 Keep this manual! The manual contains important instructions for the use of the UPS, which should
be followed during the installation and use of the UPS device and batteries.
 Condensation may occur if the UPS is cold and is brought into a warm room. Therefore, you should
wait at least 2 hours until it starts.
 To reduce the risk of electric shock, the UPS should be installed in a dust-free room with appropriate
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 sources of heat.
 Do not connect devices to the UPS output that may overload it, e.g. laser printers, electric heaters,
etc.
 Cables should be connected and placed in such a way that no one can accidentally step on or
disconnect them.
 The UPS must be connected to a socket with a pin with a functional protective conductor (PE).
 Do not block the ventilation openings in the UPS. Make sure that the vents are uncovered and there
is a minimum of 25 cm of free space for free ventilation.
 The UPS power socket should be protected by a suitable overcurrent circuit breaker.
 The UPS has its own battery power source, so there may be voltage at the output sockets even
though the UPS is not connected to the mains.
 Batteries should be handled by trained personnel who are familiar with the use of batteries and
take appropriate precautions when using them.
 If it is necessary to replace the batteries, use batteries with the same number and the same
parameters, i.e. rated voltage, capacity and dimensions.
ATTENTION! Do not throw batteries into fire. The battery may explode.
ATTENTION! Do not open or damage the battery. The released electrolyte is harmful to
the skin and eyes. It can be toxic.
 The battery may present a risk of electric shock. Observe the following precautions when working
with batteries:
o Remove watches, rings and other metal objects from your hand.
o Use tools with insulated handles.
o Wear rubber gloves and boots.
o Do not place tools or metal parts on top of the battery.
o Disconnect 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 cause electric shock.

2. Transportation, UPS unpacking
Check carefully that the carton and contents are not damaged. If any damage is found, immediately
inform the transport company and the distributor of the power supply.
Do not throw away the power supply packaging.
1. If no damage is found, carefully open the carton.
2. Unpack all protective elements (sponges, fillers).
3. Carefully remove the UPS from the protective film and place it on a clean, flat and stable surface.
Only transport the UPS in its original packaging to prevent mechanical damage, shocks
and impacts.
2.1. Horizontal installation in a 19'' rack
The CORE series power supply can be mounted in a 19'' Rack. Both the UPS and the battery module
require 2U space for installation. Each item requires optional brackets (rack rails) for mounting in the
rack.
For proper installation, you must:
Step 1 Step 2
2.2. Vertical installation (Tower)
To install the power supply in the Tower position, use special supports that secure the power supply
and enable its stable positioning in a vertical position. In order to place the power supply correctly,
you should:

1. Programmable output sockets: can be switched off, intended for less critical loads.
2. Fixed output sockets: for connecting critical loads. Voltage is present on these outlets
whenever the UPS is operating in normal or battery mode.

3.2. Connection of internal batteries
For safe transportation of the UPS, the battery cables inside the UPS are disconnected. Before
installing the UPS, please follow the instructions below to connect the batteries.
Step 1 Step 2 Step 3
Remove the front panel. Connect the battery plugs. Install the front panel.
3.3. Connection of external batteries
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 shown in the figure below.

If additional battery modules or external batteries are connected, the UPS should check
and, if necessary, correct the setting of the connected battery capacity.
After connecting the external battery module, switch on the battery circuit by lifting the
protection on the back cover of the battery module (Battery Breaker).
3.4. Power connection
The power supply should be connected to an electrical outlet equipped with a pin with an operational
protective conductor using the cable supplied by the manufacturer. The electrical socket to which the
power supply is connected should be protected by a circuit breaker. The recommended cross-section
of the power cable in the electrical installation is 2.5 mm2. It is recommended to use a separate socket
to power the UPS, protected by its own circuit breaker. The current value for the correct selection of
protection on the UPS power supply is given below.
Power of UPS Minimum protection value
1 kVA 10 A
2 kVA 16 A
3 kVA 20 A
3.5. Connecting loads to the UPS output
The UPS is equipped with standard IEC 320 sockets. Connecting receivers requires the use of standard
IEC 320 C13 - C14 (10A) or IEC 320 C19-C20 (16A) cables. The UPS is equipped with 8 IEC 320-C13 (10A)
sockets and 1 16A (IEC 320-C19) socket.
The UPS has two groups of output sockets: programmable sockets and fixed sockets.
It is recommended to connect critical loads to group 2 sockets, and less important loads to group 1
programmable sockets (see description 3.1.).
In the event of a power failure, you can extend the working time of critical loads (connected to the
group 2 sockets) on the battery by reducing the working time of devices connected to the
programmable sockets (group 1). Programming the working time of devices connected to the
programmable sockets is available from the level of the UPS configuration menu.
Do not connect devices to the UPS output that may overload it, e.g. laser printers, electric
heaters, heaters, etc.
Cables should be connected and placed in such a way that no one can accidentally
disconnect them.

3.6. Remote REPO switch connection
The UPS is equipped with an EPO port for connecting a remote REPO (Remote
Emergency Power Off) switch.
By default, the EPO port is configured as NC (normally closed), EPO is activated by
breaking the connection between Pin 1 and Pin 2 (jumper removed).
You can change the EPO configuration to NO (Normally Open) from the Setup
Menu on the LCD. Changing the configuration to NO requires removing the
jumper between Pin 1 and Pin 2.
3.7. 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 UPS to the USB port on the UPS on one end and the USB port on the computer on the other.
The software supplied with the UPS allows you to automate the processes of switching on/off the
receivers connected to the UPS depending on the events that occur on the UPS (e.g. power failure,
low battery charge, overload, etc.). The software also allows for ongoing monitoring of operation and
registration of the history of UPS events.
The UPS also has a slot for additional cards, which enables retrofitting with an SNMP network card for
remote communication via the Internet or an AS-400 relay contact card for communication with
external supervision systems, e.g. BMS.
Attention! RS-232 and USB port cannot be used simultaneously.
3.8. TVSS connection
In order to protect the data lines (Internet/fax/telephone) against
surges, the UPS is equipped with an additional TVSS filter. The protected
device should be connected to the sockets located on the rear panel of
the power supply, marked as in the figure beside.
