. A sufficient quantity of baking soda must be

available for this purpose.

Particular care is required when working close to the batteries with metal tools. Tools such as

screwdrivers, open-ended spanners, etc. may cause short-circuits. Consequently occurring sparks

may cause the battery to explode.

When working with the batteries, all metal jewellery such as rings, bracelet watches, earrings, etc.,

must be taken off. The current output by the batteries during a short-circuit is sufficiently powerful to

melt the metal and cause severe burns.

In all cases, the instructions of the battery manufacturer must be followed carefully.

3 Assembly and installation

3.1 Handling and moving

The weight of the Xtender is between 35 and 50kg depending upon the model. Use an appropriate

lifting method as well as help from a third party when installing the equipment.

3.2 Storage

The equipment must be stored in a dry environment at an ambient temperature of between

-20°C and 60°C. It stay in the location where it is to be used a minimum of 24 hours before being

set up.

3.3 Unpacking

When unpacking, check that the equipment has not been damaged during transportation and that

all accessories listed below are present. Any fault must be indicated immediately to the product

distributor or the contact given at the back of this manual.

Xtender

3.5 Fastening

The Xtender is a heavy unit and must be mounted to a wall designed to bear such a load.

A simple wooden panel is insufficient.

The Xtender must be installed vertically with sufficient space around it to guarantee adequate

ventilation of the device (see figs. 2a and 2b).

If the Xtender is installed in a closed cabinet this must have sufficient ventilation to guarantee an

ambient temperature that conforms to the operation of the Xtender.

Firstly, fit the mounting bracket (18) supplied with the device, using 2 Ø <6-8 mm> screws**.

Then hang the Xtender on the bracket. Fasten the unit permanently using 2 Ø <6-8 mm> screws**

on to the two notches located at the underside of the case.

**: These items are not delivered with the device.

It is imperative to ensure complete and safe fastening of the device. A device that is simply

hung may detach and cause severe damage.

In motor vehicles or when the support may be subject to strong vibrations, the Xtender must be

mounted on anti-vibration supports.

3.6 Connections

ENERAL RECOMMENDATIONS

3.6.1 G

The Xtender falls within protection class I (has a PE connection terminal). It is vital that a protective

earth is connected to the AC IN and/or AC OUT PE terminals. An additional protective earth is

located between the two fastening screws at the bottom of the unit (fig. 2b-(17)).

In all cases, the PE conductor for the equipment must at least be connected to the PE for

all equipment in protection class I upstream and downstream of the Xtender (equipotential

bonding). It is imperative that the legislation in force for the application concerned be

adhered to.

Tighten of the input (13) and output (14) terminals by means of a no. 3 screwdriver and those for the

“REMOTE ON/OFF” (7) and “AUX.CONTAC” (8) by means of a no. 1 screwdriver.

The cable sections of these terminals must conform to local regulations.

All connection cables as well as the battery cables must be mounted using cable restraints in order

to avoid any traction on the connection.

Battery cables must also be as short as possible and the section must conform with the applicable

regulations and standards. Sufficiently tighten the clamps on the “battery” inputs (fig. 4a (11) and

(12)).

EVICE CONNECTION COMPARTMENT

3.6.2 D

The unit’s connection compartment must remain permanently closed when in operation. It

is imperative to close the protection cap on the connection terminals after each intervention

in the device.

After opening, check that all sources of AC and DC voltage (batteries) have been

disconnected or put out of service.

4 Cabling

The connection of the Xtender inverter / charger is an important installation step.

It may only be carried out by qualified personnel and in accordance with the applicable local

regulations and standards. The installation must always comply with these standards.

Pay attention that connections are completely tightened and that each wire is connected at the right

place.

4.1 Choice of system

The Xtender may be used in different system types, each of which must meet the standards and

particular requirements associated with the application or site of installation. Only an appropriately

qualified installer can advise you effectively on the applicable standards with regard to the various

systems and the country concerned.

Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Please carefully

read the notes associated with these examples in the tables on p. 27 and following.

YBRID TYPE STAND ALONE SYSTEMS

4.1.1 H

The Xtender can be used as a primary supply system for grid-remote sites where a renewable

energy source (solar or hydraulic) is generally available and a generator is used as backup. In this

case, batteries are generally recharged by a supply source such as solar modules, wind power or

small hydropower systems. These supply sources must have their own voltage and/or current

regulation system and are connected directly to the battery. (Example, fig. 11)

When the energy supply is insufficient, a generator is used as a back-up energy source. This allows

the batteries to be recharged and direct supply to consumers via the Xtender transfer relay.

When the input voltage source is a low power generator (lower than the Xtender power) the

factory settings (adapted to grid-connection) must be modified according to the

“generator” column in the configuration table on p. 34.

RID CONNECTED EMERGENCY SYSTEMS

4.1.2 G

The Xtender can be used as an emergency system, also known as an uninterruptible power supply

(UPS) – enabling a reliable supply to a site connected to an unreliable network. In the event of an

interruption to the energy supply from the public network, the Xtender, connected to a battery,

substitutes the faulty source and enables a support supply to the users connected downstream.

These will be supplied as long as the energy stored in the battery allows. The battery will quickly be

recharged at the next reconnection to the public grid.

Various application examples are described in figs. 8a – 8c in appendix I.

