STUDER INNOTEC COMPACT
User manual COMPACT V4.0 E 5
During operation of COMPACT, high tensions are generated at the connections and inside of the
appliance which could be deadly fatal. Work on the appliance and on the installation should only
be carried out by qualified and trained personnel.
The whole installation connected with the COMPACT must comply with the respective valid codes
and ordinances.
Persons without the written authorization from Studer INNOTEC are strictly forbidden to carry out
any changes or repairs on the appliances. For authorized changes only original parts are to be
used.
The COMPACT may only be used when it has been installed in accordance with these instructions
and all parts have been correctly assembled and installed.
On the IN- and OUTPUT points of the COMPACT only the already selected energy sources and
consumer devices should be connected.
In order to carry out any maintenance or repair work on the COMPACT without danger, all
connections must be disconnected beforehand.
Caution: Even when a COMPACT has been disconnected from the all connections, at the
OUTPUT point there could still be deadly fatal tensions present. To remove these tensions
you must switch on the COMPACT ON with the ON/OFF switch. After one minute the
electronics are discharged and any work can now be safely carried out.
The 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 COMPACT must be protected from water-spray and any
other wet conditions.
The COMPACT may only be connected to lead –acid or lead-gel batteries.
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 area, they should be placed in such a way that there is no danger of short
circuiting through carelessness. Never charge frozen batteries.
The COMPACT is not to be used or sold for life support equipment or applications.
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 the eyes 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.
Under certain conditions COMPACT or a connected generator can start automatically. While
working on an electrical installation you must ensure that these appliances are disconnected
beforehand from the installation.

User manual COMPACT V4.0 E 6
2 Introduction
The COMPACT is a sine wave inverter with integrated battery charger and solar charger controller
with many additional functions, it has been developed to be used as stand-alone (independent of a
grid-system) AC provider, or as continuous / break-free current supply provider.
2.1 Principle schematic
2.2 Description of main functions
2.2.1 The Inverter
The sine wave inverter built in the COMPACT generates a sinusoidal AC voltage with an
exceptionally precise voltage and stabilized frequency. In order to start large electric motors, the
user has the possibility to employ a short-start-power which is 3-times the nominal power of the
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 make-up a robust and
reliable inverter with highest efficiency. A 1-20 Watt adjustable charge detection system serves to
provide the smallest energy consumption and ensures a long life for the battery.
2.2.2 The Transfer system
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 alternating voltage at the
output for use by the connected consumer devices. On the other side the batteries are charged.
The distribution of energy between the consumer devices and battery charger is automatic.
2.2.3 The Battery charger
The built-in battery charger is so arranged that it can charge the batteries quick very completely. A
microprocessor controlled, 3 to 4 Step charging process ensures the optimum charging of the
batteries. The desired charging current can be set continuously from 0 – 55A (C 4000-48: 0 - 50A).
The battery charger is meant for the lead-acid and lead-gel batteries. Thanks to the floating charge
system the batteries can remain continuously connected.

2.2.4 The solar charge controller (optional)
With the built-in solar charge controller, the COMPACT is a complete solar-power-center. In a solar
installation this controller ensures that the batteries are charged correctly. With the COMPACT,
batteries can be charged with a generator and with the solar modules at the same time. The
charging of batteries with both energy sources is carried out fully automatically.
2.2.5 Remote control
As an option, a remote control can be connected to COMPACT. All operating elements and
displays with the exception of the level adjustment are available on the remote control. The remote
control is furnished with a 20m long cable. This cable can go to 40m long. On the remote control
output power and charging current are also shown.
2.3 Battery connections
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 COMPACT many
batteries have to be connected together in parallel and or in series. Following three examples are
shown:

