Switch On the
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
connected 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.
a. Open the battery compartment, as shown.
b. Pull the battery about half way out, 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.
• This UPS is intended for indoor use only.
• Do not operate this UPS in direct sunlight, in
contact with fluids, or where there is excessive
dust or humidity.
• Be sure the air vents on the UPS are not blocked.
Allow adequate space for proper ventilation.
• The battery typically lasts for two to three years.
Environmental factors impact battery life. Elevated
ambient temperatures, poor quality AC power, and
frequent short duration discharges will shorten
battery life.
• Connect the UPS power cable directly to a wall
outlet. Do not use surge protectors or extension
cords.
Plug the Back-UPS into a wall outlet, 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
by Schneider Electric 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
(AC 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.

Note: Allow the Back-UPS to charge for a full eight
hours prior to use.
Press the push-button on the front panel of the
Back-UPS.
Observe that the following events occur after press-
ing 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 AC power is
powering the Battery Backup outlets.
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 disconnect itself
from AC power. If the button
sticks out, disconnect non-
essential equipment. Reset the
circuit breaker by pushing the
button inward.

Connect the Phone
Line to Surge Protection
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
Subscriber Line (DSL) standards, as well as all
modem data rates. Connect as shown.
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 run-time and should be replaced.
Chirps for 1 Minute Every 5
Hours - this alarm is sounded
whenever the battery has failed the
automatic diagnostic test.

Status Indicators and Alarms
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 push button. To
adjust the transfer voltage, proceed as follows:
1.Plug the Back-UPS into the AC power source. The Back-UPS will be in a Standby Mode (no indicators
lit).
2.Press the front panel push button 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 push button until the yellow indicator is flashing.
5.To select the Medium Sensitivity setting, press the push button until the yellow and red indicators (second
and third from the top) are flashing.
6.To select the High Sensitivity setting, press the push button until yellow and both red indicators (bottom
three) are flashing.
7.To exit without changing the Sensitivity Setting, press the push button until the green indicator is flashing.
8.Once in Programming Mode, if the push button is not pressed within 5 seconds, the Back-UPS will exit
Programming Mode; all indicators will extinguish.