The use of the Xtender as a UPS must be carried out by qualified personnel who have

been checked by the responsible local authorities. The diagrams in the appendix are given

for information and as a supplement. The applicable local standards and regulations must

be adhered to.

NTEGRATED MOBILE SYSTEMS

4.1.3 I

These systems are meant to be temporarily connected to the grid and ensure the supply of the

mobile system when this is disconnected from the grid. The main applications are for boats, service

STUDER Innotec

Xtender

vehicles and leisure vehicles. In these cases, two separate AC inputs are often required, one

connected to the grid and the other connected to an on-board generator. Switching between two

sources must be carried out using an automatic or manual reversing switch, conforming to the

applicable local regulations. The Xtender has a single AC input.

Various application examples are described in figs. 10a – 10b – 10c).

ULTI UNIT SYSTEMS

4.1.4 M

Whatever system is selected, it is possible to realise systems composed of several units of the same

type and the same power output. Up to three Xtenders in parallel or three extenders forming a

three-phase grid or three times two with three Xtenders in parallel forming a three-phase / parallel

grid, may be thus combined.

4.2 Earthing system

The Xtender is a protection class I unit, which is intended for cabling in a grid type TT, TN-S or TNC-

S. The earthing of the neutral conductor (E) is carried out at a sole installation point, upstream of the

RCD circuit breaker (D).

The Xtender can be operated with any earthing system. In all cases it is imperative that the

protective earth be connected in compliance with the applicable standards and regulations. The

information, notes, recommendations and diagram mentioned in this manual are subject to local

installation regulations in every case. The installer is responsible for the conformity of the installation

with the applicable local standards.

OBILE INSTALLATION OR INSTALLATION CONNECTED TO THE GRID VIA PLUG CONNECTOR

4.2.1 M

When the input of the device is connected directly to the grid via a plug, the length of the cable must

not exceed 2 m and the plug must remain accessible.

In the absence of voltage at the input, the neutral and live are interrupted, thereby guaranteeing

complete isolation and protection of the cabling upstream of the Xtender.

The earthing system downstream of the Xtender is determined by the upstream earthing system

when the grid is present. In the absence of the grid, the earthing system downstream of the inverter

is in isolated mode. The safety of the installation is guaranteed by the equipotential bonding.

The connection (link) between the neutrals (C) upstream and downstream of the Xtender is

not permitted in this configuration.

This connection type guarantees the optimal continuity for supplying the Xtender loads. The first

isolation fault will not lead to an interruption in the supply.

If the installation requires the use of a permanent isolation controller this would have to be de-

activated when the TT network is present at the Xtender input.

All sockets and protection class I devices connected downstream of the Xtender must be

properly connected to the earth (earthed socket). The cabling rules above remain valid,

including fixed installations, in all cases where the Xtender input is connected to the grid via

a plug connector.

IXED INSTALLATION

4.2.2 F

The installation may be equivalent to a mobile installation (with interrupted neutral).

In a fixed installation where the neutral is connected to the earth at a single installation point

upstream of the Xtender, it is permissible to carry out a connection of the neutrals in order to

preserve an unchanged earthing system downstream, independent of the operating mode of the

Xtender. This choice has the advantage of keeping the protection devices downstream of the

Xtender. This connection can be executed according to the examples in appendix 1, or carried out

by modifying the configuration {1486}

In this case the appearance of the first fault will lead to the installation stopping or the disconnection

of the protection devices upstream and/or downstream of the Xtender.

Safety is guaranteed by the equipotential bonding and by any RCD circuit-breakers placed

downstream.

NEUTRAL SWITCHING

PE-

In certain applications, it is desirable to keep the neutral upstream and downstream of the Xtender

separated (C) while reestablishing the earthing system (TN-S, TT or TNC-S) in the absence of

voltage at the input. This can be programmed by the configuration {1485} via the RCC-02/03

remote control. This modification must be carried out possessing technical knowledge, at the

responsibility of the installer and in conformity with the applicable regulations and standards.

This allows adherence to the requirements for an earth-neutral connection at the source.

4.3 Recommendations for dimensioning the system

IMENSIONING THE BATTERY

4.3.1 D

The battery capacity is dimensioned according to the requirements of the user – that is 5 to 10 times

its average daily consumption. The discharge depth of the battery will therefore be limited and the

service life of the battery will be extended.

On the other hand, the Xtender must have a battery capacity that is large enough to be able to take

full advantage of the performance of the equipment. The minimum capacity of the batteries

(expressed in Ah) is generally dimensioned in the following way: five times the rated power output of

the Xtender / the battery voltage. For example, the model XTH 8048 must have a battery of a

minimum capacity of 7000*5/48=730 Ah (C 10). Because of the inverter’s extreme overload capacity,

it is often recommended that this value be rounded up. An under-dimensioned battery may lead to

an accidental and undesired stopping of the Xtender in the event of high instances of use. This

stoppage will be due to a voltage that is insufficient on the battery, subject to a strong discharge

current.

The battery will be selected with regard to the greatest value resulting from the calculations set out

above.

The battery capacity determines the adjustment of the configuration {1137} “battery charge current”.

A value between 0.1 and 0.2 x C batt. [Ah] (C10) enables an optimum charge to be guaranteed.

