General Information
2.1
Technology
PROTECT 1. is an Uninterruptible Power
Supply (UPS) for essential loads such as small
data centres, servers, network components,
telecommunications equipment and similar
units. It consists of:
i
♦ Mains filter with overvoltage protection (appliance
protection / class D) and mains energy backfeed
protection
♦ Rectifier section with PFC logic
(power factor correction unit)
♦ Separate battery charger with
switch mode power supply technology
♦ IGBT inverter for continuous supply of connected loads
with sinusoidal AC voltage
♦ Automatic electronic bypass (SBS)
as additional, passive redundancy
SBS = Static Bypass Switch
♦ Manual bypass for maintenance and
service purposes (with automatic
SBS activation upon actuation)
♦ Control unit
on the basis of digital signal processor technology

2.2
System Description
The UPS is connected between the public utility mains and
the loads to be protected.
The power section of the rectifier converts the mains voltage to
DC voltage for supplying the inverter. The circuit technology
used (PFC) enables sinusoidal current consumption and
therefore operation with little system disturbance. A separate,
second rectifier (charging REC set up using switch mode power
supply technology) is responsible for charging or trickle-charging
the battery connected in the intermediate circuit. The
configuration of this charging REC means the harmonic content
of the charging current for the battery is almost zero, which
increases the service life of the battery even more. The inverter
is responsible for converting the DC voltage into a sinusoidal
output voltage. A microprocessor-driven control based on a
pulse-width modulation (PWM) guarantees, in conjunction with
digital signal processor technology and extremely fast pulsating
8

IGBT power semiconductors of the inverter, a voltage system of
the highest quality and availability on the secured busbar.
In the event of mains faults (such as e.g. current failures), the
voltage continues to be supplied from the inverter to the load
without any interruption. From this point onwards, the inverter
draws its power from the battery instead of the rectifier. Since no
switching operations are necessary, there is no interruption in
the supply to the load.
The automatic electronic bypass serves to increase the reliability
of the supply further, especially in the case of individual systems.
It switches the public mains directly through to the load without
any interruption, e.g. when there is an inverter malfunction. As a
result, the automatic bypass represents an extra passive
redundancy for the load.
An integrated, manually operated bypass unit ensures an
uninterrupted supply to the connected loads in the case of
maintenance and/or service work. The internal electronic part
(with the exception of the metal-clad manual bypass) can be
disconnected via the mains input miniature circuit breakers.
The greatest possible supply reliability of connected loads is
attained by the parallel connection of up to max. three
PROTECT 1. UPS systems. The n+x technology thus
guarantees maximum reliability through up to double active
redundancy on the one hand as well as on the other hand the
possibility of increased power with simple redundancy or even
only higher UPS power without any redundancy. The relationship
between the available output power and the degree of active
redundancy can be seen in the following overview:

