•Keep these operating instructions! The manual contains important instructions on the use of the
UPS that should be followed during installation and use of the UPS device and batteries.
•Condensation may occur if the power supply is cold and is brought into a warm place. Therefore,
you should wait at least 2 hours until it starts up.
•To reduce the risk of electric shock, the UPS should be installed in a pollution-free room with
adequate temperature and humidity. The ambient temperature must not exceed 40 ° C.
•Do not install the power supply in a place exposed to direct sunlight or other heat sources.
•Do not connect devices that can overload the UPS output, e.g. laser printers, electric heaters, etc.
•Cables should be connected and arranged in such a way that no one can accidentally step on or
disconnect them.
•The UPS must be connected to the electrical system with an efficient protective earth (GND).
•Do not block the ventilation openings on the UPS. Make sure the vents are exposed and there is a
minimum of 25cm free space for free ventilation.
•The UPS power circuit should be protected with an appropriate overcurrent circuit breaker.
•The UPS has its own battery power source, so there may be voltage on the output strip, even
though the UPS is not connected to the mains.
•Battery handling should be performed by trained personnel who are knowledgeable about battery
operation and take appropriate precautions during its use.
•If it is necessary to replace the battery, use batteries of the same number and parameters, i.e. rated
voltage, capacity and dimensions.
ATTENTION! Do not throw batteries into fire. The battery may explode.
ATTENTION! Do not open or mutilate the battery.
Released electrolyte is harmful to the skin and eyes and may be toxic.
•The battery can present a risk of electric shock. The following precautions should be taken when
working with batteries:
oRemove watches, rings and other metal objects from your hand.
oUse tools with insulated handles.
oWear rubber gloves and boots.
oDo not lay tools or metal parts on top of the battery.
oDisconnect the battery charging source before connecting or disconnecting the battery
terminals.
•Check that the battery is not inadvertently grounded. If present, remove the source of the ground
fault. Contact with any part of a grounded battery can result in electric shock.

2. Transport, unpacking the UPS
Check carefully whether the carton and the contents are not damaged. If any damage is found,
immediately inform the shipping company and the power supply distributor.
Do not throw away the UPS packaging.
1. If no damage is found, carefully open the carton.
2. Unpack all protective elements (sponges, fillers).
3. Gently remove the UPS from the protective film and place it on a clean, flat and stable surface.
To prevent mechanical damage, shock and impact, only transport the UPS in its original
packaging.
All models of the CORE 6K and 10K power supplies are suitable for both horizontal and vertical
mounting.
2.1. Horizontal assembly in the Rack 19 '' cabinet
The CORE series power supply can be mounted in a Rack 19 '' housing. The following space is required
for installation:
•for a UPS of 2U height and depth greater than 60 cm,
•for a 3U high battery module and depth greater than 60 cm.
Each element requires the use of brackets for mounting in a rack.
You can also use the so-called rails. Rail Kit 19 ”- available as optional equipment.
For proper installation:

2.2. Vertical mounting (tower)
To install the power supply in the Tower position, you need to use special stands that secure the power
supply and enable its stable placement in a vertical position. The set of stands includes short and long
connecting elements, depending on the width of the UPS set.

3.2. Connecting external batteries
Make sure there is a battery circuit breaker between the UPS and the battery module.
Before connecting the battery module and the UPS, the circuit breaker must be turned
OFF.
Make sure the number of batteries in the battery module is appropriate for the amount
for which the UPS has been configured. The standard quantity of 12 V batteries for the
UPS is 20.
Connect one end of the battery cable to the appropriate socket on the rear panel of the UPS, the other
end to the socket located on the battery module. In the case of more battery modules, the remaining
connections are made between the supplied battery modules as in the figure below.
If it is necessary to extend the autonomy time, the power supply has the option of connecting a battery
with a much larger capacity, thanks to the fact that it is equipped with an adjustable Charger with a
capacity of 4A. Changes to the settings of the maximum battery charging current are made by an
authorized service of the PSU manufacturer.
When using larger capacity external batteries, placed on racks or in cabinets, special
attention should be paid to the installation of an additional disconnector in the battery
circuit, the correct polarity of the cables connected to the UPS battery and the number of
batteries used.
Incorrect connection of the "+" and "-" wires or connection of the wrong number of
batteries may cause permanent damage to the UPS and the batteries.

UPS adapted for installation in a single-phase, three-wire installation,
TN with a grounded neutral.
The UPS should be connected to a separate electrical installation, made in accordance with the
manufacturer's Installation Recommendations. Installation should be carried out in accordance with
the regulations and rules in force in a given country. The UPS power supply circuit should be protected
with a circuit breaker or a fuse with the trip current value required in the recommendations. It is not
recommended to use residual current devices in the UPS input.
Cables should be connected and arranged in such a way that no one can accidentally
disconnect them.
3.4. Connection of remote EPO switch
The UPS is equipped with an EPO port for connecting a remote emergency stop
switch. / REPO (Remote Emergency Power Off). By default, the EPO port is configured
as NC (normally closed), activation of EPO takes place by breaking the connection
between Pin 1 and Pin 2 (removal of the jumper).
It is possible to change the EPO configuration to NO (normally open) - contact an
authorized service center. Changing the configuration to NO causes the need to remove the jumper
between Pin 1 and Pin 2.
3.5. Control connector of the external EMBS service bypass
The EMBS connector is used to connect the auxiliary contacts of the External
Maintenance Bypass switch to ensure that the UPS inverter is shut down when the
External Bypass is turned on.
The EMBS connector is NO (normally open) type.
A short circuit (between Pin 1 and Pin 2) causes the inverter to shut down.

3.6. Connection of communication options
The UPS has three communication ports:
USB
RS-232
Slot SNMP/AS-400
To enable automatic management and monitoring of the UPS, connect the USB cable supplied with
the device, on one side to the USB socket on the UPS and on the other side to the USB socket on the
computer.
The software provided with the UPS allows you to automate the processes of switching on and off the
receivers connected to the UPS depending on the events that occur on the UPS (e.g. power failure,
low battery level). The software also allows for ongoing monitoring and logging of UPS event history.
RS232 and USB ports cannot be used simultaneously.
The UPS also has an INTELLIGENT SLOT for additional cards, allowing for the use of communication
options. Additionally, you can connect to the device:
•LAN card - allowing communication via LAN / WAN with the use of e.g. protocols: WWW, SNMP,
Modbus TCP,
•AS-400 relay contact card for communication with external supervision systems, e.g. BMS, alarm
control units,
•Modbus card with RS485 port, allowing communication using the Modbus RTU protocol, e.g. with
BMS systems.
