1.5 Precautions  
This manual must be readily available for the user at any time. The user must be familiar  
with the precautions and safety aspects in the country of installation.  
During operation of HP-COMPACT, high voltages are generated at the connections and  
inside of the appliance which could be lethal. Work on the appliance and on the installation  
should only be carried out by skilled and trained people.  
The whole installation connected with the HP-COMPACT must comply with the rules and  
codes in force.  
People without the written authorization from STUDER INNOTEC are strictly forbidden to  
carry out any change or repair on the appliances. For authorized changes only original  
parts are to be used.  
The HP-COMPACT may only be used when it has been installed in accordance with these  
instructions and all parts have been correctly assembled and installed.  
The HP-COMPACT may only be connected to lead-acid or lead-gel batteries.  
Caution: Even when a HP-COMPACT has been disconnected from all connections,  
at the OUTPUT point there could still be deadly voltages present. To remove these  
voltages you must switch on the HP-COMPACT ON with the ON/OFF switch. After  
one minute the electronics are discharged and any work can now be safely carried  
out.  
The HP-COMPACT is only suitable for internal use and under no circumstances should it  
be subjected to snow, rain, or any other wet conditions.  
By installations in motorized vehicles the HP-COMPACT must be protected from water-  
spray and any other wet conditions.  
Caution: In normal use lead-acid and lead-gel batteries give out explosive gases. Never  
smoke or allow a spark or flame in the vicinity of batteries. The batteries must always be  
stored or placed in a well ventilated room, they should be placed in such a way that there  
is no danger of short-circuit through carelessness. Never charge frozen batteries.  
1.6 Special precautions  
While working on batteries there should always be a second person close to you or within  
your voice range, in case help is needed.  
Plenty of fresh water and soap must be ready at hand so that in case of acid coming in  
contact with skin, eyes and clothes, the areas in question can be thoroughly washed.  
If acid enters the eyes, you must thoroughly wash them with cold running water for at least  
15 minutes. It is recommended that you immediately consult a medical doctor.  
Baking powder neutralizes battery acid electrolyte. Always keep some at hand.  
Special care must be taken when working with metal tools near or on the batteries. With  
tools such as screwdrivers, spanners etc. short-circuits can result. Sparks produced by the  
short-circuit can cause an explosion.  
When working on batteries all personal metal items such as rings, necklaces and bracelets  
must be removed. Batteries are so powerful that short-circuit with these items can melt  
them and thus cause severe burns. Always follow the battery manufacturer instructions.

2.2 Description of the main functions  
2.2.1 The inverter  
The sine wave inverter HP-COMPACT generates a sinusoidal AC voltage with an excep-  
tionnlaly precise voltage and stabilized frequency. In order to start large electric motors,  
the user has the possibility to use a short surge power which is 3 times the nominal power  
of the HP-COMPACT.  
The inverter is protected against overload and short-circuit. A power stage with the latest  
MOS-FET power transistors, a toroidal transformer, and a fast regulating system makes a  
robust and reliable inverter with the highest efficiency. A 1-20 Watt adjustable charge de-  
tection system allows the smallest energy consumption and ensures a long life for the bat-  
tery.  
2.2.2 The transfer system  
HP-COMPACT can be connected to an AC source. For example a stand-by emergency  
generator or the AC network. With the transfer system, on one side you have an alternati-  
ing voltage at the output for the use of consumer appliances. On the other side the battery

