•Keep this user manual! It contains important information regarding the operations of UPS which
which should be used during installation and maintenance of the UPS and batteries.
•If the power supply is cold and will be moved to a warm room, condensation may occur. Therefore,
you should wait at least 2 hours until its launch.
•To reduce the risk of electric shock, the UPS should be installed in a room free of contaminants at
the right temperature and humidity. The ambient temperature must not exceed 40°C.
•Do not connect to the UPS output devices, which can cause it to overload, eg. Laser printers,
electric heaters, etc..
•Cables should be connected and positioned in such a way that no one has the possibility of
accidentally occur, or disconnected.
•The UPS must be connected to the wall socket with the proper protective conductor (PE).
•Do not block ventilation openings in the UPS. Make sure that the ventilation holes are discovered
and there is a minimum of 25cm of free space for free ventilation.
•Power supply socket UPS should be protected by an appropriate switch or circuit breaker.
•The UPS has its own power source of the battery, so sockets output voltage may be present,
although the UPS is not connected to the network.
•Support the battery should be performed by trained personnel who are knowledgeable about the
battery life and retain appropriate precautions during their use.
•When replacing the batteries, use batteries of the same amount and with the same parameters,
ie. Nominal voltage, capacity and dimensions.
WARNING! Do not dispose of batteries in a fire. The battery may explode.
WARNING! Do not open or damage batteries. Released electrolyte is harmful to skin
and eyes. It may be toxic.
•A battery can present a risk of electric shock. When working with batteries, take the following
precautions:
oRemove from the hand of watches, rings and other metal objects.
oWear rubber gloves and boots.
oDo not lay tools or metal parts on the battery.
oDisconnect the source for charging the battery before connecting or disconnecting battery
terminals.
•Make sure the battery is not accidentally grounded. If present, remove the source of ground fault.
Contact with any part of a grounded battery can result in electrical shock.

2. Transport, unpacking UPS
Check carefully that the carton and the contents are not damaged. If any damage is found,
immediately notify the shipping company and distributor of power supply.
Do not dispose carton of UPS.
1. If there was not any damage carefully open the carton.
2. Extract all the protective elements (sponges, fillers).
3. Gently remove the UPS from the protective film and place it on a clean, flat, stable surface.
The UPS should be transported only in the original packaging to prevent damage to
mechanical shocks and impacts.
2.1. Rack 19’’ Installation

Make sure that between the UPS and the battery module is mounted battery breaker.
Before connecting the battery module and the breaker UPS must be OFF.
3.2. Connection of external batteries
Connect one end of the battery into the corresponding slot on the rear panel of the UPS,
the other end of the slot located on the battery unit. In the case of a larger number of modules
the battery, the remaining connections are made between the battery modules provided as shown
below.
If you need to extend the autonomy, the power supply has the ability to connect batteries
a much larger capacity, by fitting him with an adjustable Charger with capacity 4A.
Setting the maximum charging current of the battery is made by authorized service of COVER UPSes.
In the case of the external battery of greater capacity, arranged for
racks or cabinets, pay special attention to the installation of additional
switch on a battery and the correct polarity of the wires connected from
batteries to the UPS. Incorrect wiring "+" and "-" may cause
permanent damage to the UPS.

CSA-2050.01
3.3. Connection of input and output
UPS CORE 6K and 10K is designed for permanent connection via terminal
which is localized on the rear side of UPS, as shown below.
UPS suitable for installation in single-phase three-wire,
TN with grounded neutral.
The UPS must be connected to a separate electrical system, made in accordance with the applicable
in the national rules and regulations. Input circuit UPS should be protected switch
over-current or fuse-element of the required recommendations in the current response.
On the input side of the UPS is not recommended to use a residual current device.
The cables should be connected and arranged in such a way that no one have the
possibility of their accidental disconnection.
3.4. Remote EPO connection
UPS has a EPO port for connecting the remote REPO switch (Remote Emergency Power
Off). Normally
EPO port is configured as a normally closed (NC), activation EPO takes place by
interrupting the connection between Pin 1 and Pin 2 (removal jumper). You can change
the configuration of EPO to NO (normally open) with level settings menu on the LCD.
Changing the configuration to NO It makes it necessary to remove the jumper between
pin 1 and pin 2.

computer. Supplied with the UPS software allows you to automate processes on / off
receivers connected to the power supply depending on the events that occur on the UPS
(Eg. Power failure, low battery, overload, etc.).
The software allows also for current monitoring and recording the history of the event UPS.
UPS also has a slot for an additional card, which allows retrofitting adapter SNMP
for remote communication via the Internet or a card of the relay contacts AS-400 to communicate
with external surveillance systems for example. BMS.
Warning! RS-232 and USB can not be used together.

mode
Description
Sceen status
Online mode
If the voltage is within the tolerance limits,
the UPS supplies applications directly from
the network. In this mode, after the battery
is fully charged the fans are turned off in
order to improve the efficiency of operation
Eco mode
Eco mode
If the supply voltage is within the tolerance
limits, the supply voltage is supplied directly
to the output of the UPS. The inverter is in
stand-by mode, which increases the
efficiency and reduce operating costs.
CVCF mode
If the frequency of the supply voltage is
within the 46 ÷ 64Hz, there the ability to set
a fixed value output frequency of 50 or
60Hz.
In this mode, the batteries are charged.
Battery mode
In the event of a power failure or when the
supply voltage is beyond the tolerance
allowing the output voltage to be kept
within the required tolerance, the UPS
switches to battery operation. The beep
sounds every 4 seconds.
Bypass mode
If the supply voltage is within acceptable
tolerance limits, but there is
overload or any other event that UPS will
switch to Bypass. A beep is issued every 2
minutes.
Battery test
Press half a second key "Test" in the course,
when the UPS is operating in normal or
frequency converter will force a battery
test.
Alarm
In safe mode, the UPS indicates an error
code, and icons allocated for the event.
