5.9 UPS Shutdown Procedures 40 to 200kVA
All the power switches, isolators and circuit breakers should be turned off, with the following
sequence. (Turn off into “
0 ” (OFF) position). There will be no voltage on the load.
WARNING!!! This procedure will cut the energy of all the equipments that are connected to UPS
output.
S4 (UPS output)
S2 (static by-pass)
S1 (inverter input)
S5 (Battery circuit breaker or battery fuse)
5.10 Utility Interruption
When there is a utility power interruption, the inverter led continuously lit also battery and on the
LCD
“A10 LINE FAILURE” message appears. Additionally an audible alarm sounds. Your UPS
continues to convert the battery voltage to AC voltage and protect against loss of data and failure.
The autonomy can be increased by disconnecting relatively unimportant loads. But do not connect
this load again before the end of autonomy time. When the utility power is restored the UPS will
return to normal operation and on the front panel of the UPS
“A45 MAINS OK” mesage appears.
When there is “ A7 BATTERY LOW ” message appears and audible alarm sounds, shut down your
PC. If not, than all the batteries will be discharge in a few minutes.
After you shut down the critical load (computer system). Apply the completely powering down the
UPS.
Apply the normal operation procedure to start up the UPS again after a long time later.
NOTE: Do not forget to turn on the battery circuit breaker into “1” (ON) position when
the mains voltage return. If not, in case of a second power cut there will be no voltage for
the critical load.
If you have a reserve generator, you can use it to feed the UPS’s input and the batteries
starts to charge. By using UPS and the generator at the same time ensures to charge the
batteries faster.
