Troubleshooting
Use the table below to solve minor Back-UPS ES installation or operation problems. Consult APC Online Technical Support or call APC
Technical Support for assistance with problems that cannot be resolved using the table below:
Back-UPS ES will not turn on.
No power available at the Surge Protection
outlets.
Connected equipment loses power.
The Power On indicator is lit and the Back-
UPS ES is beeping four times every 30
seconds.
The Power On indicator flashes once per
second and the Back-UPS ES beeps once
per second at the same time.
Building Wiring Fault indicator is lit.
Inadequate runtime.
Battery is disconnected and utility power is not available at
the wall outlet.
Surge Protection outlets have been overloaded.
Utility power not available at the wall outlet.
Equipment is connected to the “Surge Protection” outlets.
The Back-UPS ES is overloaded.
PowerChute Personal Edition software has performed a
shutdown due to a power failure.
The Back-UPS ES has exhausted its available battery
power.
Connected equipment does not accept the step-
approximated sine waveform the Back-UPS ES.
The Back-UPS ES may require service.
The Back-UPS ES is using battery.
Battery capacity is low (about 2 minutes of use remaining).
Your building wiring presents a shock hazard. Using the
Back-UPS with this condition will void the warranty.
The battery is not fully charged.
Battery is near the end of useful life.
Connect the battery (see Connect Battery) and ensure power is available at the wall
outlet.
Reduce the amount of equipment plugged into Surge Protection outlets.
Ensure that the fuse or circuit breaker for the outlet is not tripped, 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 plus 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 Back-UPS ES is operating normally.
The Back-UPS ES 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 Back-UPS ES is operating normally and using 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 Back-UPS ES 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.
Call a qualified electrician for service.
Allow the unit to charge by leaving it plugged into the wall at least 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
Back-UPS ES is placed near excessive heat.

department or cross-ship upon the provision of a valid credit card number. The
customer pays for shipping to APC, and APC pays ground freight transportation costs
back to the customer.