if necessary opened by trained and qualified
personnel. Repairs may only be carried out by
qualified customer service staff!
The output can be live, even when the UPS is not
connected to the mains supply!
16
Download from Www.Somanuals.com. All Manuals Search And Download.
For health and safety reasons, the unit must be
earthed correctly!
The PROTECT 1. may only be operated with or connected to
a three-phase power system with protective grounding using
a mains connection cable with PE conductor that has been
tested according to German standards (VDE).
Risk of burning!
The battery has powerful short-circuit currents.
Incorrect connection or isolation faults can lead to
melting of the plug connections, sparking potential
and severe burns!
The unit has a warning signal that sounds when
the battery voltage of PROTECT 1. is exhausted
or when the UPS is not working in its normal
mode (see also chapter 8 "Signalling”, page 47
and the following).
Observe the following safety instructions to
ensure permanent operational safety of and safe
work with the UPS and the battery modules
(special accessories):
♦ Do not dismantle the UPS!
(The UPS does not contain any parts that require
regular maintenance. Bear in mind that the warranty
will be invalidated if the unit is opened!)
♦ Do not install the unit in direct sunshine or in close
proximity of heaters!
♦ The unit is designed to be installed inside in heated
rooms. Never install the housing in the vicinity of water
or in an excessively damp environment!
♦ Condensation may occur if the UPS is brought from a
cold environment into the room where it is to be
installed. The UPS must be absolutely dry prior to start-
up. As a result, leave it to acclimate for at least two
hours.
♦ Never connect the mains input and the UPS output!
17
Download from Www.Somanuals.com. All Manuals Search And Download.
♦ Ensure that no fluids or foreign bodies can penetrate
the housing!
♦ Do not block the air vents of the unit! Make sure, for
example, that children do not insert any objects in the
ventilation openings!
♦ Do not connect household appliances such as
hairdryers to the UPS! Also take care when working
with motor loads. It is essential to avoid back-feeding
the inverter, e.g. if the load is intermittently operated in
regenerative mode.
Danger! Electric shocks!
Even after the mains voltage has been
disconnected, the components within the UPS
remain connected to the battery and can thus
cause electric shocks. It is therefore imperative
to disconnect the battery circuit before carrying
out any maintenance or repair work!
If it is necessary to replace the battery or carry
out maintenance work, this must be done by or
under the supervision of a specialist familiar
with batteries and the necessary safety
precautions!
Only authorized persons are allowed in the
vicinity of the batteries!
When replacing the batteries, the following must be observed:
Only ever use identical, maintenance-free sealed lead
batteries with the same data as the original batteries.
Danger! Explosive!
Never throw batteries into open fire.
Never open or damage batteries. (Electrolyte
may leak out and damage skin and eyes. It may
be toxic!)
Batteries can cause electric shocks and high
short-circuit currents.

Therefore, take the following safety precautions when working
with batteries:
♦ Take off watches, rings and other metallic objects!
♦ Only use tools with insulated handles!
Avoid using multiple outlet adapters with a
central on/off switch as protection against
uncontrolled load switch-off as well as for
avoiding peak inrush currents.
i
Switch OFF the UPS using its main switch if you do not intend
to use it for some time. PROTECT 1. must be switched off
every evening if the electricity supply in your company is
switched off every night. Otherwise, the battery will be
discharged. Frequent and exhaustive discharging of the
battery leads to a shorter service life of the battery and should
therefore be avoided!
For personal safety reasons, never switch on
the main switch when the mains connector of
PROTECT 1. is disconnected!

4.2
Transport to Installation Site
The PROTECT 1. is equipped with transport rolls for easy
transport to the intended installation site. It is recommended
to install the UPS where:
♦ The connection work can be conveniently carried out;
♦ There is enough space for proper operation and, if
necessary, for periodic and extraordinary maintenance
work; in this regard, the connection cables should be
long enough to move the UPS (to open the UPS if
necessary) without having to switch it off.
♦ The use of an external manual bypass is recommended
♦ The UPS is protected against external atmospheric
influences;
♦ The humidity and the ambient temperature are within
the limits;
♦ The fire protection standards are observed.
The battery service life strongly depends on the ambient
temperature. Ambient temperatures between+15° and +25°C
are optimum.
Attention!
Only transport the PROTECT 1. in an upright
position! Never tilt or cant it; avoid displacing
the centre of gravity!
Make sure that no magnetic storage media are stored and/or
operated close to PROTECT 1.