HP-COMPACT  
park is being charged. The distribution of energy between the consumer appliances and  
battery charger is automatic.  
2.2.3 The battery charger  
The built-in battery charger is so designed that it can charge the battery quickly and fully. A  
microprocessor controlled, Step charging process, ensures the optimal charging of the  
battery. The desired charging current can be set continuously from 0 to 70/90/100/110 A,  
as per the model. The setting is made accordingly to the battery capacity and power avai-  
lable.  
The battery charger is designed for lead-acid and lead-gel batteries. Thanks to the floating  
charge system the batteries can remain continuously connected.  
2.2.4 Remote control  
As an option, a remote control RCC-01 can be connected to HP-COMPACT. All operating  
features and displays, save the adjustment levels (22/23/24/26), are available on the re-  
mote control. It is supplied with a 20m long cable. This cable can be up to 40m long. On  
the remote control, output power and charging current are also displaid.  
2.2.5 Remote control for Power Sharing  
This remote control RPS-01 can be connected to the HP-COMPACT in the gland for the  
temperature sensor. The maximum current available from the energy source can be ad-  
justed by the turning button.  
2.3 Battery connecting  
Lead-acid batteries are normally available in blocks of 2V, 6V or 12V. In most cases, to  
generate the necessary operating voltage and the capacity of the batteries for the HP-  
COMPACT many batteries have to be connected together in parallel and or in series. Here  
are 3 examples of connection:

HP-COMPACT  
3.2 Fixing  
3.2.1 HP-COMPACT  
Basically the HP-COMPACT can be installed in any desired location but only vertically.  
First of all the plate supplied along with the HP-COMPACT must be screwed firmly (due to  
the weight of the device) on the wall. Then the HP-COMPACT is hooked on the plate and  
screwed underneath.  
Cautious: the fixing must be fully made otherwise the HP-COMPACT may fall and cause  
important damages.  
In motor vehicles HP-COMPACT must be fixed on vibrations reducing elements. The HP-  
COMPACT must not be fixed on a combustible base, as the back of the casing can get hot  
and reach up to 60 degrees Celsius.  
3.3 Connections  
3.3.1 General instructions on connecting  
The cable connection on the terminals AC INPUT and AC OUTPUT must be carried out  
with a screwdriver Nr.3 and the connection of the AUX RELAY terminal with a screwdriver  
Nr.2.  
The conductor cross section on the terminals AC INPUT / AC OUTPUT / must comply with  
the local rules.  
All connecting cables and also the battery cables must be fixed with strain relief clamps.  
The fuses supplied with the HPC4024, 5048 and 7048 have to be installed (see descrip-  
tion in 3.4). The cable cross section for the HP 2512, 4024, 5048 and 7048 is resp. 95, 70,  
50 and 70 mm2 and their length must be as short as possible (max. 2m).  
The fuse supplied with the product (save for HPC 2512) does not protect the battery ca-  
bles.  
To protect the battery cables, a fuse corresponding to the conductor cross section must be  
fixed directly on to the battery.  
All cables must be tightly screwed in place. For safety, a yearly control is recommended. In  
mobile installations controls must be carried out more often.  
Connecting must be done by qualified people. Material such as cable, connectors and dis-  
tribution boxes, fuses etc. used in the installation must comply with the respective valid  
low-voltage installation rules and regulations in force.  
3.3.2 Protection cover of the terminals connections  
The protection cover must to be closed after any service on the appliance.

3.5 Cabling  
Connecting the HP-COMPACT is a very important step of the installation. You must take  
care that all connection work is carried out in a clean and correct way and that under no  
circumstance a cable is connected to a wrong terminal.  
Connecting of the HP-COMPACT must be carried out in the following order. In case of  
dismantling this order must be reversed.  
User manual

STUDER INNOTEC  
HP-COMPACT  
3.6 Pre-installation settings  
Before you start with the cabling of the HP-COMPACT you must set the type of battery. In  
case sealed-gel batteries are used then you must set the small slide-switch „Equalize“  
which is on the front with the connection terminals, in OFF position. In case of „normal“  
lead-acid – batteries, these can handle a higher equalizing charge, the same slide switch  
can be set in ON position. In case of doubt leave the setting in OFF position.  
This will allow an equalizing cycle (higher end of charge voltage) during the next charge  
process. Since then equalizing will occur every 25 usual cycles.  
3.6.1 Connection to battery  
3.6.1.1 On the appliance side  
Mount the supplied glands on the battery cable before the setting of the cable terminal. Set  
the cable terminal and mount the glands on the appliance. Repeat the process for the sec-  
ond battery cable.

