5.1 UPS Switch on Procedures 10 to 30kVA
The following stages have to be carried out chronologically. If alarms are displayed on the mimic-
panel, the problem has to be solved before going any further.
1. Open the UPS doors to gain access to the main power switches.
2. Make sure that the S3 switch (maintenance bypass) is in “ 0 ” (OFF) position.
3. Turn on the rectifier input fuses (F1-F2-F3) and inverter input switch S1 , by bringing them into
“ 1 ” (ON) position. (Upwards)
4. Turn on the static by-pass switch S2 into “ 1 ” (ON) position.
5. Turn on the S4 fuse/switch (UPS output), into ” 1 ” (ON) position.
RECTIFIER START!
: Rectifier is working and static bypass continues to feed the load.
INVERTER START! : Inverter is working and static bypass continues to feed the load.
STATUS NORMAL! : The UPS is operating normally, its inverter supplying the outlet.
6. Turn on the BATT.(+) and BATT.(-) fuses into “ 1 ” (ON) position. By this way it is ensured to
connect the battery group to the UPS.
7. Your UPS system is ready to use. You can start up your load.
ATTENTION: At this stage, the load is supplied by the inverter.
5.2 UPS Switch on Procedures 40 to 200kVA
1)
Make sure that all the switches and fuses (S1, S2, S3, S4 and S5) are in “OFF” position and S6
is in “NORMAL” position.
NOTE THAT S6 SHOULD ALWAYS BE IN “NORMAL” POSITION FOR ONLINE OPERATION
2)
Turn S2 switch (static bypass) into “1” (ON) position.
3)
Turn on S4 (output switch), now the load is connected to bypass supply.
4)
Turn on the S1 switch (inverter input), into ”1” position. By turning on S1, all lights on the front
panel will be lit for 4 secs (lamp test) and then, the following messages will appear on LCD.
“RECTIFIER START” : Rectifier is operating and static bypass continues to supply the load.
“INVERTER START”: Inverter is operating and static bypass continues to supply the load.
“STATUS NORMAL” : The UPS is operating normally and the inverter is supplying the load.
ATTENTION : AC output voltage is applied to the load at this step.
