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.
Audible Alarms and UPS Conditions
The UPS has an audible alarm feature to alert you of potential power problems. When the alarm is activated, the UPS beeps in different intervals according to a particular condition. Use Table 9 to determine and resolve the UPS alarms and conditions.
Silencing an Audible Alarm
To silence the alarm for an existing fault, press the 
button. If UPS status changes, the alarm beeps, overriding the previous alarm silencing. The alarm does not silence if there is a UPS fault, low battery condition, or if the battery needs to be replaced.
