Problem Probable Cause Solution
Ensure that the fuse or circuit breaker for the wall outlet is okay, and that the wall
switch controlling the wall outlet (if any) is in the ON position. Ensure the battery
has been fully charged.
Reduce the amount of equipment plugged into the “Battery Backup + Surge
Protection” outlets. Reset the Circuit Breaker by pushing it back in.
Ensure the equipment plugged into the outlets of the unit are not overloading the
capacity of the unit. Try disconnecting some of the equipment and see if the
problem continues.
The unit can only operate on battery power for a limited amount of time. The unit
will eventually turn off when the available battery power has been used. Allow the
unit to recharge for 16 hours before continuing use of the unit.
The output waveform is designed for computers and computer-related equipment.
It is not designed for use with motor-type equipment.
Contact APC Technical Support for further troubleshooting.
The unit is operating normally and supplying battery power. Once On Battery, you
should save your current work, power down your equipment, and turn the unit OFF.
Once normal power is restored, you may turn the unit back ON and power your
equipment.
The unit is about to shut off due to a low battery charge condition! When the unit
beeps once every second, the battery has about 2 minutes of power remaining.
Immediately power down your computer and turn the unit OFF. When normal
power returns, you may turn the unit back ON; the unit will recharge the battery.
Allow the unit to charge by leaving it plugged in and switched on for 16 hours.
As a battery ages, the amount of runtime available will decrease. Batteries also age
prematurely if the unit is placed near excessive heat. If the battery will not charge,
the Back-UPS is no longer operable.