User manual COMPACT V4.0 E 8
2.3.3 Parallel- Series Connection
3 Assembly
3.1 Place of assembly
The location of the COMPACT must be chosen by the following criteria:
Protection from unauthorized handling.
Dry dust free room, no condensation.
Never install directly over the battery and never in a cabinet together with the batteries.
Keep ventilation holes free. The ventilation of COMPACT is designed in such a way that it can only
work efficiently when the appliance is fully laying on its back.
In mobile installation it is important to keep the vibrations down to as low as possible.
3.2 Fixing
3.2.1 Compact
Basically the COMPACT can be installed in any desired location. Preferred is that the appliance be
wall mounted with battery cables downwards. The COMPACT is fixed on the wall with four screws
through the four holes (diameter 5.5mm) which are accessible from the outside. In motor vehicles
COMPACT must be fixed on vibrations reducing elements. The COMPACT must not be fixed on a
combustible base, as the back of the casing can get hot and reach up to 80 degree Celsius.
3.2.2 Protection cover IP23
This cover IP23 (Order ref. CIP-23) can be easily installed after
the fixation of the COMPACT. For that’s release a little the too
screws down and more the tow up. Then it’s possible to pass the
IP 23 cover between the COMPACT and the wall. The cover must
touch the screws. Lock on the four screws, it’s ready.
3.3 Connection
3.3.1 General instructions on connecting
The cable connection on the terminals AC INPUT / AC OUTPUT / 15A 230VAC are carried out
with a screwdriver Nr.1 and the connection on the SOLAR terminal with a screwdriver Nr.2.
The conductor cross section on the terminals AC INPUT / AC OUTPUT / 15A 230VAC of the
connecting cable must be minimum 2.5mm2.
All connecting cables and also the mounted battery cables, must be fixed with strain relief clamps.
The COMPACT is delivered with battery cables already connected.
The battery cables must never be extended. If the extension is unavoidable then the conductor
cross section must be elevated accordingly.
To protect the battery cable, 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 control must be carried out more often.
Connecting must be done by qualified personnel. Material such as cable, connectors and
distribution boxes, fuses etc. used in the installation must comply with the respective valid low-
voltage installation rules and regulations.

3.5 Cabling/wiring
Connecting of the COMPACT is a very important step in the installation. You must take care that
all connecting work is carried out in a clean and correct manner and under no circumstances that a
cable is connected to a wrong terminal.
Connecting of the COMPACT must be carried out in the following order. In case of dismantling this
order must be reversed.
3.5.1 Pre-installation settings
Before you start with the cabling of the COMPACT you must set the type of battery. In case that
sealed-gel batteries are used then you must set the small slide-switch „Equalize“ which is on the
front with the connecting terminals, to OFF position. In case of „normal“ lead-acid – batteries, these
can handle a higher equalizing charge, the same slide switch can be set to ON position. In case of
doubt leave the setting in OFF position.
3.5.2 Connection to battery
Get the batteries ready for connection: Matching battery terminals, matching fuse on a clamp.
Prepare battery cables, if necessary press on cable tabs/shoes. Connect red cable on Plus (+)-
Pole and the black cable on the Minus (-) Pole. On connecting the second cable to the battery pole
a spark is produced, because for a short time high current flows in the COMPACT to charge the
capacitors. For this reason follow strictly the safety measures described in this manual. Check if
the red LED OFF (13) is lit. If it is not lit, press shortly on the switch ON/OFF (19), now OFF should
be lit.
On connecting the battery the COMPACT needs 1 – 2 Minutes to calculate the actual capacity of
the battery. During this time the battery condition is shown as 100% charged. (LED 14 – 17 lit).
If the LED 12 Battery Low/High is lit, the battery charge is too low. If the LED 12 Battery Low/High
is blinking, the battery charge is too high.
Caution: With a wrong battery voltage the COMPACT can be destroyed. (for example: connecting
a C 1600-12 to a 48V-Battery).
Nevertheless, if the COMPACT had been connected with reverse polarity, it is highly probable that
the fuse inside the casing is defect. Before opening the casing cover all terminals must be
disconnected including the battery. If the COMPACT does not function after the changing of the
fuse and correcting of the polarity, it means that it is defect and must be sent for repair.
3.5.3 Connection the 230Vac-Consumer Device (AC OUTPUT)
The 230V consumer device must be connected to the screw terminal AC OUTPUT. For this, use a
3-core cable with a conductor cross section of 2.5mm2. Connections are marked as follows “N“
Neutral, “PE“ Earth, “L“ Live.
Caution: High tension can by there. By sure that’s the compact is turn off (LED 13 alight) before
the connection.

