Back-UPS
The rear panel of the Back-UPS consists of the
following elements:
Note: Allow the Back-UPS to charge for a full eight
hours prior to use.
Battery Back Up Outlets (qty. of 3). These
outlets provide battery back-up, surge protection,
and Electro-magnetic Interference (EMI) filtering.
In case of power outage, battery power is
automatically provided to these outlets. Power
(utility or battery) is not supplied to these outlets
when the Back-UPS is switched Off. Connect a
computer, monitor, and external disk or CD-ROM
drive to these outlets.
Press the push-button on Back-UPS front panel.

Status Indicators and Alarms
There are four status indicators (lights) on the front
panel of the Back-UPS (On Line, On Battery,
Overload, and Replace Battery).
Replace the Internal Battery
Overload (red) - is lit whenever
power demand has exceeded
capacity of the Back-UPS.
To replace the internal battery, proceed as follows:

Note:
Replacing the battery is a safe procedure. However, small sparks may occur
during the process. This is normal.

sounded whenever the Battery Backup
outlets are overloaded.

Four Beeps Every 30 Seconds - this
alarm is sounded whenever the BackUPS is running On Battery. Consider
saving work in progress.
Continuous Beeping - this alarm is
sounded whenever a low battery
condition is reached. Battery run-time is
very low. Promptly save any work in
progress and exit all open applications.

Circuit Breaker - the circuit
breaker button located on the rear
panel of the Back-UPS will stick
out if an overload condition forces
the Back-UPS to disconnect itself
from utility power. If the button
sticks out, disconnect nonessential equipment. Reset the
circuit breaker by pushing the
button inward.
Replace Battery (red) - is lit whenever the battery is near the end of its useful life, or if the battery is not connected
(see above). A battery that is near the
end of its useful life has insufficient runtime and should be replaced.
Chirps for 1 Minute Every 5 Hours this alarm is sounded whenever the
battery has failed the automatic
diagnostic test.

Transfer Voltage Adjustment (optional)
Order Replacement Battery
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 Lower Transfer Voltage, as shown in the following table.
The typical battery lifetime is 3-6 years (depending on the number of discharge cycles and operating
temperature). A replacement battery can be ordered over the phone from APC, or the battery can be ordered
on-line from the APC web site (see below, a valid credit card is required).

Troubleshooting
Specifications
Use the tables below to solve minor Back-UPS installation and operation problems. Consult APC On-line
Technical Support or call APC Technical Support for assistance with problems that cannot be resolved using
this document:
Possible Cause
Procedure
Back-UPS circuit breaker “tripped”.
Very low or no utility voltage.
Check that the Back-UPS power plug is
securely connected to the wall outlet.
Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by
pushing the circuit breaker button fully
inward until it catches. If the circuit breaker
resets, switch the Back-UPS on and reconnect
the equipment one-at-a-time. If the circuit
breaker trips again, it is likely that one of the
connected devices is causing the overload.
Check the wall outlet that supplies power to
the Back-UPS using a table lamp. If the lamp
bulb is very dim, have the utility voltage
checked by a qualified electrician.
Back-UPS does not power computer/monitor/external drive during an outage
Internal battery is not connected.
Check the battery connections. (See “Connect the Battery” under
“Installation” on the front page of this document.
Computer, monitor or external disk/
CD-ROM drive is plugged into a
Surge Only outlet.
Move computer, monitor, or external drive power cord plug to the
Battery Backup outlets.
Back-UPS operates on battery although normal utility voltage exists
Back-UPS circuit breaker “tripped”.
Frequency Limits (on line)
Stepped Sine Wave
Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by
pushing the circuit breaker button fully
inward until it catches.
Unplug non-essential Battery Backup connected equipment, such as
printers and plug them into Surge Only outlets.
Note: Devices that have motors or dimmer switches (laser printers,
heaters, fans, lamps, and vacuum cleaners, for example) should not be
connected to the Battery Backup outlets.
Back-UPS battery is weak due to
recent outage and has not had time
to recharge.
Charge the battery. The battery charges whenever the Back-UPS is
connected to a wall outlet. Typically, eight hours of charging time are
needed to fully charge the battery from total discharge. Back-UPS
run-time is reduced until the battery is fully charged.
Battery requires replacement.
Replace battery (see Order Replacement Battery). Batteries typically
last 3-6 years, shorter if subjected to frequent power outages or
elevated temperatures.
A red indicator is lit
Battery is not connected properly.
Check the battery connections. Consult "Connect the Battery" under
"Installation" on the front page of this document. It shows how to
access the battery and connect the wires.
The Overload indicator is lit if
equipment connected to the Battery
Backup outlets is drawing more
power than the Back-UPS can
provide.
Move one or more equipment power plugs to the Surge Only outlets.
Battery requires replacement.
The battery should be replaced within two weeks (see "Order
Replacement Battery"). Failure to replace the battery will result in
reduced run-time during a power outage.
Red indicators are flashing
Call APC for service.

Service
Note: If the UPS requires service, do not return it to the dealer. The following steps
should be taken:
1.
2.
Consult the Troubleshooting section to eliminate common problems.
Determine if the circuit breaker is tripped. If the circuit breaker is tripped, reset the breaker and
determine if the problem still exists.
If the problem persists, consult the APC Worldwide Web site (www.apcc.com) or call customer
service.
•
Record the model number of the UPS, the serial number, and the date purchased. Be prepared
to troubleshoot the problem over the telephone with a technician. If this is not successful, the
technician will issue a Return Merchandise Authorization Number (RMA#) and a shipping
address.
•
If the UPS is under warranty, repairs are free. If not, there is a repair charge.
Pack the UPS in its original packaging. If the original packing is not available, ask customer
service about obtaining a new set. Pack the UPS properly to avoid damage in transit.

Return the UPS by insured, prepaid carrier to the address provided by customer service.
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 assigned 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 to the customer.