4.3
Set-Up
Note the following points when setting up the UPS system
and its external battery units (special accessories):
♦ The contact surface must be smooth and level. It must
also be sufficiently strong and sturdy to avoid vibration
and shocks.
♦ Make sure that the mounting is able to support the
weight, especially in conjunction with external battery
units (special accessories).
♦ Set up the units so that adequate air circulation is
assured. There must be at least 200 mm clearance
behind the rear fans for ventilation purposes. Do not
block the intake openings on the front and, if present,
on the side of the unit. There must be a gap of at least
50 mm here.
♦ External battery units must be placed on the side of the
UPS system. To ensure the greatest possible
mechanical stability, do not place the external battery
unit(s) above or below the UPS system.
♦ Avoid extreme temperatures! We recommend an
ambient temperature from 15°C to 25°C in order to
maximize the service life of the batteries. Do not
expose the units to direct sunlight or operate them
close to other heat sources such as radiators.
♦ Protect the units against external effects (in particular
moisture and dust). In this regard, please also refer to
the instructions in chapter 3, page 15 in these operating
instructions.
If you transport the unit from a cold room into a warm one, or
if the room temperature suddenly drops, then condensation
may form inside the unit. To avoid any damage due to
condensation, let the unit acclimate for 2 hours before you
switch it on.

Electrical Connection
Caution
Prior to commencing work, ensure that the
connection cables are de-energised and that it
is not possible to activate the power supply.
In order to avoid deformation of the supporting
rail and to protect the base of the connection
terminal against torsional forces, it is advisable
to hold the cable in position when tightening the
clamping screw.
i
The protective measure of earth connection serves to prevent
excessive touch voltage on freely accessible metal parts. The
PROTECT 1. is earthed by the provided earthing bolts (
/
PE). Prior to start-up, it must be ensured that the PROTECT 1. is
earthed in accordance with valid regulations, e.g. VDE 0100.
Before the connection work is carried out, check that:
♦ The values of the nominal voltage (input voltage) and
frequency match those on the nameplate of the UPS.
♦ The earth connection matches the prescribed IEC
standards or the local regulations,
♦ The UPS is connected to the electrical mains via a
separate supply line equipped with fuses on the supply-
side MI distribution.
♦ The power fuse in the MI distribution has the same or
higher value as the one indicated on the nameplate of
the UPS system.

connected as follows:
♦ Remove terminal cover (retain the four screws).
♦ Insert the cables to be connected into the terminal
space of the PROTECT 1. from the rear.
♦ Connect the wires of the supply lines to the
corresponding terminal block. Connect the PE to the
terminal block of the PROTECT 1.100 or to the strain
relief unit of the PROTECT 1.150 or 1.200.
♦ Fasten the supplied cable clamping unit (no. 9, p. 26/27)
with the previously removed screws.
In the case of the PROTECT 1.150 and 1.200, also
remove the lateral earthing bolts beforehand and use them
to fasten the cable clamping unit as well.
♦ Check to ensure that the cables are secured correctly
and tighten the fixing bolts if necessary.
♦ Remove any cable debris, tools, bolts, etc. from the
connection panel.

Mains Connection
5.4.1
Preparation for the three-phase mains connection
Before connection work is performed on the UPS, make sure
that:
♦ The values of the nominal voltage (supply) and
frequency match those on the nameplate of the UPS.
♦ The earth connection matches the prescribed IEC
standards or the local regulations,
♦ The UPS can be connected to the electrical mains via a
separate supply line equipped with fuses in the supply-
side MI distribution.
♦ Back-up fuses or line safety switches are used that
correspond to the values listed in chapter 5.2.2.
♦ The connection cable from the back-up fuse to the UPS
is configured with a minimum cross-section acc. to
chapter 5.2.2 “Connection Cross-Sections and Fuse
Protection”.
The UPS can be live, and the voltage can be
dangerous. The unit may only be installed and
if necessary opened by trained and qualified
personnel. Repairs may only be carried out by
qualified customer service staff!
5.4.2
Connection of the Three-Phase Input Mains Voltage
In order to ensure the safety of personnel during installation
work, make sure that the connections are made under the
following conditions:
♦ No mains voltage present.
♦ The loads are switched off.
♦ The PROTECT 1. is switched off (display completely
blank).
To disconnect the PROTECT 1, carry out the following steps
as well:
31