3.6.1.2 On the battery side  
Caution: before connecting the battery, check carefully the voltage and the battery polarity  
with a voltmeter. A polarity reverse will seriously damage the inverter (for example: con-  
necting a HPC2512 to a 48V-Battery).  
Get the batteries ready for connection: suitable terminals, fuse on one of the connection  
points, cable in good shape with, if necessary, terminals rightly set. Mount the red cable on  
the positive (+) pole, and the black cable on the negative (-) pole of the battery.  
While connecting the second cable, a spark due to the charge of the capacities at the input  
stage is normal. In the same time an acoustic signal tells that the control processor has  
started. All LED’s of the synoptic light during a short time, then the synoptic shows that the  
appliance has stopped. The LED “OFF” (13) must be turned on.  
After the battery connection, the battery state-of-charge LED shows a 100% capacity dur-  
ing 1 to 2 minutes, the necessary time for the processor to compute again the current  
state-of-charge of the battery.  
If the LED “Battery Low/High” (12) is lighting, the battery voltage is too low. If it is blinking,  
the battery voltage is too high. Caution: a battery voltage too high or inappropriate can se-

riously damage the HP-COMPACT. For instance the connection of a 24 V battery with the  
HP-COMPACT 2512.  
If by mistake the HP-COMPACT has been wrongly been connected (reverse battery polar-  
ity) it is likely that the internal protection fuse has melted and has to be replaced. In that  
case it is necessary to disconnect all connections to the HP-COMPACT, including the bat-  
tery. If after the fuse replacement and after re-connection of the battery with the right polar-  
ity, the HP-COMPACT remains out of order, it must be brought back to your merchant for  
service.  
3.6.2 Connection to the 230Vac-consumer appliances (AC OUTPUT)  
The 230V consumer appliances must be connected to the terminals AC OUTPUT with ca-  
bles which cross section has to follow the local rules in force (usually 2,5mm2). Connec-  
tions are marked as follows “N“ Neutral, “PE“ Earth (connected to the appliance box), “L“  
Live.  
Caution: High voltages can be there. Make sure that the HP-COMPACT is turned off (LED  
13 lighting) before the connection.  
3.6.3 Connection to the 230Vac Input (AC INPUT)  
The 230V-supply from network or from a generator must be connected to the input termi-  
nals AC INPUT with cables which cross section depends on the power source (usually  
2,5mm2). Connections are marked as follows: “N“ Neutral, “PE“ Earth, “L“ Live (connected  
to the appliance case).  
3.6.4 Connection to Auxiliary Contact  
This contact is a potential free change over contact The currents and voltages allowed for  
this contact are max. 16A/250Vac. The LED 5 “Contact active” shows the position of them:  
alight mind active and off mind non-active. The schematic view of the connections on the  
front, show the relay in the non-active mode.  
3.6.5 Connection to Remote control  
The Remote Control RCC-01 is connected in the terminal marked „Remote control“ with a  
20m long cable and a RJ11/8 connector. The Remote Control can be plugged IN or  
plugged OUT during any operation situation. Push in the connector softly until you hear the  
„click“ showing that the connector is locked. The same applies to the plug in the Remote  
Control.  
The length of the cable for Remote Control should not exceed 40m. We deliver it with 20m  
cable.  
3.6.6 Connection to Temperature Sensor (Temp.)  
The temperature sensor CT-35 is connected in the terminal marked „Temp“ with a 3m long  
cable and a RJ11/6 connector. The temperature sensor can be plugged IN or plugged  
OUT during any operating situation. Push in the connector softly until you hear the „click“  
showing that the connector is locked. The temperature sensor must be glued to the wall of  
the battery or near it. The Temperature Sensor cable must not be tied together with the  
battery cables or laid in a rope/bundle.  
3.6.7 Connection to the Remote Control for the „Power Sharing“ (RPS-01)  
This remote control is connected with a 20m long cable and a RJ11/6 connector in the  
connection terminal „F“ (Temp. sensor). It can be connected and disconnected at any time.  
Push in the connector softly until you hear the „click“ showing that the connector is locked.  
In case the remote control is connected together with the Temp. sensor, a short cable with  
a Y-connector will be connected in the terminal „F“ (can be supply as an option).

