Active Alarms
Main Menu
→ Active Alarms
When an alarm sounds (and the red LED lights), from the Main Menu, scroll
to the active alarm count. “X” is the number of alarms detected. Press the
Enter button to step through the list of alarm descriptions. If more than 1
alarm was indicated, make sure to look at every alarm.
The alarms generated by this UPS are:
Input AC Over Voltage
If the utility voltage rises over the specified range, the UPS will buck the
output voltage down, and trigger a red LED alarm signal. An audible alarm
will be triggered when overvoltage reaches 120% of the nominal range setting.
X Alarms
Input AC Over Voltage
Input AC Under Voltage
If the utility voltage falls below the specified range (20% or more under
voltage), the UPS will boost the output voltage up and raise an alarm. This
alarm will not appear until the UPS is on battery.
X Alarms
Input AC Under Voltage
Input Over or Under Frequency
If the utility frequency suddenly changes, the UPS will raise an alarm. This
only occurs when the UPS goes on battery.