Only remove the cable if you want to use the UPS
in parallel operation with further PROTECT 1. units
of the same type (see also chapter 9).
5.4.3
Preparation of the Output Cabling
Before you connect the loads to the UPS, the nominal output
listed on the nameplate must be greater than or equal to the
sum of the load power outputs.
The output of the PROTECT 1. should supply further separate
circuits in a subdistribution. Make sure that the fuse protection is
selectively designed (see also chapter 5.2.2).
For the connection between the PROTECT 1. and the
subdistribution, cable cross-sections acc. to the table
“Connection Cross-Sections and Fuse Protection” on p. 30
must be used. In the subdistribution, note at least the
following information:
♦ Maximum permissible total load
♦ Maximum permissible load of the individual load circuits
In the case of a common distribution cabinet
(circuits with mains as well as UPS voltage), label
each circuit with the respective supply (mains or
UPS).

later, whereby the UPS is now in normal
operating mode. When the mains supply is intact
(mains within tolerance), the "Line" LED also
lights up.

Once you have connected the UPS to a suitable mains
connection, you can start operation using the UPS main
switch. Normally, the UPS operates continuously. The UPS
now supplies the output with voltage, which is signalled by the
mains symbol (Line LED) and the inverter symbol (Inverter
LED) being lit.
This operating mode, generally referred to as “online” mode,
ensures the greatest protection, in particular when there are
mains fluctuations and mains failures, because the loads are

continuously supplied with reliable and “clean” voltage with no
interruptions in this operating mode.

The mains is not within the required tolerance range or has
failed. In this case, power is supplied to the inverter from the
charged battery without interruption. The power supply to the
loads is therefore also ensured in the event of a mains failure.
This drains the capacity of the battery and it is discharged.
This status is signalled by the battery symbol lighting up
(Battery LED), as well as an intermittent acoustic signal, at
first every 4 seconds and then every second shortly before
switching off. The initial alarm can be suppressed by pressing
the “Alarm off” button. The alarm is automatically reactivated
when the battery capacity decreases. Depending on the
expansion level, age and condition of the battery and in
particular on the load to be supplied, the standby time can
vary from a few minutes to several hours.
39

The inverter is switched off if the battery voltage drops below
a factory-set minimum voltage value.
Never store the unit in this condition! The discharged battery
system should be recharged within a week at the latest.
When the voltage and frequency are within the tolerance
range again after the mains is restored, the rectifiers switch
back on automatically. The supply of the inverter through the
mains is resumed and the battery charger charges the
battery.
The bar graph LED (LED chain above the pictograph)

If the inverter is overloaded or if overtemperature is detected,
e.g. also if an inverter defect is detected, voltage is supplied
to the load without interruption via the static bypass switch
(SBS) that switches on automatically. This is signalled by the
Bypass LED.
40
Download from Www.Somanuals.com. All Manuals Search And Download.
This so-called passive redundancy protects against the total
failure of the voltage supply on the secured busbar; however,
in this operating mode, mains faults would directly affect the
load. As a result, the electronics continuously attempt to
switch back to "online" / normal operating mode (e.g. when
the overload or overtemperature goes away).
The bypass consists of an inverse-parallel thyristor stack and
functions as an extremely rapidly switching link between a
load and the mains. The synchronization unit ensures that the
frequency and phase of the inverter voltage is synchronized
with the mains and can therefore be switched over without
interruption (within the tolerance limits).
The bar graph LED functions as the display of
the UPS capacity utilisation. The acoustic signal
sounds every 2 seconds during this operating
mode.
i
6.1.4
Manual Bypass
41
Download from Www.Somanuals.com. All Manuals Search And Download.
The manual bypass enables maintenance and service
personnel to perform work on the PROTECT 1. without
having to switch off the load circuit.
If the current supply fails while the manual
bypass is active, a total failure of the load supply
results. For this reason, it should be switched
back to normal operating mode as soon as
possible.
6.1.5
Unit overload
The load on the UPS should never exceed the specified rated
load of the unit. If a unit overload occurs nevertheless (from
105% of the specified unit rated load) then the Fault LED lights
up and an acoustic signal sounds (twice per second). The
connected loads continue to be supplied for a certain length of
time depending on the level of the overload. However, the
connected load must be reduced without delay.
Non-observance of the "unit overload" condition may cause
the total loss of all UPS functions!
Also avoid short-term unit overloads, which may, for example,
occur when connecting a laser printer or laser fax machine.
Do not connect any household appliances or machine tools to
the UPS.
Never connect or switch on any additional loads
to the UPS if there is a mains failure, i.e. if the
UPS is working in emergency power mode!
As a rule, if there has never been an overload during normal
mode, there will not be one in battery mode either.
When the Fault LED lights up in connection with
a continuous acoustic signal, this is an indication
of a deactivating fault. Follow the instructions on
page 49.

