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.

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.