An Inverter is built in the HP-COMPACT, which generates a sinusoidal alternating voltage  
of a very high quality. With this Inverter any 230Vac alternating voltage appliance up to the  
nominal power of your HP-COMPACT can be operated. Thanks to the generous dimen-  
sioning of the HP-COMPACT, you can operate appliances requiring higher power than the  
nominal power of the HP-COMPACT for a short time. The HP-COMPACT provides up to  
3-times the nominal power to start motors.

The Inverter mode is displayed through LED 9 (Inverter). If the Inverter Mode is disabled  
(see chap. 5.5) LED 9 will blink. If the LED 9 is lit, the Inverter is in operation and you have  
230Vac at the output AC OUT. The actual power of the connected appliance is displayed  
on the power monitor 25 and on the Remote Control.  
4.5.1 Charge detection system „Standby“  
In order to avoid unnecessary discharge of the battery, the inverter switches OFF auto-  
matically if no appliance is connected and switches ON automatically again if appliance is  
connected. The LED 8 blinks if the inverter is in Standby-Mode. The switching-on/starting  
level can be adjusted with the turning knob 24 „STANDBY”. Adjusting the switching-on  
level is as follows: Switch off all consuming devices, turn the Turning Knob 24 to the right  
until the LED 8 is blinking, switch on the smallest consuming device (i.e. Mobile phone  
charger), turn the Turning Knob slowly to the left until LED 8 is lit.  
If the Standby-Mode is not wanted, turn the Turning Knob 24 to the left, to the OFF posi-  
tion.  
4.5.2 Overload  
If the Inverter is too long or too heavily overloaded, it switches off. The LED 11 „Overload“  
is lit and LED 13 „OFF“ blinks. After ca. 10 seconds the Inverter switches on automatically.  
If the Inverter is overloaded four times one after another in a short time, then it no longer  
switches on automatically. The LED 13 remains lit. Press the push button 19 „ON/OFF“ in  
order to switch on the Inverter.  
4.5.3 Overheating (Over Temp.)  
If the Inverter has been overloaded for a long time or it has been working in too high sur-  
rounding temperatures, it will switch off. The LED 10 „Over Temp.“ is lit and the LED 13  
„OFF“ blinks. After cooling down, the inverter switches back on automatically. One minute  
before the inverter switches off for too high temperature it gives out an acoustic alarm sig-  
nal. If the Auxiliary Contact has been programmed to detect the high temperature then it  
synchronizes the relay with the alarm signal. In this way, for example, an emergency back-  
up system can be started without any break in the energy supply.  
4.5.4 Battery Condition  
Deep discharge of the lead-acid batteries leads to high losses in capacity and early aging.  
That is why the battery condition is continuously controlled and supervised. With low volt-  
age the inverter switches off. The LED 12 „L/H Batt.“ is lit and the LED 13 „OFF“ blinks.  
When the battery voltage gets up to 12.1V / 24.2V / 48.4V, the Inverter switches on auto-  
matically. One minute before the Inverter switches off due to low voltage it gives out an  
acoustic alarm signal. If the Auxiliary Contact has been programmed to detect the low  
voltage then it synchronizes the Aux. Contact with the alarm signal. In this way, for exam-  
ple, an emergency back up system can be started without any break in the energy supply.  
The low voltage is set to 11.8V / 23.6V / 47.2V. These settings are standard for most bat-  
teries. These voltage levels are maintained by the built-in Battery-Management-System of  
the HP-COMPACT by matching the load and the battery condition.  
This setting is comparable with the levels of 10.8V/ 21.6V / 43.2 which are given for most  
batteries at nominal load.  
All voltage levels can be programmed. See the instructions under the section on Pro-  
gramming. Check with your battery supplier which voltage values should be set.