Interfaces and Communication
7.1
Computer Interface RS232
For the control of the UPS and convenient reading of status
messages and measured values, various interfaces are
available. The interface protocol is designed for operation with
the "CompuWatch" shutdown and UPS management software
from AEG. Use the supplied RS232 communication cable to
connect your PC. Plug the cable into a corresponding serial
port on your PC.
RS232 interface: The RS232 is connected via the 9-pin Sub-D
socket strip on the back of the unit (no. 8, p. 26/27). Pin
assignment: 2 = TxD; 3 = RxD; 5 = GND.
7.2
Communication Slot
On the back of the UPS, there is a cover (see p. 26/2727, no.
7). When this is removed, additional, optionally available
communication components can be installed there, e.g.:
AS/400 board: Slot board with status messages, realised via
potential-free relay contacts
USB board: Slot board for communication via USB
SNMP board: Slot board for direct connection of the UPS to
the Ethernet network with RJ 45 (TCP/IP)
Details can be found in the description enclosed with the
particular optional component. Other boards in preparation.
Using the communication slot deactivates the
RS232 interface from chapter 7.1.
i
7.3
Shutdown and UPS Management Software
The "CompuWatch" software specially developed for these
purposes by AEG continuously checks the mains supply and
the UPS status.
In conjunction with the “intelligent” UPS, this guarantees the
availability of the EDP components as well as the data
security.
43

Parallel Operation
9.1
Principle of Operation
PROTECT 1. has been designed for parallel operation with n+x
technology (“n” here stands for the number of units required for
load supply, “x” for the degree of redundancy). Up to 3 units of the
same type can be connected in parallel here to increase the
output power and/or achieve higher availability.

The actively redundant parallel operation automatically
switches to power-increasing operation if the output power
requirement exceeds the UPS single block power, i.e. the
degree of redundancy is decreased or is completely eliminated.
Conversely, the active UPS redundancy degree automatically
increases again when the power consumption decreases.
The connection normally takes place in the low-voltage main
distribution, which also contains the external manual bypass
and the following subdistribution of connected load circuits.
Such a parallel board can be purchased in a wall housing incl.
external HU as well as feeder and load distribution board from
AEG Power Solutions via your specialist dealer.
9.2
Set-up / Connection of Parallel Operation Board
The mains connection of each individual UPS takes place in
the same way as described in chapter 5.
The three-phase mains connection secured for
each UPS must always have the same phase
sequence, i.e. all UPS units are supplied at the
input terminals L1, L2 and L3 by the same
phase each time (no mix!).
In UPS bypass mode, the phase L1 is used to
connect the single-phase load with the mains.
The central external manual bypass, which must
have an all-pole design, must also be supplied
by this phase L1.
The UPS outputs are each connected with the parallel
operation busbar via an isolator. The instructions from
chapter 5 apply here too.
The following always holds true for the UPS input and output
conductors: The difference in length in conductors up to 20 m
per UPS can be max. 20% and max. 10% for lengths > 20 m
per UPS.
The jumper installed between “JP1” and “JP2” on the
connection panel of every UPS at the factory must be
removed. The UPS output distribution also has to take place
according to the instructions in chapter 5. In particular, make
sure that the individual switching elements are correctly
labelled, in order to prevent operating errors later as well. The
52

