TROUBLESHOOTING
Problem
 Possible Cause
Corrective Action
Back-UPS will not switch on.
Back-UPS not connected to AC power source. 
Ensure the Back-UPS is securely connected to an AC outlet.
Back-UPS circuit breaker “tripped”. 
Disconnect non-essential equipment from the Back-UPS. Reset
(push in) the rear panel circuit breaker. Switch on the Back-UPS
and plug in devices one at a time. If the circuit breaker trips
again, disconnect the device that caused the breaker to trip.
Utility input voltage quality is out of range.
Consider adjusting the transfer voltage and sensitivity. See
Transfer Voltage and Sensitivity Adjustment.
Internal battery cartridge is not connected.
Connect battery cartridge (see Connect Battery Cartridge).
Back-UPS does not power 
essential equipment during an 
outage. 
Equipment plugged into a Surge Only outlet. 
Unplug device from 'Surge Only' outlet and move to a 'Battery
Backup' outlet.
Back-UPS operates on battery 
although utility power exists.
Back-UPS circuit breaker “tripped”. 
Disconnect non-essential equipment from the Back-UPS. Reset
(push in) the rear panel circuit breaker. Switch the Back-UPS on
and plug equipment in one-at-a-time. If the circuit breaker trips
again, disconnect the device that caused the breaker to trip.
Utility input voltage quality is out of range.
Consider adjusting the transfer voltage and sensitivity. See
Transfer Voltage and Sensitivity Adjustment.
Back-UPS does not provide 
expected backup time.
Back-UPS is heavily loaded. 
Unplug non-essential equipment (printers, scanners, etc) from
the Battery Backup outlets and plug into 'Surge Only' outlets.
Back-UPS battery cartridge is discharged due to 
recent power outage and has not had time to 
recharge. 
Charge the battery cartridge for 8 hours. Back-UPS runtime is
reduced until the battery cartridge is fully charged.
 
Battery has reached the end of its life.
Replace  battery  cartridge  (see  Order Replacement Battery
Cartridge).
Red Replace Battery indicator is 
flashing. Green On Line indicator 
is on.
Internal battery cartridge is not connected.
Connect battery cartridge (see Connect Battery Cartridge).
Red Replace Battery indicator is 
on.
Battery has reached the end of its life.
Replace  the  battery  cartridge  (see  Order  Replacement Battery
Cartridge).
Red Overload indicator is on or 
flashing.
Connected equipment is drawing more power than 
the Back-UPS can provide.
Move one or more equipment power plugs from Battery Backup
outlets to Surge Only outlets.
Green On Line indicator is on and 
all other front panel indicators are 
flashing.
Internal UPS fault.
Contact APC Technical Support (see Contact Information).
SERVICE
If the Back-UPS arrived damaged, notify the carrier.
If the Back-UPS requires service, do not return it to the dealer. The following
steps should be taken:
1.
Consult the Troubleshooting section to eliminate common problems.
2.
If the problem persists, go to http://www.apc.com/support/.
3.
If the problem still persists, contact APC Technical Support.
4.
Have the Back-UPS model number, serial number and date of purchase
available. Be prepared to troubleshoot the problem with an APC Technical
Support representative. If this is not successful, APC will issue a Return
Merchandise Authorization (RMA) number and a shipping address.

LIMITED WARRANTY
The standard warranty is two (2) years from the date of purchase. APC’s standard
procedure is to replace the original unit with a factory reconditioned unit.
Customers who must have the original unit back due to the assignment of asset
tags and set depreciation schedules must declare such a need at first contact with
an APC Technical Support representative. APC will ship the replacement unit
once the defective unit has been received by the repair department, or cross-ship
upon the receipt of a valid credit card number. The customer pays for shipping the
unit to APC. APC pays ground freight transportation costs to ship the replacement
unit to the customer.
TRANSFER VOLTAGE AND SENSITIVITY
ORDER REPLACEMENT BATTERY CARTRIDGE
The battery cartridge typically lasts 3-6 years, shorter if subjected to frequent outages or elevated temperatures. Order part number RBC32.
Please recycle spent battery cartridges.

In situations where the Back-UPS or connected equipment appears too sensitive
to input voltage, it may be necessary to adjust the transfer voltage. This is a
simple task requiring use of the front panel pushbutton. To adjust the transfer
voltage, proceed as follows:
1. Plug the Back-UPS into the utility power source. The Back-UPS will be in a
Standby Mode (no indicators lit).
2. Press the front panel pushbutton fully inward for 10 seconds. All indicators
on the Back-UPS will flash to acknowledge going into Programming Mode.
3. The Back-UPS will then indicate its current Sensitivity Setting, as shown in
the following table.
4. To select the Low Sensitivity setting, press the pushbutton until the yellow
indicator is flashing.
5. To select the Medium Sensitivity setting, press the pushbutton until the
yellow and red indicators (second and third from the top) are flashing.
6. To select the High Sensitivity setting, press the pushbutton until yellow and
both red indicators (bottom three) are flashing.
7. To exit without changing the Sensitivity Setting, press the pushbutton until
the green indicator is flashing.
8. Once in Programming Mode, if the pushbutton is not pressed within 5
seconds, the Back-UPS will exit Programming Mode; all indicators will
extinguish.
