The UPS raises an alarm if the inverter function does not perform as expected.
X Alarms
Inverter Fault
Battery Low
The batteries are automatically charged by the UPS when it is connected to
utility voltage. Therefore, if this alarm is triggered while the UPS is on the
utility voltage, the battery test has failed and the batteries must be replaced.
Otherwise, it is a warning that the battery runtime is lowa 60-day warning.
X Alarms
Battery Low
Utility Not Present
When the utility voltage cuts off, the UPS sounds an alarm. The Battery LED
(the left yellow LED) will light, indicating the switch to battery power. Check
the utility voltage connection.
X Alarms
Utility Not Present
Battery Totally Discharged
This means there is no charge left in the battery, and the UPS can no longer
power its loads. The batteries must be recharged for 24 hours before further
use. If this alarm occurs when the UPS is not on battery power, the battery
needs to be replaced.
