Silencing an Audible Alarm
Before silencing an alarm, check the alarm condition and perform the applicable action
to resolve the condition (see Table 10).
To silence the alarm for an existing fault, press the (Test/Alarm Reset) button. If UPS
status changes, the UPS 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.
Site Wiring Fault (100–120V 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.
