Afterwards UPS starts to supply the loads.
Even all the fuses and breakers of the UPS are at “0” (OFF) position, still hazardous voltage
exist on connection terminals of the UPS. Therefore Do not touch the terminals.
If you work on terminals; all circuit breakers in the input/bypass distribution panel, and if any
the battery circuit breakers in the external battery cabinet, should be brought to “0” position.
