2. Insert the external battery fuses on each unit.
In case of GE battery cabinet:
DANGER !
Before to perform this operation, check the right DC polarities on both side of the
switch/fuse holder!
3. Close the output switch Q1 (Pos. I) on all UPS units.
When the last Q1 will be closed the output will be supplied by the
mains through all automatic bypass.
The synoptic diagram, on all UPS units, must display the status
"LOAD SUPPLIED BY AUTOMATIC BYPASS".
Verify on all UPS units, selecting the screen METERING/BOOSTER/Vp
and Vn, that the booster voltage has reached about 400 Vdc.
4. Insert the inverter by pressing "Inverter ON" ( I ) key on first UPS unit.
In case of sufficient output power, the output will transfer to
Inverter.
LED Alarm turn Off and the LED Operation must be is lit.
The synoptic diagram, on first UPS unit, must display the status

LED Alarm turn Off and the LED Operation must be lit.
The synoptic diagram, on all UPS units, must display the status
"LOAD SUPPLIED BY INVERTER".
6. Load supply.
LP 33 Series Parallel System is now running, supplying power to the output.
Insert the loads one by one to the output of the LP 33 Series Parallel System.
Check the output current value of L1, L2 and L3 and check for correct load balance.
NOTE !
Even if the UPS is delivered with the battery fully charged, they could be partially
discharged during transportation or storage.
It is recommended to recharge the battery during at least 10 hours in order to
provide the complete battery energy stored to the load in the event of mains failure.