The method proposed below is strictly indicative and in no way constitutes a guarantee of

perfect dimensioning. The installer is solely responsible for good dimensioning and

installation

IMENSIONING THE INVERTER

4.3.2 D

The inverter is dimensioned in such a way that the rated power output covers the power of all the

consumers which will be used at the same time. A dimensioning margin of 20 to 30% is

recommended to guarantee that the Xtender will work well in an ambient temperature of more than

25 °C.

IMENSIONING THE GENERATOR

4.3.3 D

The power output of the generator must be the same or more than the average daily power.

Optimally, it should be two or three times this power. Thanks to the smart boost function it is not

necessary to over-dimension the generator. Indeed, the loads those are temporarily higher than the

power of the generator will be supplied by the inverter. Ideally it should not have a power output by

phase that is less than half of the power of the Xtender(s) present at this phase.

The power available downstream of the inverter when the generator is working is the same

as the sum of the two powers.

STUDER Innotec

Xtender

IMENSIONING THE ALTERNATIVE ENERGY SOURCES

4.3.4 D

In a hybrid system, the alternative energy sources such as the solar generator, wind power and

small hydropower should, in principle, be dimensioned in such a way as to be able to cover the

average daily consumption.

4.4 Wiring diagrams

The diagrams shown in the appendix of this document are subsidiary. The applicable local

installation regulations and standards must be adhered to.

The elements referred to with an uppercase letter denote the alternate current (AC) part.

The elements referred to with a lowercase letter denote the direct current (DC) part.

4.5 Connecting the battery

Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order

to obtain an operating voltage that is correct for Xtender usage, several batteries must be connected

in series or in parallel depending on the circumstances.

In multi-unit systems, all Xtenders from the same system must be connected according to

the same battery bank.

The various cabling options are presented in figures 5a-5b (12 V), 5c-5e (24 V) and 6a to 6d (48 V) in

appendix I of this manual.

BATTERY SIDE CONNECTION

4.5.4

Before connecting the battery, carefully check the voltage and polarity of the battery using

a voltmeter.

Incorrect polarity or surge voltage may seriously damage the device.

Prepare the batteries for connection: appropriate battery clamps, protection device (f), cable in good

conditions with correctly fitted clamps.

Fasten the negative cable on to the negative pole (-) of the battery and the positive cable on the

open protection device (f).

The battery cables must be protected by one of the following measures in all cases:

- protection device (fuse) at each pole

- protection device (fuse) on the pole connected to the earth

- mechanical envelope making an accidental short-circuit impossible.

When connecting the battery, a spark may occur when connecting the second pole. This

spark is due to the load of the internal filtering capacity of the Xtender.

When connecting the battery it is necessary to check that the configuration values of the Xtender

conform to the recommendations of the battery manufacturer. Non-conforming values may be

dangerous and/or seriously damage the batteries. The default values of the battery’s charge

threshold level are shown in fig. 3a and specified in the configuration table p.34. If they prove not to

conform, it is necessary to modify them via the RCC 02/03 remote control before connecting the

voltage sources on the AC input. Studer Innotec is not responsible for default values not

corresponding with the recommendations of the manufacturer.

If the factory settings are modified, the new values must be entered on the configuration table

on p. 34 of this manual. The default values proposed by Studer Innotec are the usual values for gel

batteries (VRLA or AGM).

The calibre of the protection device (f) must be adapted to the cable section and also mounted as

close as possible to the battery.

The clamps must be carefully fixed and tightened sufficiently to guarantee minimum loss.

Insufficient tightening may cause dangerous heating at the connection point.

For safety reasons, we recommend an annual check on the tightness of all connections.

For mobile installation the connections should be checked more frequently for tightness.

The cabling and connection of the installation should only be carried out by an appropriately qualified

professional. The installation material such as cables, connectors, distribution boxes, fuses, etc.

must be adapted and must conform to the applicable laws and regulations the application under

consideration.

ARTHING THE BATTERY

4.5.5 E

One of the two battery conductors can be earthed. This may be either the positive or negative pole.

In all cases the installation must conform to the local regulations and usage or specific standards

associated with the application.

In case of earthing, the earthing conductor section must at least be equivalent to the section of the

battery conductor. The earthing of the equipment must also adhere to these regulations. In this case

the use of the additional earthing screw is recommended (fig. 2b (17)), which is located at the front

of the device between the two lower fastening screws.

ONNECTING THE CONSUMERS AT THE

4.5.6 C

OUTPUT

230 V AC

High voltages may be present on the connection terminals (13) and (14). Make sure that

the inverter is deactivated and that there is no AC or DC voltage present on the AC IN

terminals and battery terminals, before proceeding with the connection.

The 230 V consumers must be connected on the “AC OUT” (14) connection terminals with the wire

section conforming to the standards with regard to the rated current at the Xtender output (see fig.

1a). Distribution must conform to the local standards and regulations, and generally, be realised via a

distribution table.

The Xtender terminals are marked in the following way:

N = neutral, L = live

= protective earth (connected to the case of the device).

