Configuring user settings
User settings can be configured via front panel. Select Settings from main menu and then select
User Settings.
Changing language
Pressing and holding down the first button on the left for about 3 seconds selects the language
menu. This action is possible from any LCD menu screen.
The default firmware has four main languages: English, Spanish, French and German. Other
local language packages including Chinese, Greek and Russian can be requested from the local
service representative.
Changing charging current
Maximum charging current setting should be checked when needed back-up time needs more
than 3 Amps charging current.
Table 35. Required battery charge currents.
Select Maximum charging current from User Settings menu. Default setting is 3.0 Amps and it is
changeable up to 20 Amps. Minimum step is 0.1 A.
Note!
Maximum charging current is dependent on output load and power rate of the
UPS. If the UPS is supporting maximum output load the highest level of Maximum
charging current is 3.0 A, which is also the default setting. As a thumb rule, 1 kW
decrease in the load provides extra 2.0 A charging capacity. For example, the
charging capacity is 5 Amps at 8 kW load, and 7 A at 7 kW load.
Using relay outputs
Relay outputs can be used for remote alarm indications.
Each relay has four standard pre-programmed settings for alarms:
• on bypass, UPS ok, battery low, on battery
One of the standard relay settings is “custom” that can be customised by the user.
The procedure to select customised alarms:
1. Push any key of the control panel to enable the functions on the LCD screen.
2. First select “SETTINGS”, then “USER SETTINGS” and finally “RELAY CONFIG” from the LCD menu.
3. Select the relay what is needed to be configured (ALARM-1 is fixed relay output X57).
4. Select “empty” to clear old settings.
5. Select “custom” and activate needed alarms with the button on the right.
6. After the selection press “OK” button
7. Finally test that UPS alarms correctly

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.