STUDER INNOTEC COMPACT
User manual COMPACT V4.0 E 11
3.5.4 Connection the 230Vac Input (AC INPUT)
The 230V-supply from network or from a generator must be connected to the screw terminals AC
INPUT. For this use a 3-core cable with a conductor cross section of 2.5mm2. Connections are
marked as follows “N“ Neutral, “PE“ Earth, “L“ Live.
3.5.5 Connect the solar modules: SOLAR +/- (Only for solar option)
Solar modules are connected on these terminals. Under no circumstances should any other energy
source i.e. wind generator be connected to these terminals! Only solar modules must be connected
with two cables +/-. Depending on the power of the modules, the cable cross section should be 2.5
up to 6mm2. Before connecting it is necessary to check with a Voltmeter that the voltage of the
Module meets the following values:
C 1600-12 17-25V/30A, C 2600-24 34 – 45V/30A,C 4000-48 68 – 90V/20A.
3.5.6 Connection to Auxiliary Contact
On these tree terminals is a potential free change-over contact). The maximal permitted current
and voltage for this is 16A/250Vac. The DEL 5 “Contact active” show 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.
3.5.7 Connection to Remote control
The Remote Control RCC 01 is connected in the terminal marked „Remote control“ with a RJ11/8
connector. The Remote Control can be plugged IN or plugged OUT during any operation situation.
Push in the connector, without forcing it, until you hear the „click“, now the connector is locked in
place. 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.
3.5.8 Connection to Temperature Sensor (Temp.)
The Temperature sensor CT-35 is connected in the terminal marked „Temp“ with a RJ11/6
connector. The Temperature Sensor can be plugged IN or plugged OUT during any operating
situation. Push in the connector without forcing it, until you hear a „click“, now the connector is
locked in place. 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.

4.5 The Inverter
An Inverter is built in the COMPACT, which generates a sinusoidal alternating voltage of a very
high quality. With this Inverter any alternating voltage consuming device 230Vac up to the nominal
power of your COMPACT can be operated. Thanks to the generous dimensioning of the
COMPACT, you can operate appliances requiring higher power than the nominal power of the
COMPACT for a short time. The COMPACT provide 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
output AC OUT. The actual power of the connected consumer device 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 automatically if
no consuming device is connected and switches ON automatically again if a consuming device 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 position.
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 the other 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 at too high surrounding
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 to high temperature it gives out an acoustic alarm signal. 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 discharging of the lead-acid batteries leads to high losses in capacity and early aging. That is
why battery condition is continuously controlled and supervised. With low voltage 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 automatically. One minute before the
Inverter switch 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 example, 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 batteries.
These voltage levels are maintained by the built-in Battery-Management-System of 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
on nominal load.
All voltage levels can be programmed. See the instructions under the section on Programming.
Check your battery supplier as to which voltage values are necessary to be set.

4.6 The Battery charger
4.6.1 Cycle of charge
The full automatic 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 voltage levels and the charge current. Thanks
to the built-in Float Charge System, the batteries can be left connected for unlimited time with the
Battery Charger switched on.
During the charging phase the consuming devices 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 COMPACT for Equalization-charge you must confirm 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 COMPACT is operating with a lead-acid battery, which is suitable for equalization, the slide
switch „Equalize“ which is on the cable connection side, must be placed in the ON position. In this
setting, at every 25 charge cycles an equalization is carried out for 20 min. (factory setting). During
such a charge cycle the LED 14 is lit. Charge cycle with equalization can be started independently
of the actual program. For this the slide switch must be slid from “OFF” to the “ON” position. 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.
CAUTION: During the equalization process, the batteries produce lot more gas.
DANGER OF AN EXPLOSION !!
4.6.3 Input current repartition (Power sharing)
For manage the power available on the AC INPUT (depend the supply use) the COMPACT is
equipped with a system usually called “Power sharing” or INPUT power distribution. With this
function it’s possible to limit the AC INPUT current assigned to the charger. More current it uses on

STUDER INNOTEC COMPACT
User manual COMPACT V4.0 E 16
the OUTPUT less it’s give to the charger. Priority to the OUTPUT.
When the power sharing is used the LED 200% (red) is lit to point
out that’s the charge is limited.
Caution: If the power use on the OUTPUT is higher than the value
of the INPUT LIMIT (26) the COMPACT limits the current, then the
generator means to stop or the circuit breaker before means to
break.
In option, a remote control (RPS-01, 20m cable) allows the Power
Sharing far from the COMPACT.
4.6.3.1 Set the INPUT LIMIT (26)
The current available for the COMPACT depend of the supply used
i.e. motor generator, network limit in a camping or shore
connections… The value of the turning knobs INPUT LIMIT (26)
must by adjust lower or equal of the current available from the
source.
For example if you have a generator of 2kW you must adjust the
turning knobs 26 to approximately 8.5A. For calculate this, we
divide the nominal power (2000W) by the voltage (230V). If you
have a circuit breaker (i.e. 6A) before the COMPACT, then you set
this value on the turning knobs (26) (i.e. 6A).
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 CURRENT 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.
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. 5.1.2). The correct charging is
indispensable for a safe function and long-life of the
battery.
4.7 The Transfer system
When an ac voltage is at the input AC IN of the COMPACT, the LED 1 AC IN is lit. When this
voltage matches the lowest adjusted value set by the Turning Knob 23 TRANSFER, 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 16A. That means through this system, consuming
devices up to a maximum of al 3700 Watt can be operated. When the Battery Charger is working,
part of this power is used for the charging according with the power sharing system.