Due to the source backup function (smart boost) the current at the output of the device

may be higher than the rated current of the inverter. It is the sum of the current supplied by

the additional source and the current supplied by the inverter. In this case, the

dimensioning of the output cables will be carried out by adding the current indicated on the

protection device (H) located on the upstream of the unit, to the nominal current of the

inverter. (See fig. 1a and chap. 6.2.6 – p. 19)

If the assistance function at the source (smart boost) is not used, the calibre of the protection device

for the output (F) will be established at a maximum value equal to the rated current of the inverter, or

at the maximum value of the protection device at the input (H) if this is exceeds the rated current of

the inverter.

An additional earthing terminal (15) is present between the two fastening screws at the

bottom of the unit. It can be used instead of a connection on the input terminals of the

device, particularly when cable sections are used at the output that do not allow use of a

three-wire cable (live, earth and neutral) through the conduit glands of the connection

cables of the input and output (AC IN and AC OUT), or when the earthing of one of the

points of the battery requires a cable section greater than the the PE conductor section of

the AC IN and/or AC OUT line.

ONNECTING THE

4.5.7 C

SUPPLY SOURCES

The Xtender is intended to be supplied by alternative voltage sources such as the public grid or a

generator. Check that the rated voltage of the source corresponds to the rated voltage (34) of the

Xtender specified on the type plate (fig. 3b).

The source must be connected to the input terminals marked “AC INPUT” (13) with sufficient wire

section, depending on the power output of the source, and protected by a protection device of the

appropriate calibre. This will be at the maximum equal to the current I AC in max (35) specified on

the type plate (fig. 3b).

The terminals are marked in the following way: N = neutral, L = live, PE = protective earth

(connected to the case of the device).

IRING AUXILIARY CONTACTS

4.5.8 W

These contacts are reversing contacts that are potential-free. The admissible currents and voltages

for these contacts are 16 A: 250 VAC/24VDC or 3 A: 50 VDC max. The representation of the

contact near the terminals corresponds to the status of the contact in idle mode (light indicator (5)

off). The cabling of these auxiliary contracts depends solely on the application and cannot be

described in this manual.

The factory-set functions for these 2 auxiliary contacts are covered in the chapter 6.2.10 – p.21.

ONNECTING THE COMMUNICATIONS CABLES

4.5.9 C

The Xtender is equipped with a pair of RJ45/8 connectors that allow information transfer via a

communication bus for different consumer types which have the proprietary protocol of Studer

Innotec. In this network all parties in the network are connected in series (chain).

STUDER Innotec

Xtender

The length of the communication bus cable must not exceed 300 m.

In a system comprising a single Xtender, the connection of the RCC-02 or RCC-03 may be

conducted without stopping the Xtender (warm).

The communication bus will be used to interconnect other Xtender inverters in the case of a multi-

unit application or to connect other types of users who have the proprietary protocol of Studer

Innotec. In these cases, the installation must be switched off using the main “ON/OFF” button (1) to

connect the units via the communication bus.

The 2 switches of terminal of the communication bus, “Com. Bus" (4) both remain in

position T (terminated) except when both connectors are in use. In this case, and only in

this case, both must be placed in the O open position. If one of the two connectors is not

in use, the two termination switches (14) will be in position T.

CONNECTING THE TEMPERATURE SENSOR

4.5.10

(BTS-01)

The temperature sensor, BTS-01 is supplied with a 3 m cable fitted with RJ11/6-type plugs. It may

be connected or disconnected at any time (including when the device is in use) using the

corresponding socket (2) marked “Temp. Sens.” on the Xtender. Plug the connectors into the

socket (2) until they click in. The temperature sensor sleeve may simply be stuck onto the battery or

directly next to it. The temperature sensor will be recognised automatically and the correction made

immediately.

5 Powering up the installation

It is imperative that the closing cap for the connection compartment be installed and

screwed tight before the installation is energised. There are dangerous voltages within the

interior of the connection compartment.

The connection of the Xtender must be carried out in the order given below. Any disassembly must

be carried out in the reverse order.

1. Connecting the battery

Too high or inappropriate a battery voltage may seriously damage the Xtender. For

example, installing a 24 V battery in the Xtender 3000-12.

If the Xtender has been connected the wrong way around by accident (incorrect polarity of

the battery) it is highly likely that the protection fuse on the battery cable may melt and will

have to be replaced. If such is the case, it will be necessary to disconnect all the

connections to the Xtender including the battery. If, after replacing the fuse, the Xtender

proves not to work correctly after reconnecting the battery with the correct polarity, it will

have to be returned to your distributor for repair.

Putting the Xtender(s) in operation

using the main ON/OFF switch (1). The Xtender is

supplied and is ready for operation. If you require immediate start-up of the inverter when the

battery is powered up, the main switch (1) must be in the “ON” position and the

configuration {1111} activated.

Connecting the consumers at the output

: Activate the output protection device (F) if existing,

and/or press the ON/OFF button (41). The light indicator “AC out” (46) lights up or flashes (in

the event of an absence of consumers).

Activating the input circuit breaker(s) (H)

If an AC source (generator or electrical grid) valid in

frequency and voltage is present at the AC input, the device automatically goes into transfer

and will start to charge the batteries. The consumers at the output are therefore supplied

directly by the power source present at the input.

Your installation is now in operation. If particular configuration or adjustment is required by the

system, it is recommended to carry this out immediately. Adjustments must be made with the RCC-

02/03 remote control. Please refer to the operating instructions for this accessory.