4.6 The battery charger  
4.6.1 Cycle of charge  
The full automatic HP-COMPACT Battery Charger is adjusted at the factory so that most  
lead-acid and lead-gel batteries can be charged to the maximum. As soon as the minimum  
alternating voltage for the AC IN set on the Turning Knob 23 is available at the input (LED  
1 AC IN is lit), the Battery Charger is switched on automatically (LED 2 CHARGER is lit).  
The battery is fully automatically charged matching to the charge level, the adjusted volt-  
age levels and the charge current. Thanks to the built-in Float Charge System, the batter-  
ies can be left connected for unlimited time with the Battery Charger switched on.  
During the charging phase the appliances at the outlet AC OUT are continually supplied  
with power (LED 8 AC OUT is lit).  
The charger functions are shown in the following diagram:

4.6.2 Equalization charging  
Before you program the HP-COMPACT for Equalization-charge you must check with your  
supplier that the batteries are suitable for this process.  
Equalization is recommended for the lead-acid batteries in order to mix well the electrolyte  
fluid and to clean the lead plates.  
Equalization mode should never be used when using Gel-Batteries  
If the HP-COMPACT is operating with a lead-acid battery, which is suitable for equali-  
zation, the slide switch „Equalize“ which is on the cable connection side, must be placed in  
the ON position. In this setting, every 25 charge cycles an equalization is carried out for 20  
minutes (factory setting). During such a charge cycle the LED 14 is lit and during equaliz-  
ing it is blinking. Charge cycle with equalization can be started independently from the ac-  
tual program. For this purpose the slide switch must be slid from “OFF” to the “ON” posi-  
tion. The LED 14 will light up. If the periodic equalization is not required, slide switch must  
be slid back to the „OFF“ position after the completion of the manual cycle.  
The equalizing voltage can be changed. How to proceed is explained in chap. 5.3.  
Batteries not designed for equalize should never been charged this way.  
CAUTION: During the equalization process, the batteries produce a lot more gas.

DANGER OF AN EXPLOSION !! The battery room must be well ventilated.  
4.6.3 Input current repartition (Power sharing)  
To manage the power available on the AC INPUT (depends on the supply use) the HP-  
COMPACT is equipped with a system usually called “Power sharing” or INPUT power dis-  
tribution. With this function it is possible to limit the AC INPUT current assigned to the  
charger. The more current it uses on the OUTPUT the less it gives to the charger. Priority  
to the OUTPUT. When the power sharing is used the LED 200% (red) is lit to point out that  
the charge is limited.  
Caution: if the power use on the OUTPUT is higher than the value of the INPUT LIMIT (26)  
the HP-COMPACT cannot limit the current, then the generator means to stop or the circuit  
breaker means to break before.  
4.6.3.1 Set the INPUT LIMIT (26)  
The current available for the HP-COMPACT depends on the  
supply used from a motor generator, the network of a camp-  
ing or of a shore connection. The value of the turning knobs  
INPUT LIMIT (26) must be adjusted lower or equal to the cur-  
rent available from the source.  
For example if you have a generator of 2kW you must adjust  
the turning knobs 26 to a max. 8.5A. To calculate this, one  
divides the nominal power (2000W) by the voltage (230V). If  
you have a circuit breaker (i.e. 6A) before the HP-COMPACT,  
then you set this value on the turning knobs (26) (i.e. 6A).

This adjustment can be done remotely with the optional RPS-01 (see section 3.6.7). In that  
case the smallest values will be taken into account.  
4.6.4 Charging current  
The maximum charging current for the battery can be adjusted with the Turning Knob 22  
(CHARGER). The charging current of the battery should be set to approximately 10 – 20%  
of the battery capacity (at C10). This means that the charging current for a battery with  
300Ah should be set between 30 – 60A.  
The charging current is displayed on POWER MONITOR (25) of the front panel or on the  
Remote Control.  
4.6.5 Battery Condition  
Built-in microprocessor with a specially developed algorithm calculates the actual state of  
charge of the battery and displays it on LED 15 – 18. The LED 14 is lit when the system is  
carrying out a charge cycle with equalization.  
Notice: the exact measure of the battery state of charge with electrical parameters is al-  
most impossible. The display of the state of charge is always more or less precise. The  
measure system built in the HP-COMPACT takes into account the battery voltage, the dis-  
charge and charge current as well as the undulation of the voltage. If the battery and the  
HP-COMPACT are used according to their technical data, the battery state of charge is  
displaid accurately. In the following cases of use the display can diverge:

Battery 25 – 50%  
Battery 0 – 25%  
This means that the display can, within few minutes during the charge, commute from 25%  
to 75% or during the discharge, to the opposite direction.  
As many of the working cases mentioned above often occur, the measure system of the  
HP-COMPACT takes into account, during the charge, only the peaks of the voltage undu-  
lation. As a consequence, the battery voltage at the start of the absorption stage, meas-  
ured by a voltmeter will appear deeper. By decrease of the charge current the voltage will  
reach the exact values.  
For safety reasons, you must get the recommended charge voltage and charge currents  
from your battery supplier. The voltage levels and charge characteristics can be changed  
through Programming. The instruction for programming of battery charger is in the section  
„Programming“ (Chap. 5.3). The correct charging is mandatory for a safe function and a  
long-life of the battery.  
4.7 The Transfer system  
When an AC voltage is at the input AC IN of the HP-COMPACT, the LED 1 AC IN is lit.  
When this voltage matches the lowest adjusted value set by the Turning Knob 23 TRANS-  
FER, and the frequency is between 44Hz and 65Hz, this voltage is switched directly to the  
battery charger and to the output AC OUT. The LED 7 TRANSFER is lit. The inverter is  
switched off and the battery charger switched on. This process is automatic, unless the  
charger mode or the transfer mode is disabled (see Chap. 5.5).  
The maximum current of the Transfer switch is 30A (50A for HPC-7048). That means  
through this system, appliances up to a maximum of al 6900 Watt at 230V(11500W for  
HPC7048) can be operated. When the Battery Charger is working, part of this power is  
used for charging according to the power sharing system.  
The Transfer system is protected against overload with a circuit breaker on the AC Input  
side of the HP-COMPACT. If the system has been overloaded, the button/pin of the fuse  
will pop out. To put the automatic safety system back in to operating you must push this  
pin back.  
Note: in the Inverter operation, The HP-COMPACT generates a true sinusoidal and quartz  
stabilized output voltage. However if the HP-COMPACT is supplied from a grid or a gen-  
erator and the transfer contact is active, then you have at the output AC OUT the same  
voltage as that at the input. This voltage can not be modified by the HP-COMPACT !  
4.7.1 Set the transfer voltage threshold  
The voltage threshold of the transfer can be adjusted between 150 to 230V with the turn-  
ing knobs (23). From factory this value is 200V. Most appliances can work on this voltage.  
User manual  
HP-COMPACT V3.0 E  
17  
STUDER INNOTEC  
HP-COMPACT  
When the Input voltages reach the selected value on turning knob, the inverter switches off  
and the AC INPUT goes directly on the AC OUTPUT. When the voltage INPUT is less of  
20V the value set, the transfer is stopped and the OUTPUT switches back on the inverter.  
Don’t use the turning knobs “TRANSFER” (23) to adjust the AC OUTPUT voltage !  
This is only it’s only a voltage threshold level to enable or disable the transfer.  
4.7.2 FAST (UPS)- MODE for the Transfer Switch  
The quick and break free Transfer mode is programmed with a slide switch „Transfer De-  
lay“ OFF, which is on the front side (cable connections side).  
The aim of the HP-COMPACT is to supply the appliance with a break-free alternating volt-  
age. When the incoming voltage AC IN no longer matches values which have been set  
with the Turning Knob 23, the Inverter switches on at once. The transfer is carried out in  
0.02 seconds. This quick transfer ensures a break-free function for most appliances. If you  
have an alternating voltage back at the input AC IN, transfer system starts up again with-  
out any break, and the inverter is stopped.  
4.7.3 Delayed mode of the Transfer System  
The delayed mode of the transfer system „Transfer Delay ON“ is programmed with the  
slide switch on front with the cable connections. The HP-COMPACT provides a break-free  
alternating voltage for the appliance. A quick transfer switch is not always sensitive nor is it  
always desired. For example, when the appliances are operated by a small back-up ge-  
nerator. An overload of a short period on such a generator, i.e. start of a vacuum cleaner  
etc., has the effect of decreasing the voltage for a short time. As in such cases the transfer  
to the Inverter is not desired, the transfer system can be programmed with a delay. When  
the slide switch (Transfer delay) is in the „On“ position, the transfer to the inverter takes  
place with a delay of 5 seconds. If the voltage falls below 100Vac, the transfer takes place  
without delay ! The transfer switching to the Inverter takes place without any break.  
4.8 The Multifunctional Contact  
In the HP-COMPACT there is a built-in programmable power relay. The potential-free  
change-over contact (NO – NC) of this power relay is connected to the screw terminal  
AUX CONTACT.  
Maximum Contact load: 230Vac / 12Vdc / 24Vdc / 16A !  
> 36Vdc / 3A !  
With the Push Button 21 „AUXILIARY CONTACT“ the contact can be manually switched  
on or off independently from programming and from the operating situation. The LED 5  
“Contact active” shows the status of the contact. The drawing up the screw terminal “AUX  
CONTACT” is the inactive position mode, LED 5 “Contact active” off.  
The switching on and off of this contact can be freely programmed for every operating  
situation of the HP-COMPACT witch situation is indicated with a LED. There is no  
limitation to its application and it is left to your wishes as to where and how you would like  
to use it. The example and the setting of this contact are explained in chapter 5.4.2.  
In factory we program this for a disfunctioning alarm. The contact is active when one of  
these situations is detected:  
Over temperature (LED 10 lit)  
Overload (LED 11 lit)  
Over or less voltage of batteries (LED 12 lit or blinking)  
HP-COMPACT is turned off manually or with a fault (LED 13 lit)  
In case this function is not wished, it must be modified by programming according to pro-  
cedure in chap. 5.4.

