Troubleshooting
Silencing an Audible AlarmBefore silencing an alarm, check the alarm condition and perform the applicable action to resolve the condition (see Table 8). To silence the alarm for an existing fault, press the 
button. If UPS status changes, the alarm beeps, overriding the previous alarm silencing.
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.
