checked.If the UPS finds a problem,the

Site Wiring Fault

The Site Wiring Fault alarm is disabled by default and is only needed for

installations with a grounded-neutral electrical system. You can enable

the alarm throughthe System Setup menu on the front panel (see

page 42).

The Site Wiring Fault alarm detects a ground wire connection that does

not exist or reversed line and neutral wires in the line receptacle. If the

condition is detected during startup, the UPS does not supply power to

your equipment. If the condition is detected during Normal mode, the

UPS alarm beeps and the

indicator flashes. Have a qualified

electrician correct the wiring fault.
