Electrical Preparations
CAUTION:
Before connecting any input wiring to the UPS, take precautions to ensure that all cir-
cuits being used are the proper voltage and current required for the UPS.
CAUTION:
UPS output receptacles are energized when the UPS is connected to the mains and the
bypass is enabled.
CAUTION:
Electrical shock hazard. Even when the UPS is disconnected from the mains, hazardous
voltages may still exist at the output receptacles of the UPS. The UPS receives power from more than
one source - AC input and DC input from batteries. All input sources (AC and DC) must be discon
nected before carrying out maintenance work inside the UPS.