4.11 Remote control for „Power Sharing“  
If the Remote control RPS-01 is installed, the Trimmer (26) “INPUT LIMIT“ has to be set  
on the value max.. The HP-COMPACT takes into account the lowest values set on the  
inverter and on the Remote control.  
The current available at the HP-COMPACT input will be de-  
termined by the power of the connected source (generator,  
grid etc...). The potentiometer on the RPS-01 must be ad-  
justed lower or equal to max. value of the power source.  
For instance if the source is a generator of 2000 Watt, the  
potentiometer has to be set at max. 8A. This value is ob-  
tained in dividing 2000 Watt by 230V. If the HP-COMPACT  
is connected to a power source which is protected by a 6A  
circuit breaker, the potentiometer must be set at a max.  
value of 6A.  
Caution: the HP-COMPACT will not limit if an appliance draws more current than  
available from the source ! This means that the connected generator will be over-  
loaded or that the circuit-breaker before the HP-COMPACT will break.

5.4 Auxiliary contact  
5.4.1 Principle  
The Auxiliary Contact can be basically programmed for any operating situation of the HP-  
User manual  
HP-COMPACT V3.0 E  
21  
STUDER INNOTEC  
HP-COMPACT  
COMPACT which is indicated with a LED. The programming is possible for one or more  
operating situations. If the contact is programmed for many situations, it is activated as  
soon as the HP-COMPACT finds itself in any one of the programmed situations. That  
means that the work of the contact meets that of the logic OR–Function.  
5.4.2 The programming of the Auxiliary Contact is carried out in the following  
Steps  
The Push Button 21 (Program) presses down for min. 2 seconds. The LED 4 „Program“ is  
lit as an indication, that the HP-COMPACT is in program mode.  
A blinking LED shows the programmed condition for the auxiliary contact (LED 10/11/  
12/13 factory setting).  
With the Push Button 20 (select), select the desired condition in which the contact should  
be activated.  
With the Push Button 19 (Change status) confirm or change the status for this condition.  
If desired, with the Push Button 20 (select) select another condition in which the contact  
should be activated.  
With the Push Button 19 (Change status) confirm or change the status for this condition.  
If during 20 seconds no buttons are pushed, then the settled values are automatically  
stored and the HP-COMPACT switches back to normal operating condition.  
5.4.3 Auxiliary Contact as generator starter  
As per the battery capacity  
When in the programming of the Auxiliary Contact, the Battery Capacity (LED 15-18) is  
used as a condition, you must then take note of the following requirements.  
If you have to start an emergency back-up supply with a battery having a certain residual  
capacity, then two battery levels must be programmed. The first (i.e. Battery 25% LED 17)  
for the starting or activating the Auxiliary Contact and the second (i.e. Battery 100%  
LED15) for stopping or disabling the Auxiliary Contact. Programmed like this the Auxiliary  
Contact works with the lowest set condition and stops when it has reached the highest  
programmed condition through charging.  
Example: start of a genset with the HP-COMPACT  
In order to program the auxiliary contact to start at 25% and to stop at 75% of the battery  