6.2 Description of the main functions

NVERTER

6.2.1 I

The Xtender is equipped with a high-performance inverter which supplies a perfect and very precise

sine wave. Any unit designed for the 230 V/50 Hz electrical grid may connect to it without any

problem, up to the rated power out of your Xtender. The inverter is protected against overloads and

short-circuits.

Thanks to the largely over-dimensioned performance level, loads of up to three times greater than

the Xtender’s rated output can be faultlessly supplied for short periods of use, thus allowing motors

to be started up without any problem.

When the Xtender is operating the LED “ON” (43) is glowing.

When the Xtender is in inverter mode, the LED “AC out” (46) is glowing. If it flashes, the inverter is in

“load search” mode (see following chapter “Automatic load detection”).

UTOMATIC LOAD DETECTION

6.2.2 A

In order to save battery energy, the Xtender inverter stops and automatically goes into load search

when the detected load is lower than the sensitivity set by the configuration {1187}. It automatically

goes back into operation when a power consumer greater than this value demands it. The indicator

(46) flashes if the inverter is in “load search” mode, which also indicates that the AC voltage is

present at the output in an intermittent form.

The detection threshold for the absence of loads can be adjusted according to the configuration

STUDER Innotec

Xtender

range {1187} by means of the RCC-02/03 remote control. When the configuration is set to 0 the

inverter will still operate even in the absence of any consumer.

When the load search sensitivity {1187} is set to 0 in a paralleled multi-units system, the

master/slave behaviour is inhibited and all the inverter will be always functional whatever the

load is.

In standby mode the system will thus consume minimal power from the battery (see table of

technical data p. 36).

RANSFER RELAY

6.2.3 T

The Xtender can be connected to an alternative power source such as a generator or public network.

When the voltage at the entry satisfies the voltage {1199+470} and frequency {1505-1506}

parameters, the transfer relay will be activated after a delay {1528}. This delay may be

adjusted(extended) to allow a fully stabile status of the generator before transfer.

When the transfer relay is activated, the voltage present at the input of the Xtender is available at the

output for the consumers connected. At the same time the battery charger goes into operation.

When the transfer relay of the Xtender is active, the voltage at the output of the Xtender is

equivalent to that which is present at the input and cannot be influenced or improved by the

Xtender. The consumers are supplied by the source present at the “AC IN” input via the

transfer relay.

The maximum current of the transfer relay is 50 A. This means that the permanent power of the

consumers must be a maximum of 11,500 W at 230 V (18000 W for the XTH 8000-48 if smart

boost {1126} is activated). (see chap. 6.2.6 p. 19). If the battery charger is in operation, part of this

power will be used for the battery charge.

The sharing of energy between consumers and the battery charger is adjusted automatically (see

chap. 6.2.5 – p. 19). The transfer relay will be deactivated when the input voltage no longer satisfies

the configuration {1199} or {1432} min. and max. voltage and frequency at the input or when the

current limit {1107} is exceeded, if the exceeding of this limit is prohibited {1436} It then passes

immediately into inverter mode. In this case the loads are supplied exclusively by the battery via the

inverter (see chap. 6.2.6 – p. 19). This switching always takes place automatically. The presence of

increased dynamic loads (such as pneumatic angle grinders, etc.) may lead to an undesirable

opening of the transfer relay due to the weakness of the source. To this case, a delay in the opening

of the transfer relay can be adjusted with the parameter {1198}.

The transfer normally takes place without any interruption when the generator stops. It would

typically be 40 ms in the event of the immediate loss of input voltage at “AC IN”.

6.2.3.1 Fast voltage loss detection mode (fast transfer):

When the Xtender is connected to the public grid or to a generator supplying stable and clean AC

voltage, a fast voltage loss detection mode {1435} can be used. In this mode, perturbation or lack of

voltage of less than 1 millisecond can be detected, switching the unit in inverter mode immediately.

The sensitivity of this detection is adjustable with the parameter {1510}. This mode guarantee a zero

or maximum of 15 ms transfer time

This mode should not be used in presence of highly disturbed utility grid or with a low power

generator or a generator supplying a poor quality voltage

ATTERY CHARGER

6.2.4 B

The battery charger for the Xtender is completely automatic and is designed in such a way as to

guarantee an optimum charge for the majority of the lead-acid or gel batteries. Once the transfer

relay is activated, the battery charger goes into operation and the charge indicator (44) lights up.

The battery charger is designed in such a way as to guarantee charging of the battery that is as

complete as possible. The charging process is at four levels by default and guarantees optimum

charging of the batteries. The charging current is given by the configuration {1138} and can be

adjusted continuously from 0 to the nominal value with the help of the RCC-02/03.

The cycle starts with a continuous current

charge (a) adjusted by default according to

the configuration {1138}. If the ambient

temperature is increased or the ventilation

blocked, the current may be reduced and

become lower than the selected current.

Cycle de charge simplifié, sans limitation de

courant d'entrée

Once the absorption voltage {1156) is reached, the cycle passes to voltage adjustment mode (d),

known as the absorption phase, the duration of which is set by the configuration {1157}. The

minimum interval between two absorption cycles is limited by the configuration {1161).

At the expiry of the absorption time, or if the absorption current is lower than the configuration

{1159}, the voltage is set to a lower value {1140}. This phase (e) is known as the maintenance or

“floating” phase.

