Troubleshooting
Consult APC Online Technical Support or call APC Technical Support for assistance with problems that cannot be resolved using the table below:
Problem Probable Cause Solution
Unit will not turn on.
Connected equipment loses power.
The power On button is lit and the unit is 
beeping four times every 30 seconds.
Battery is disconnected. 
Circuit Breaker has tripped.
Utility power not available at the wall outlet.
Equipment is connected to the “Surge Protection” outlets.
The unit is overloaded.
The unit has exhausted its available battery power.
Connected equipment does not accept the stepapproximated sine waveform the unit.
The unit may require service.
The unit is using battery.
Connect the battery (see Connect Battery). 
Reduce the amount of equipment plugged into the “Battery Backup + Surge 
Protection” outlets. Reset the Circuit Breaker by pushing it back in.
Reduce the amount of equipment plugged into the “Surge Protection” outlets. Reset 
the Circuit Breaker by pushing it back in.
Ensure that the fuse or circuit breaker for the outlet is okay, and that the wall switch 
controlling the outlet (if any) is in the ON position.
Ensure that the equipment you want to stay powered during a power failure is 
plugged into the “Battery Backup + Surge Protection” outlets and NOT the “Surge 
Protection” outlets.
Make sure that the equipment plugged into the outlets of the unit are not 
overloading the capacity of the unit. Try removing 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 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, the unit will recharge the battery. 
Allow the unit to charge by leaving it plugged into the wall a full 16 hours. 
As a battery ages, the amount of runtime available will decrease. You can replace 
the battery by ordering one at www.apc.com. Batteries also age prematurely if the 
unit is placed near excessive heat.
Safety
This section contains important instructions that should be followed during installation 
and maintenance of the APC equipment and batteries. It is intended for APC 
customers who setup, install, relocate, or maintain APC equipment.
This equipment is intended for installation in a temperature-controlled indoor area (see 
Specifications for exact temperature range), free of conductive contaminants.
Electrical Safety 
To reduce the risk of fire, connect only to a circuit provided with 20-amp
!
maximum branch circuit overcurrent protection in accordance with the 
National Electrical Code ANSI/NFPA.
CAUTION! De-energizing Safety
The unit has an internal energy source (the battery); the output may be energized
!
when the unit is not connected to an AC power outlet.
To de-energize pluggable equipment: switch the unit off. Disconnect the unit 
from utility power. Next, disconnect the equipment from the unit. Disconnect 
the internal battery (see Connect Battery).
The unit includes a protective earth conductor which carries the leakage 
current from the load devices (computer equipment). Total leakage current 
must not exceed 3.5 mA.
Use of the unit in life support applications where failure of the unit can 
reasonably be expected to cause the failure of the life support equipment or 
to significantly effect its safety or effectiveness is not recommended.
WARNING! Battery Safety