state-of-charge, here is the procedure to follow:  
- Press the key AUX. CONTACT (Program) 21 during at least 2 seconds. Then the  
states will be displaid blinking (factory settings LED’s 10/11/12/13). As these states  
are not wished for the start of the genset, they must be disabled.  
- With the key (select) 20, select the LED’s to disable (the active LED’s are blinking)  
and disable them with the key 19 Change Status. Select the other LED’s to switch  
off with the key (select) 20 and switch them off with the key 19 Change Status until  
all are disabled.  
- Then select the LED 17 with the key (select) 20 and activate the contact with the  
key 19 Change Status. The genset will start once the LED 17 switches of.  
- Then select the LED 16 with the key (select) 20 and activate the contact with the  
key 19 Change Status. The genset will stop once the LED 16 switches on.

As per the inverter output power (not available with some special executions)  
Activating the auxiliary contact for the generator start can be programmed also on a pre-  
determined output power of the inverter. The auxiliary contact will be activated if the in-  
verter output power exceeds 80% of the inverter nominal power during 3 minutes and/or  
100% during 30 seconds.  
The auxiliary contact will remain activated 30 minutes after the input current has come  
back to a value lower than the one adjusted by the “INPUT LIMIT” (chap. 4.6.3). In other  
words, the contact will be deactivated 30 minutes after the lighting out of the LED 200%.  
This programming is achieved accordingly to chap. 5.4.2 of the user manual and by acti-  
vating the contact on LED 100% of “Power Monitor” (25).  
5.4.4 Power cut of the second priority loads  
The auxiliary contact can also be used to cut the power of less priority loads when the bat-  
tery state of charge is lower than a given threshold. In that case, only one of the battery  
state of charge, or the “transfer” function will be programmed as power cut criteria.  
The second priority loads will be supplied only when the genset is ON or when the battery  
has a sufficient threshold.  
5.4.5 Manual operating of Auxiliary Contact  
The Auxiliary Contact can be operated at any time with the Push Button 21 (AUX. CON-  
TACT). The LED 6 „Contact manual“ lights up as information that the Contact is manually  
operated, and LED 5 „Contact active“ lights up when the Contact is active. By pushing the  
Push Button 21 a second time, the Contact is disabled. By pushing it the third time, auto-  
matic functions are restored.  
5.5 Disabling some of the HP-COMPACT functions  
Each different function charger, inverter and transfer can be disabled. This is useful for  
specific applications witch required to disable some of these three functions.  
If you press the button (20) more than 2 seconds you can have access to the different  
possibilities shown in the following diagram.  
In programming mode the display shows only the different types of program with the three  
LED’s 2, 7 and 9 to each function. To change the type of programming, press shortly the  
button 20 until you reach the right function used according to the table below. After 20  
seconds the HP-COMPACT exits the programming mode and loads the new change.  
In user mode, the disabled functions are displayed by blinking LED. So you can see which  
mode is disabled.