If the battery voltage is lower than the critical disconnection threshold {1488} operation of

the charger will be automatically prevented. Only the transfer relay is authorised to operate

in this case. The battery must then be recharged by an external source up to a voltage

higher than the critical disconnection threshold in order to allow the Xtender charger to

operate.

Given the limiting function for the input current (see the following p. 19), it is perfectly normal for the

charge current to be lower than the selected current if the limit of the AC input current {1107} is

reached (b). In this event the AC IN indicator (45) flashes.

If the “smart boost” function is activated {1126} and the power required by the consumer exceeds

the power of the source, the battery will be discharged (c) despite the presence of the grid or the

generator. In this case the LED “charge” (4) goes out. The consumers must ensure that they have

average consumption that is less than the power of the source (generator or public grid) in order to

avoid a complete discharge of the battery. These situations are set out in the figure below.

Xtender

Much more complex charge profiles or exclusion of the charger can be configured using

the RCC-03/03 remote control.

Configuration of the battery is the responsibility of the operator. Incorrect configuration that

does not correspond to the charging methods of the battery recommended by the

manufacturer may be dangerous and/or considerably diminish the battery service life. If the

factory settings are modified, it is imperative that the new values be entered in the

configuration table p. 34

IMITING THE INPUT CURRENT BY LIMITING THE CHARGER CURRENT

6.2.5 L

In order to best use the resources available at the input (depending on the generator size or the grid

output) the Xtender has a system known as power sharing.

This is a system that allows the current of the charger to be limited – from its target value {1138} to

0 – according to the current used at the output in relation to the maximum current available at the

input set by the configuration {1107}. The greater the current at the output, the more the part of the

current at the input assigned to charging the battery is reduced. If the current exceeds the limit

{1107}, the transfer relay will remain closed and the input source is likely to be overloaded bringing

the protection device (H) to open. Exceeding the limit can be forbidden by the configuration of the

parameter {1436}. If so, if the input current limit {1107} is reached, the transfer relay will be open and

the consumer will remain supplied exclusively by the inverter (battery) as long as the output current

exceeds the limit of the input current.

This system allows the sharing of power available by giving priority to the AC output (AC out) and to

the consumers who are connected to it. The charger will only use the power not utilised at the

output to ensure that the battery is charged. Once the charge current decreases by going into

“power sharing” mode, the indicator (45) flashes.

The limit value of the input current is set by the configuration {1107} and may be adjusted via the

RCC-02/03 remote control.

In the case of mobile applications the installation of an RCC-02/03 remote control is

recommended, in order to be able to adapt the value of the input current limit if necessary,

for each connection to a protected grid.

If the power usage at the output is greater than the input current value, the Xtender cannot

limit the current. This situation will then lead to the stoppage of the generator due to

overcharging or will release the upstream protection circuit for the Xtender. This major

drawback can be prevented by using the “smart boost” function described below.

HE INVERTER AS SOURCE BACKUP SMART BOOST FUNCTION

6.2.6 T

(“

”

)

The combined usage of the power sharing function and the smart boost function allows this

drawback to be overcome as mentioned above. The source backup function supplements efficiently

the charger current limiting function in order to ensure optimum protection of the fuse upstream of

the device. This system proves to be a decisive advantage particularly in all mobile systems (boats,

leisure vehicles and service vehicles) that are frequently connected to sources with a limited value

such as a portable or camping power supply. Despite a limited source, all the greater power

applications downstream of the Xtender remain functional.

When this function is activated, the battery can be fully discharged despite the presence of

the grid or the generator. The average power consumed by the user must not exceed the

power of the source, at the risk of discharging the battery.

The smart boost function is deactivated by default. To activate the function the RCC-02/03 remote

Xtender

control is required. When this function is activated {1126}, it allows the current from the battery to be

supplied to the user in order to guarantee that the current at the input of the device does not exceed

the limit set {1107}.

If the input current limit is exceeded, the transfer relay will be opened immediately, thereby

protecting the upstream protection device. If the exceeding of the input current value limit is due to a

short-circuit downstream, the transfer relay will remain activated and the protection upstream of the

Xtender (H) will be requested.

The installation cabling must take this particular function into account, which allows a current

equivalent to the sum of all power outputs in the inverter and the AC source to be available at the

output.

If you have, for example, a 5 kW (22 A) source and an Xtender of 5 kW, the power available at the

output will be 10 kW. The downstream cabling must therefore be dimensioned accordingly. In this

example, the output cable must be dimensioned to support a current of 45 A. A dimensioning table,

fig. 1a, will help you to determine the output currents that dimension the protection devices and the

cable sections to be applied.

If the Xtender is connected to a generator, this must have a power at least equal to half of

the power of the Xtender(s) to which it is connected.

NPUT CURRENT CONTROLLED BY INPUT VOLTAGE

6.2.7 I

When AC sources with variable power are connected to the Xtender's ACin, a particular parameter

setting insure a permanent availability of the nominal power at the Xtender's output thanks to the

Smartboost function. It's notably the case with "Dynawatt" 230Vac alternator coupled with variable

speed traction engines. These kinds of sources have a variable voltage according to the available

power. For this type of application, it's necessary to activate the parameter {1527}. So, the input

current limit {1107} will be regulated between zero to the programmed value, for an input voltage

whitch varies between {1309} and {1309}+{1433}

ATTERY PROTECTION

6.2.8 B

The battery is protected in all cases against deep discharge. The indicator (52) flashes once when

the battery has reached the disconnection threshold {1108} and the inverter will stop some time

after {1190}. This threshold can be dynamically corrected {1191} with an advanced algorithm tha

computes automatically the battery voltage compensation in function of the instantaneous power.

