Back-UPS
In compliance with Department of Transportation (DOT) regulations, the Back-UPS is shipped with the
internal red battery wire disconnected. The Back-UPS will not operate until the internal red wire is con-
nected to the battery. Once connected, allow the Back-UPS to charge for a full eight hours prior to use.
Note: Small sparks may occur during battery connection. This is normal.
b. Pull the battery about half way out, as shown
a.
Open the battery compartment, as shown.
c.
Connect the red battery wire to the positive
battery terminal.
d.
Push the battery into the battery compartment
and re-install the cover, as shown.
If the red Building Wiring Fault indicator on the
rear panel of the Back-UPS is lit, one of the
following conditions exists:
Open or high resistance ground
Hot or neutral polarity reversed
Overloaded neutral circuit
A lit indicator means that a potential shock
hazard exists. Improper building wiring should
be corrected by a qualified electrician. Do not
use the Back-UPS until the condition that caused
the fault is corrected.
Note: Improper building wiring will not prevent the
Back-UPS from operating, but it will limit its
protection capability. It may also result in
equipment damage that is not covered by the APC
Equipment Protection Policy.
The rear panel of the Back-UPS consists of the
following elements:
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.
Surge Only Outlets (qty. of 3). These outlets are
always On (when utility power is available) and
are not controlled by the On/Off switch. These
outlets do not provide power during a power
outage. Connect a printer, fax machine or scanner
to these outlets.
Black Velcro Straps (qty. of 2 - not shown). For
convenience, two velcro traps have been included
and can be used to manage power cords.

Press the push-button on the front panel of the
Back-UPS.
Observe that the following events occur after
pressing and releasing the push-button:
The green On-Line indicator flashes.
The yellow On Battery indicator lights while
the Self-Test is being performed.
When Self-Test has successfully completed,
only the green On Line indicator will be lit.
If the internal battery is not connected, (see
Step 1 above) the green On Line indicator and
red Replace Battery indicator will light. The
Back-UPS will also emit a chirping sound.

There are four status indicators (lights) on the front
panel of the Back-UPS (On Line, On Battery,
Overload, and Replace Battery).
On Line (green)
- is lit whenever utility power
is powering the Battery Backup outlets.

On Battery (yellow)
- is lit whenever the bat-

nected to the Battery Backup Outlets.
Four Beeps Every 30 Seconds - this
alarm is sounded whenever the Back-
UPS is running On Battery. Consider
saving work in progress.
Continuous Beeping - this alarm is
sounded whenever a low battery con-
dition is reached. Battery run-time is
very low. Promptly save any work in
progress and exit all open applica-
tions. Shutdown the operating system,
computer and the Back-UPS.
Overload (red)
- is lit whenever power demand
has exceeded the capacity of the Back-UPS.
Continuous Tone - this alarm is
sounded whenever the Battery Backup
outlets are overloaded.
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 dis-
connect itself from utility power. If the
button sticks out, disconnect non-essen-
tial equipment. Reset the circuit breaker
by pushing the button inward.

Plug the Back-UPS into a wall outlet, as shown.
The Back-UPS charges the internal battery
any time it is connected to a wall outlet.
The telephone ports provide lightning surge pro-
tection for any device connected to the telephone
line (computer, modem, fax or telephone). The
telephone ports are compatible with Home Phone-
line Networking Alliance (HPNA) and Digital
Suscriber Line (DSL) standards, as well as all
modem data rates. Connect as shown.

- is lit whenever the bat-
tery is near the end of its useful life, or if the bat-
tery is not connected (see above). A battery that is
near the end of its useful life has insufficient run-
time and should be replaced.

Transfer Voltage Adjustment (optional)
Install Software (optional)
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.

Back-UPS Storage
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 will not switch on
Back-UPS not connected to an AC
power source.
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 push-
ing 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.
Computer, monitor or external disk/
CD-ROM drive is plugged into a
Surge Only outlet.
Check the battery connections. (See Connect the Battery under
Installation on the front page of this document.
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.
The wall outlet that the Back-UPS is
connected to does not supply utility
power to the unit.
Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by push-
ing the circuit breaker button fully inward
until it catches.
Back-UPS does not provide expected backup time
Back-UPS is excessively loaded.
Back-UPS battery is weak due to
recent outage and has not had time
to recharge.
Battery requires replacement.
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 printer
