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.
STUDER Innotec COMPACT
COMPACT V6.4 7/85
− 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.
− 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.
2 Introduction
The COMPACT is a sine wave inverter with integrated battery charger with many
additional functions, it has been developed to be used as stand-alone (no gridfeeding) AC provider, or as continuous / break-free current supply provider (UPS).
2.1 Principle schematic
STUDER Innotec COMPACT
COMPACT V6.4 8/85
Notes:
(1) The neutral of the appliance is not connected to the earth whatever the
function mode is. If requested and according to the local regulation, an automatic
connection between Neutral and earth in inverter mode only may be done by
installing a bridge internally to the unit. Please contact your installer regarding this
point.
(2) Remote control for remote adjustment of the input limit. (see chap. 4.6.3)
2.2 Description of the main functions
2.2.1 The inverter
The sine wave inverter 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 use a short surge 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 makes a robust and reliable inverter with the highest efficiency. A 1-20 Watt
adjustable charge detection system allows 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 the use of consumer appliances. On the other
side the battery 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 50/55 A, as per the model. The setting is made accordingly to the battery capacity
and power available.
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 The solar charge controller (optional)
With the built-in solar charge controller, the COMPACT is a complete solar-powercenter. 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 RCC-01 can be connected to 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 displayed.
STUDER Innotec COMPACT
COMPACT V6.4 9/85
2.2.6 Remote control for Power Sharing
This remote control RPS-01 can be connected to the COMPACT in the dedicated
plug. The maximum current available from the energy source can be adjusted 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
COMPACT many batteries have to be connected together in parallel and or in series.
Here are 3 examples of connection:
2.3.1 Connection in parallel
2.3.2 Serial connection
STUDER Innotec COMPACT
COMPACT V6.4 10/85
2.3.3 Serial and parallel connection
3 Mounting and installing
3.1 Installation place
The location of the COMPACT must be driven 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
− In mobile installations it is important to keep the vibrations down as low as
possible
3.2 Fixing
3.2.1 Fixing the 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 must be fixed directlyon the a flat, non
flammable surface, with four screws through the four
holes (diameter 5.5mm) which are accessible from
the outside. In motor vehicles, the COMPACT must
be fixed on a flat plate itself 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 IP-23
This cover IP23 (Order ref. CIP-23) can be easily
installed after the fixation of the COMPACT. For
that 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 Connections
3.3.1 General instructions on connecting
− The cable connection on the terminals AC INPUT / AC OUTPUT / 16A 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 / 16A
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.
3.3.2 Protection cover of the terminals connections
The protection is available as an option (Order ref.
CFC-01) to avoid accidental and hazardous contact
on the terminals 230Vac if the unit is mounted in a
non restricted access area.
It is delivered with strain relief clamps for the cable.

COMPACT V6.4 13/85
3.5 Cabling
Connecting the 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 COMPACT must be carried out in the following order. In case of
dismantling this order must be reversed.
3.6 Pre-installation settings
Before you start with the cabling of the 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
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.
3.6.2 Connection to the 230Vac-consumer appliances (AC OUTPUT)
The 230V consumer appliances must be connected to the terminals AC OUTPUT
with cables which cross section has to follow the local rules in force (usually
2.5mm2). Connections are marked as follows “N“ Neutral, “PE“ Earth (connected to
the appliance case), “L“ Live.
Caution: High voltages can be there. Make sure that the 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
terminals AC INPUT with cables which cross section depends on the power source
(usually 2.5mm2). Connections are marked as follows: “N“ Neutral, “PE“ Earth
(connected to the appliance case), “L“ Live.
STUDER Innotec COMPACT
COMPACT V6.4 14/85
3.6.4 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.
3.6.5 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.
3.6.6 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.
3.6.7 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.
3.6.8 Connection to the Remote Control for the „Power Sharing“ (RPS-01)
This remote control is connected with a 20m long cable to a RJ11/6 plug. 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.

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 230Vac alternating voltage
appliance 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 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
automatically 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
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 another in a short
STUDER Innotec COMPACT
COMPACT V6.4 18/85
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
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 too 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 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 automatically. 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 example, an emergency back up system can be started
without any break in the energy supply.
The low voltage is set to 11.6V / 23.2V / 46.4V. These settings are standard for most
batteries. These voltage levels are maintained by the built-in Battery-ManagementSystem of the 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
Programming. Check with your battery supplier which voltage values should be set.

