UPS not connected to utility
power supply. Check that the power cord from the UPS to the utility power supply is se-
curely connected at both ends.
Battery not connected prop-
erly. Ensure that the battery is properly connected.

ity power irregularities.
UPS IS NOT PROVIDING EXPECTED BACKUP TIME
The UPS battery is weak due
to a recent outage or is near
the end of the service life.
Charge the battery. Batteries require recharging after extended outages, and
wear faster when frequently put into service or when operated at elevated
temperatures. If the battery is near the end of the service life, consider re-
placing even if the replace battery LED is not yet illuminated.
ON-LINE AND OVERLOAD LEDS ARE FLASHING ALTERNATELY
The UPS was shut down
through PowerChute. None. The UPS will restart when utility power returns.
ON-LINE AND ON-BATTERY LEDS ARE FLASHING, OR, OVERLOAD LED IS FLASHING

has shut down. Do not attempt to use the UPS. Turn off the UPS, unplug the battery, and
have it serviced immediately.
ALL LEDS ARE OFF AND THE UPS IS PLUGGED INTO A WALL OUTLET
The UPS is shut down or the
battery is discharged from an
extended outage.