This correction may also be manually fixed {1532} by setting the low voltage disconnection at full

load {1109}. These dynamic corrections can be desactivated by stting the parameter {1191} . The

inverter will stop immediately if a critically low voltage value set by the configuration {1188} is

reached. The inverter will restart automatically when the battery voltage has reached the restarting

threshold {1110}.

This restarting threshold {1110} can be automatically readjusted if the parametewr {1194} is

activated, in order to better protect the battery against repeated cycling in an "almost empty " state

of charge. The restarting threshold is then incremented {1298} up to a maximum value {1195},

whenever the LVD (low voltage disconnection) is reached. The restarting threshold will be reset to its

initial value when the value of parameter {1307} is reached.

If the inverter is repeatedly {1304} encountering a low voltage disconnection in a short period {1404},

it will stop permanently and will only start again via an operator’s manual restart.

TENDER PROTECTION

6.2.9 X

The Xtender is protected electronically against overloads, short-circuit, overheating and reverse

current (cabling of a voltage source on AC out).

In the event of overload or short-circuit at the output, the inverter stops for some seconds and

restarts. If the inverter is repeatedly encountering this situation {1300} in a short period, it will stop

permanently and will only start again via an operator’s manual control.

If the battery voltage exceeds the value set by the configuration {1121} the inverter stops and starts

up again when the voltage is less than {1110}. If the Xtender is repeatedly encountering this situation

{1303} in a short period {1403}, it will stop permanently and will only start up again via an operator’s

manual control.

Xtender

A battery voltage greater than 1.66 x the nominal voltage may lead to significant damage or

destroy the device.

Overheating of the Xtender, Insufficient ventilation, increased ambient temperature or obstructed

ventilation may lead to overheating of certain internal components of the unit. In this case, the device

will automatically limit its power output as long as this abnormal situation persists.

The Xtender is protected from reverse polarity by means of an external fuse installed on the battery.

UXILIARY CONTACTS

6.2.10 A

The Xtender has two dry reversing contacts that are potential-free. The status of the contacts in idle

mode (deactivated) is indicated by the annotations, N.C. = normally closed and N.O. = normally

open.

Maximum contact loads: 230 Vac / 24 Vdc: 16 A or: max. 50Vdc/ 3A

These dry contacts are programmed by default for the following functions:

Contact no. 1 (AUX 1): The contact has a function of automatic star of generator (two wire). Contact

will be activated when the battery voltage is, during a given time {1247/48}/{1250/51}/{1253/54},

less than the value given by parameter {1246/49/52}. The contact will be deactivated or when the

charge cycle as reached absobtion, or when the "Aux. 1 deactivation voltage" {1255} is reached

during a pre-determinated time {1256}

The voltage of the battery is automatically compensated according to the instantaneous

battery current the same way as it is done for compensation of LVD (see chapter 6.2.8 –

p.20) if parameter {1191} is activated

Contact no. 2 (AUX2) : alarm contact by default. It is deactivated when the inverter is out of service

or is working at reduced performance, either because of manual control or if there is an operational

fault such as overload, undervoltage of the battery, overtemperature, etc.

The functions of the two auxiliary contracts can be modified and programmed variously with the help

of the RCC-02/03 control.

If the operator or installer requires different behaviour for the auxiliary contacts, they are both freely

and individually programmable depending on the battery voltage and the inverter status and the

internal clock.

The intelligent programming of the auxiliary contacts allows many applications to be considered

such as:

Automatic startup of the generator (two or three wires)

Automatic load shedding of the inverter (2 sequences)

Global or individual alarm

Automatic disconnection (load shedding) of the source

HE REAL TIME CLOCK

6.2.11 T

The Xtender has a real time clock that allows the functioning of the auxiliary contacts to be managed,

in particular. This clock must be adjusted via the use of the RCC-02/03 remote control.

EMOTE CONTROL ON OFF

6.2.12 R

The functioning of the Xtender may be interrupted by opening the connection, normally between the

two terminal points “REMOTE ON/OFF”, fig. 8a-(7). Operation will recommence when this

connection is re-established. The device is delivered with a bridge between the 2 points of this

terminal.

It is also possible to control this function according to the different variants indicated in fig. 8b. If a

variant is used, the jumpers (6) must be positioned at 1 a-b and 2 a-b.

Operating voltage: Max. 60 V eff. (I max. 30 mA)

In multi-unit configurations (see below) the interruption of operation of just one of the system’s units

by the cabled control (7) involves the immediate interruption of operation of the other units of the

system. This input can be used, for example, as an emergency stop.

increase the power output of a single or two phases. The implementation of this configuration

requires particular precautions and it must be installed and commissioned by qualified personnel

only.

When multi-unit system is commissioned, the software's version of every units will be

automatically checked and units may refuse to start in case of incompatibility. If so, an

upgrade of every units is be required with the RCC-02/03 and the last software version

available by the manufacturer. (Read the RCC-02 user's manual to perform this operation).

