Normal start-up
Check the mechanical and electrical installation of the UPS before start-up. Go through the
checklist below together with another person.
Check
Read the attached safety manual before you work on the unit.
The unit is fixed according to mechanical installation
The ambient conditions are within specification.
The cooling air will flow freely.
The UPS is grounded properly.
The input and bypass voltages match the UPS nominal voltage.
The input, bypass, battery and output terminal connections are OK.
Appropriate input and bypass fuses and disconnectors are installed.
Appropriate backfeed warning sign for disconnectors are installed.
Appropriate cables sizes are used.
The external control connections inside the UPS are OK.
There are no tools, foreign objects or dust inside the UPS from the installation.
Covers are in place.
Optional MBS is placed to UPS position as default.
You are then ready to proceed with the starting up the UPS:
1. Turn the battery and input circuit breakers to ON position.
2. UPS will enter a stand-by mode and starts to charge batteries with a cooling fan
operational. Output is without the voltage in the stand-by mode.
3. Push any key of the control panel to enable the functions of the LCD screen
4. Select “TURN UPS ON” from the LCD menu (see: Display Functions)
5. Press and hold
↵ button for 2 sec. There shall be no sound during the hold.
The UPS shall check its internal functions, synchronise to bypass and start to supply the load.
The green LED is blinking if there occurs an active notice. In normal operation the green LED is
constantly lit if no new active notice such as ‘unsyncronised’ or similar notices present.
The output voltage shall be verified from the output measurements screen of the LCD. If there is
voltage in the output then UPS is supplying the load.
Battery start-up
UPS will start on battery if mains is not available. Note that the UPS behavior may be slightly
different from the normal start-ups.
Start-up after EPO
1. Find out the reason that caused EPO
2. Check that there are no risk to start the UPS again
3. Follow Normal start-up check list and procedure

Shutdown
The procedure to shutdown from LCD is following:
1. Push any key of the control panel to enable the functions of the LCD screen
2. Select “TURN UPS OFF” from the LCD menu (see: Display Functions)
3. Press and hold ↵ button for 5 sec. There shall be an indication sound during the hold.
4. UPS shall do a shutdown routine.
5. Turn the battery and input circuit breakers to OFF position to finalise the shutdown procedure.
Note!
The behaviour is different if UPS is turned off from the programmable input or
through communication cards. If battery and input circuit breakers are left ON,
UPS will enter a stand-by mode and starts to charge batteries with a cooling fan
operational. Output is without the voltage in the stand-by mode.

8. Maintenance
All operations inside the unit must be performed only by a service engineer from the
manufacturer or from an agent, authorised by the manufacturer.
The troubleshooting procedure gives simple remedial if a malfunction occurs in the UPS.
The operator should start the trouble shooting if there is an active alarm indicated on the LCD
screen. Service should be contacted if the active alarm is abnormal and displayed as a service
code.
Call service if you are not able to solve the problem.
Table 36. Typical alarms displayed in the LCD screen of the UPS unit.
Regular service/intervals
The UPS requires very little maintenance if installed in an appropriate environment. In order
to ensure maximum availability of the UPS, manufacturer recommends signing a proactive
service agreement with a local authorised service provider.
Table 37. Routine maintenance intervals recommended by the manufacturer.
Batteries
The condition of the batteries is crucial for operation. The UPS will indicate by audible and
visual alarms if the capacity of the battery bank has decreased. The UPS units are provided
with the automatic battery test and ABM management function to continuously monitor the
condition of the battery bank.
Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and required precautions. When replacing batteries, replace with the same type and
number of batteries.
LCD display Description Action
Overload
The connected load needs more power
than the UPS is rated to provide. The
inverter or static bypass is supplying the
excessive load level.
Shut down the least important load that
is connected to the UPS. The UPS should
switch back to normal operation once the
load level is acceptable.
Battery test failed Your batteries are detected to be faulty.
Batteries should be replaced and you need
to contact the local office or representative
of the UPS manufacturer.
Battery low
The UPS is operating in stored energy
mode. It will shut down soon due to low
battery voltage.
Make controlled shutdown of the protected
load immediately to prevent loss of data.
On battery
The UPS is operating in stored energy
mode.
Save your data and perform a controlled
shutdown of your server load.
Overtemperature High UPS temperature is detected.
Check that fans are operational and ventila-
tion holes are not blocked. Make sure the
ambient temperature is not excessive
Maintentenance Interval
Batteries change ~ 3-5 years / service
Batteries test ~ 18 months / service
Cooling fan change ~ 5 years / service