communication of the units switched in parallel takes place
via the 25-pin parallel operation cable(s) included in the scope
of delivery.
For this purpose, first remove the parallel port covers
(no. 5, p. 26/27) and connect the UPS units with each other
with one parallel operation cable each. Use one parallel
operation cable for 2 units and two parallel operation cables for
3 units (do not create a ring structure!).
(Communicative) parallel operating connection
... for 2 units:
... for 3 units:
After connecting the parallel operation cables, fasten the
previously removed parallel port covers. Turn these by 180°
so that the slot of the cover is facing downwards.
The hardware-related installation is now complete.
9.3
Operation of the UPS in a parallel system
The start-up process is uncomplicated, does not require any
prior knowledge and is basically oriented to the procedure
described in chapter 6. If you have obtained the parallel
operation board from AEG Power Solutions, you can find
further special instructions there. The displays in the parallel
system function the same way as described for the individual
UPS units in chapter 8.
9.3.1
Start-Up
1.
Make sure that all connections have been made
according to the installation instructions.
2.
3.
Make sure that all loads are switched off.
Make sure that all “maintenance switch” manual
bypass switches (no. 3, p. 26/27) on the back of
53

each UPS are in the “Bypass” position and all
mains input miniature circuit breakers (no. 2, p.
26/27) on the back of each UPS are in the “OFF”
position.
4.
5.
6.
Check the position of the central external manual
bypass. This must be in the “Bypass” position, i.e.
supply of the load busbar by the supplying mains.
Now close all isolators in the output of each UPS,
i.e. connect the output of each UPS with the
parallel operation busbar.
Now insert the back-up fuses in your low-voltage
main distribution (where the central external manual
bypass as well as the individual UPS systems are
connected to the mains on the input side) or switch
on the corresponding line protection switches there.
The load supply now takes place via the central
external manual bypass, and the parallel
operation busbar is supplied with power via the
integrated manual bypasses of each UPS.
However, the parallel operation busbar and load
busbar are not yet connected to each other at
this time!
i

7.
8.
Now actuate the mains input miniature circuit breakers
(no. 2, p. 26/27) on each UPS one after the other.
Move them to the "ON" position.
Move the “maintenance switch” manual bypass
switches (no. 3, p. 26/27) on the back of each
UPS to the “UPS” position. Finally, fasten the
covers on each UPS again using the 4 respective
screws that were previously removed.
The voltage supply of the parallel operation
busbar now takes place via the integrated
electronic bypass switches of the UPS systems
used. Check this operating state on the display
panel of each UPS = Bypass (chapter 6.1.3).
i
9.
Now actuate your central external manual bypass:
Switch from the “Bypass” position to “UPS operation”,
i.e. connect your load busbar to the UPS parallel
operation busbar.
This is done using a manual bypass switch with
overlapping switching contacts without any
interruption in the load voltage, i.e. completely
interruption-free.
i
10.
Now switch on the inverters of the UPS systems.
To do this, press the ON pushbutton of each UPS
for approx. 2 seconds one after the other.
After switching on, each UPS carries out a self-
test and synchronizes itself with the parallel
operation busbar, while the LED’s for load and
battery state switch on and off consecutively in
i
increasing
order.
After
the
successful
synchronization of all inverters, the Inverter LED
on each UPS lights up a few seconds later,
whereby the UPS systems now work in parallel
normal operating mode and supply the parallel
operation / load busbar with UPS voltage.
The central external manual bypass switch must
be protected against accidental actuation. Never
actuate it when the UPS systems are in inverter
mode.