The inverters selected must be of the same type and the same rated power output. There is a

shared battery bank.

In these multi-unit system, the units must be interconnected via a communication bus connected to

the connectors (3) by cable (art. no. CAB-RJ45-2) of a maximum length of metres. Interrupting this

connection in a multi-unit system will lead to the stoppage – after 5 seconds – of all the units in the

system.

Various application examples are described from fig. 12 to fig. 19 of Appendix I.

It is important to read and adhere to the descriptions associated with each of the figures

mentioned above

In multi-unit system,it is not recommended to employ the manual setting {1532} of the LVD

dynamic correction.

In configurations carrying several Xtenders, each unit is controlled independently using the ON/OFF

push button (41). When the on/off control is given via the RCC-02/03 remote control, it is applied

simultaneously to all units.

HREE PHASE SYSTEM

6.3.1 T

Three Xtenders of the same type can be used and combined in order to establish a three-phase grid.

An example of cabling in three-phase is given at figs. 13.-14.

When 3 Xtenders are cabled to form a three-phase grid, the cabled phases at the input determine

the jumper position for selecting the phase (10). It is vital to determine and select the phase for each

Xtender. If the grid is not available at the input of the master unit (phase 1), all the units of the system

will switch to inverter mode. If only a single-phase source is available, it must be connected to phase

1. The other two phases will therefore be supplied by the other two working units in inverter mode.

NCREASING THE POWER AND CONNECTION IN PARALLEL

6.3.2 I

Up to three Xtenders can be cabled in parallel in order to increase the system’s rated power output.

In this configuration, all the ACin inputs of the Xtender must be cabled. One of the units functions as

master and will decide on the operation or suspension of the units in parallel according to the

consumer’s power demand. The yield of the installation is therefore still optimal.

An example of parallel connection is given in fig.12. and the comments on p. 27.

When the load search sensitivity {1187} is set to 0 in a paralleled multi-units system, the

master/slave behaviour is inhibited and all the inverter will be always functional whatever the

load is.

OMBINED SYSTEM

6.3.3 C

It is possible to combine a three-phase system with one or several phases made up of 2 or 3

Xtenders in parallel. An example of cabling is given at fig. 15.

It is therefore possible to combine up to nine Xtenders by running three Xtenders parallel in a three-

phase grid. Examples of cabling are given in figs. 16 to 18 and the comments on p. 27.

RCC-02/03 (

)

An RCC-02/03 remote display and programming unit can be optionally connected to the Xtender via

one of the two RJ45-8-type “Com. Bus” (3) connectors.

These connectors may only be used for connecting a CAN-ST compatible accessory, excluding any

other connection such as LAN, Ethernet, ISDN, etc.

The RCC-02/03 control centre is vital for modifying device configurations.

It also allows the following functions:

•

Display of function synopsis

Display of the measured operational values (current / voltage / power output, etc.)

Updating of software or implementation of customised software

Storage of inverter configuration

Updating of inverter configurations

RCC-02

RCC-03

The features of the RCC-02 and the RCC-03 are the same. They only differ in their external

appearance. The RCC-02 is designed for wall mounting, whereas the RCC-03 is designed as a

board device.

The RCC-03 model must be taken off the table to allow access to the SD card slot (during updating,

for example).

Model N°: RCC-02: Dimensions: H x W x D / / 170 x 168 x 43.5mm

RCC-03: Dimensions: H x W x D / / 130 x 120 x 42.2mm

The two remote control models are delivered with a 2 m cable by default.

Cables of specific lengths (5 m, 20 m and 50 m) can be ordered.

The article no. is as follows: CAB-RJ45-xx. The length in metres is specified as xx

Up to 3 RCC-02/03 remote controls can be connected in series on the communication bus of one

Xtender or an Xtender multi-inverter system. In a system comprising a single Xtender, the

connection of the RCC-02 or RCC-03 may be conducted without stopping the Xtender (warm).

When connecting an RCC-02/03 remote control in a multi-unit system, it is recommended that all

units in the system be stopped and that the communication bus on the device on which the

connection is being made be terminated.

The 2 switches for terminating the communication bus, “Com. Bus" (4) both remain in

position T (terminated) except when both connectors are in use. In this case, and only in

this case, both must be placed in the O (open) position. If one of the two connectors is not

in use, the two termination switches (14) will be in position T.

neutrals In a fixed installation where the neutral is connected to the earth at a

single installation point upstream of the Xtender, it is permissible to

carry out a connection of the neutrals in order to preserve an

unchanged earthing system downstream, independent of the

operating mode of the Xtender. This choice shows the advantage of

keeping the differential protection devices downstream of the

Xtender.

This connection (C) is not permitted if a socket is installed upstream

of the Xtender.

Differential circuit A protection device must be installed downstream of he source (G or

breaker

U) according to the local requirements and in compliance with the

applicable regulations and standards.

Earth-neutral

The neutral is earthed at a single point of the installation, downstream

connection bridge of the source and upstream of the protection device(s) at the default

current (DDR). When several sources are available, each source must

have an earthed neutral. If the source has to be retained with an

The Xtender has an internal current limitation the value of which is

stated on the type plate Fig. 1b (35).

The generator is dimensioned according to the requirements of the

user. Its rated current will determine the configuration adjustment