User manual COMPACT V4.0 E 17
The Transfer system is protected against overload with an automatic safety fuse on the AC Input
side of the 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 COMPACT generates a true sinusoidal and quartz stabilized
output voltage. When, however the COMPACT is supplied from a grid or a generator 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 COMPACT!
4.7.1 Set the transfer voltage threshold
The voltage threshold of the transfer can by adjust between 150 to 230V with the turning knobs
(23). From factory this value is 200V. Most of appliances can work on this voltage. When the Input
voltages reach the settled value on turning knob, the inverter switch off and the AC INPUT go
directly on the AC OUTPUT. When the voltage INPUT is less of 20V the value set, the transfer is
stop and the OUTPUT switch back on the inverter.
Don’t use the turning knobs “TRANSFERT” (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 Delay“ OFF,
which is on the front side (cable connections side).
The aim of the COMPACT is to supply the consuming device with a break-free alternating voltage.
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 consuming devices. If you have an alternating
voltage back at the input AC IN, transfer system starts up again without 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 COMPACT provides a break-free alternating voltage for
the consuming device. A quick transfer switch is not always sensible nor is it always desired. For
example, when the consuming devices are operated by a small back-up generator. An overload of
a short duration 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
desirable, 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 Solar charge controller (option)
The COMPACT also has a Solar Charge Controller built in. For charging the batteries, Solar
modules can be connected to the screw terminal SOLAR +/-. The in-built controller is a „Shunt
controller“ for the maximum input current of 30A for C 1600-12 and C 2600-24 and 20A for C 4000-
48. The operating voltage of solar panels to be connected must match the actual operating voltage
of the COMPACT and never exceeds the max. rated value.
Under no circumstances should any other systems such as wind-generator be connected at the
input of the Solar Charge Controller.
The Solar Charge Controller works automatically and is always in operation. As soon as the energy
is delivered from the Solar Charge Controller, LED 3 “SOLAR CHARGE” is lit and the batteries are
being charged. The Solar Charge Controller works even when the Battery Charger is functioning.
The way of working is the principally the same as that of the Battery Charger. The function is
described in the section on Battery Charger. The programming and the adjustments are carried out
in accordance with the same conditions. Check with your battery supplier which adjustments must
be carried out for your battery.

4.9 The Multifunctional Contact
In the 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 /16Amp-30Vdc/1A !
With the Push Button 21 „AUXILIARY CONTACT“ the contact can be manually switched on or off
independent of programming and the operating situation. The LED 5 “Contact active” shows the
state 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 COMPACT witch situation is indicated with a LED. There is no limitation to its application and it
is left to your wishes and desires as to where and how you would like to use it. The example and
the setting of this contact are explained chapter 5.4.2.
In factory we program this for a dysfunction 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)
COMPACT is turned off manually or with a fault (LED 13 lit)
4.10 The Remote Control
As an option a Remote Control can
be connected to the COMPACT. All
operating controls and displays
except from level adjustment are
available on the Remote Control.
The Remote Control is supplied
with a 20m long cable. It can be
lengthened to 40m. The Remote
Control is suitable for surface
mounting on the wall or on to a
switch board. It is fixed with 4
screws. The COMPACT can also
be programmed with the Remote
Control. The Programming is
described in the section „Program-
ming“.
The output power and the charging
currents are displayed on the
Remote Control.
In the Remote Control there is an
additional Alarm Contact and a Control
Input built in. These two functions are
available through Tip-jack RJ11/4 for use.
This Auxiliary Contact is Front / Work
Contact (max. 0.5A!), which is
independent of the Auxiliary Contact of the
COMPACT. This contact is active in case
of an alarm of the COMPACT.
The Control Input is connected in parallel to the ON/OFF- push button. The COMPACT can be
switched on or off through this input with an impulse button or an impulse contact.

Therefore check beforehand with your battery supplier.
5.4 Programming the auxiliary contact
5.4.1 Principle
The Auxiliary Contact can be basically programmed for any operating situation of the 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 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) press down for min. 2 seconds. The LED 4 „Program“ is lit as an
indication, that the COMPACT is in program mode.
A lit 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 10 seconds no buttons are pushed, then the settled values are automatically stored and
the COMPACT switches back to normal operating condition.