11.
When the displays are lit as described, switch on
your loads one after the other. When doing this,
take care not to exceed the maximum permitted
load capacity of the UPS systems. Also take into
account the reserve capacities if active
redundancy should be required.
9.3.2
Changes to the parallel system
If you would like to add a UPS to the parallel system or
remove a UPS from the parallel system, this step is always
done by returning the UPS systems to BYPASS operating
mode.
Load supply through mains operation!
(No UPS protection during this measure).
i
First, switch off the inverters of the UPS systems one after the
other (actuate the “OFF” pushbuttons). All UPS systems
function in SBS/bypass operation. Check the operating state
on the operating panels. Next, active the integrated manual
bypasses (no. 3, p. 26/27) on the back of each UPS. To do
this, first remove the 4 screws of the covers on the back.
Put the mains input miniature circuit breakers of each UPS
(no. 2, p. 26/27) to “OFF” position. Use your central external
manual bypass to bypass the loads, i.e. activate the bypass
operation and remove the load supply from the UPS busbar.
The voltage of each UPS is disconnected in its low-voltage
main distribution. You can now expand or reduce your parallel
system. Pay attention to the jumpers “JP1” / “JP2” and the
parallel operation cables. The subsequent start-up is carried
out as described in chapter 9.3.1.
If you only want to switch off a UPS in the
parallel system, press the “OFF” pushbutton
twice in succession to do this. In this way,
individual UPS systems can be disconnected
from the parallel operation busbar.

Maintenance
The PROTECT 1. consists of state-of-the-art, non-wearing
components. We do, however, recommend visual checks
(above all battery and fan checks) at regular intervals (at least
every 6 months) to maintain continuous availability and
operational reliability.
CAUTION!
Ensure that the work area is cordoned off and
always observe the safety instructions!
10.1
10.2
Charging the Battery
The battery is automatically charged when the mains is
connected, irrespective of the operating mode. This is
signalled by the Load LED’s lighting up (see also chapter
4.4.2).
The complete charging time of the battery after a long
discharge time depends especially on the number of
additional external battery units (see chapter 2.3).
Checks
The following maintenance work should be performed:

10.2.1 Visual Check
When visually inspecting the unit, check whether …
♦ there is any mechanical damage or foreign bodies can
be found in the system,
♦ any conductive dirt or dust has accumulated in the unit,
♦ accumulation of dust affects heat supply and
dissipation.
57

CAUTION!
PROTECT 1. must be disconnected from the
power supply prior to carrying out the following
work.
If large quantities of dust have accumulated, the unit should,
as a precaution, be cleaned with dry compressed air, in order
to ensure adequate heat dissipation.
The intervals at which visual checks should be performed are
largely determined by the site conditions.
10.2.2 Checking the Battery
Progressive ageing of the battery system can be detected by
regular capacity checks. Every months, perform
6
measurements to compare the achievable standby times, e.g.
by simulating a mains failure. In this case, the load should
always have approximately the same capacity demand.
Please contact our hotline if the time drops drastically
compared to the previous measurement (see p. 4).
10.2.3 Fan Check
Regularly check the fans for dust build-up and noticeably
untypical noise development. Blocked intake openings must
be cleaned. In the case of unusually loud or uneven running,
please contact our hotline (see p. 4).

Storage, Dismantling and Disposal
11.1
Storage
Long storage times without charging or
discharging the battery at regular intervals may
lead to permanent damage of the battery.
If the battery is stored at room temperature (20 C to 30 C), it
will automatically discharge at a rate of 3-6% per month due
to internal reactions. Storing the battery at temperatures
above room temperature should be avoided. A high storage
temperature also means greater battery self-discharge.
Batteries that are stored at room temperature should be
recharged every six months to maintain their full capacity and
service life.
Connect PROTECT 1. to the mains before
putting it into storage, in order to make sure that
the battery is fully charged. The charging time
should at least match the time specified in
chapter 10.1.
i
11.2
11.3
Dismantling
The system is dismantled in reverse order of the installation
instructions.
Disposal
In the interest of environmental protection and recycling,
please dispose of the individual system components in
accordance with the regulations and legal guidelines when
permanently taking the system out of operation. Please
consider that infringements to these regulations may result in
prosecution.
