Site Wiring Fault (120V Models Only)
The Site Wiring Fault indicator on the UPS rear panel illuminates if the
ground wire connection does not exist or the line and neutral wires are
reversed in the line receptacle. This indicator stays on until the condition
is resolved. Have a qualified electrician correct the wiring fault. The UPS
operates when the indicator is illuminated, but does not provide rated
noise and surge suppression.