COMPACT V6.4 19/85
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 volt-age 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 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:

These values can be modified by mean of the optional remote control
4.6.3 Equalization charging
Before you program the 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.
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, 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 equalizing it is blinking. Charge cycle with equalization can be started
independently from the actual program. For this purpose the slide switch must be slid
STUDER Innotec COMPACT
COMPACT V6.4 20/85
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.
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.
Equalization mode should never be used when using Gel-Batteries.
4.6.4 Input current repartition (Power sharing)
To manage the power available on the AC INPUT (depends on the supply use) the
COMPACT is equipped with a system usually called “Power sharing” or INPUT power
distribution. 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 COMPACT cannot limit the current, then the generator means to
stop or the circuit breaker means to break before.
4.6.5 Set the INPUT LIMIT (26)
The current available for the COMPACT depends on
the supply used from a motor generator, the network
of a camping or of a shore connection. The value of
the turning knobs INPUT LIMIT (26) must be adjusted
lower or equal to the current 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 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.
4.6.6 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.
4.6.7 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 COMPACT takes into account the battery voltage,
the discharge and charge current as well as the undulation of the voltage. If the
battery and the COMPACT are used according to their technical data, the battery
STUDER Innotec COMPACT
COMPACT V6.4 21/85
state of charge is displayed accurately. In the following cases of use the display can
diverge:
− Battery charge or discharge with too high
currents
− Battery cable cross section too small
− Battery connections badly tightened or corroded
− Charge of the battery with external battery
charger
− Discharge of the battery with users not
connected to the COMPACT
− Work with defective or sulphated batteries
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 COMPACT takes into account, during the charge, only the peaks of the voltage
undulation. As a consequence, the battery voltage at the start of the absorption
stage, measured 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.
The battery charger functions are described by the graphic in chap. 4.6.1.
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 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 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. However if 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 !
STUDER Innotec COMPACT
COMPACT V6.4 22/85
4.7.1 Set the transfer voltage threshold
The voltage threshold of the transfer can be adjusted between 150 to 230V with the
turning knobs (23). From factory this value is 200V. Most appliances can work on this
voltage. 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.
Note : 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
Delay“ OFF, which is on the front side (cable connections side).
The aim of the COMPACT is to supply the appliance 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 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 is programmed with the slide switch (D) on
front plate under the battery connection.
The 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 generator. 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” (D) 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 inbuilt 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.
STUDER Innotec COMPACT
COMPACT V6.4 23/85
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 / 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 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.
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)
In case this function is not wished, it must be modified by programming according to
procedure in chap. 5.4.
4.10 The Remote Control RCC-01
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 as long as 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 descry-bed in
the section „Programming“.
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 built-in Control
Input. 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 from the
STUDER Innotec COMPACT
COMPACT V6.4 24/85
Auxiliary Contact of the
COMPACT. This con-tact is
active in case of an alarm of
the COMPACT.
The Control Input is connected
in parallel to the ON/OFFpush button. The COMPACT
can be switched on or off
through this input with an
impulse button or an impulse
contact.
Caution: No external voltage
should be connected to this
Input Control.
Order Number for Remote Control: RCC-01
Dimensions: H x B x T / 111.5 x 136.5 x 25mm
4.11 The Temperature sensor CT-35
Operating voltage of lead-acid batteries change depends
on the temperature. To correct the operating voltages
according to the actual temperatures, a temperature sensor
can be connected to the COMPACT.
The compensation through the sensor is –3mV/°C/Cell.
Order Number: CT-35
Dimensions: H x B x T / 58 x 51.5 x 22mm
4.12 Remote control for „Power Sharing“ RPS-01
If the Remote control RPS-01 is installed, the
Trimmer (26) “INPUT LIMIT“ has to be set on
the value max.. The COMPACT takes into
account the lowest values set on the inverter
and on the Remote control.
The current available at the COMPACT input
will be determined by the power of the
connected source (generator, grid etc...). The
potentiometer on the RPS-01 must be
adjusted 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 obtained in dividing
2000 Watt by 230V. If the 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 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 COMPACT will break.

COMPACT V6.4 25/85
5 Programming
The COMPACT (except for 60Hz versions) is equipped with a Flash processor
fitted out with EEPROM Memory, which means that even when it is
disconnected from the battery, the parameters that were programmed for the
application remain after a new connection to the battery.
It is possible to reinitialize (RESET) the COMPACT by pressing simultaneously
on the three push buttons 19/20/21 during at least 2 seconds. A beep will
confirm the RESET. The inverter switches off after this operation. It can be
turned on again after the beep. The programmed parameters will remain.

5.4 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
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 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 30 seconds no buttons are pushed, then the settled values
