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.
− Under certain conditions XP-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 XP-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
Steca XP-COMPACT
XP-COMPACT V5.5 6/57
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 XP-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 XP-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
XP-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 20/37/45 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 Remote control
As an option, a remote control RCC-01 can be connected to XP-COMPACT. All
operating features and displays, save the adjustment levels (22/23/24/26), are
available on the remote 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.

XP-COMPACT V5.5 7/57
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
XP-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
2.3.3 Serial and parallel connection
Steca XP-COMPACT
XP-COMPACT V5.5 8/57
3 Mounting and installing
3.1 Installation place
The location of the XP-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 XP-COMPACT
Basically the XP-COMPACT can be installed in any
desired location. Preferred is that the appliance be wall
mounted with battery cables downwards. The XPCOMPACT is fixed on the wall with four screws through the
four holes (diameter 5.5mm) which are accessible from the
outside. In motor vehicles XP-COMPACT must be fixed on
vibrations reducing elements. The XP-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 XP-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
XP-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 XP-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.
Steca XP-COMPACT
XP-COMPACT V5.5 9/57
− 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
Connecting the XP-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 XP-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 XP-COMPACT you must set the type of
battery. In case sealed-gel batteries are used then you must set the small slideswitch „Equalize“ (E) 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 (E) 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.
In case of doubt leave the setting in OFF position.
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 XP-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.
Steca XP-COMPACT
XP-COMPACT V5.5 12/57
On connecting the battery the XP-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 XP-COMPACT can be destroyed. (for
example: connecting a XPC 1400-12 to a 48V-Battery).
Nevertheless, if the XP-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 XP-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 boxenclosure), “L“ Live.
Caution: High voltages can be there. Make sure that the XP-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 (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.

4.6 The Inverter
An Inverter is built in the XP-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 XP-COMPACT can be operated. Thanks
to the generous dimensioning of the XP-COMPACT, you can operate appliances
requiring higher power than the nominal power of the XP-COMPACT for a short time.
The XP-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.
4.6.1 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.
4.6.2 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.
Steca XP-COMPACT
XP-COMPACT V5.5 16/57
4.6.3 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.
4.6.4 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 XP-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.
4.7 The battery charger
4.7.1 Cycle of charge
The full automatic XP-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 builtin 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
4.7.3 Equalization charging
Before you program the XP-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 XP-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
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.
4.7.4 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 200Ah should be set between 20 – 40A.
The charging current is displayed on POWER MONITOR (25) of the front panel
or on the Remote Control.

4.7.5 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 XP-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 XP-COMPACT are used according to their technical data, the
battery 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 XP-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 XP-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. 4.7.1.
4.8 The Transfer system
When an AC voltage is at the input AC IN of the XP-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.
