The Low Battery Alarm
does not give enough
warning.
The batteries need charging or
service.
Plug the UPS into a wall outlet for 24 hours to charge the
battery. After charging the battery, press and hold the
button for 3 seconds; then check the Battery Service
indicator.
If the Battery Service indicator is still on, see “UPS
Maintenance” on page 19 to replace the battery.
The Low Battery Alarm is not
set appropriately.
Change the alarm setting. See “Configuration Mode” on
page 15.
AC input high
The AC input voltage is too
high. The UPS is running on
battery power.
Correct the input voltage, if possible. The UPS continues to
operate on battery until the battery is completely discharged.
If the condition persists, the input voltage in your area may
differ from the UPS nominal. Change the UPS input voltage to
match your local voltage (see “Configuration Mode” on
page 15).
AC input low
The line voltage is too low. The
UPS is running on battery
power.
Correct the input voltage, if possible. The UPS continues to
operate on battery until the battery is completely discharged.
If the condition persists, the input voltage in your area may
differ from the UPS nominal. Change the UPS input voltage to
match your local voltage (see “Configuration Mode” on
page 15).
Site Wiring Fault
Ground wire connection does
not exist in the wall outlet or
the line and neutral wires are
