Status Indicators
Troubleshooting
Voltage Sensitivity Adjustment (optional)
The Back-UPS detects and reacts to line voltage distortions by transferring to battery
backup power to protect connected equipment. In situations where either the Back-UPS
or the connected equipment is too sensitive for the input voltage level it is necessary to
adjust the transfer voltage.
1. Connect the Back-UPS to a wall outlet. The Back-UPS will be in Standby mode, no
indicators will be illuminated.
2. Press and hold the button for 10 seconds. The ON/OFF OnLine LED will illuminate
alternately green-amber-red, to indicate that the Back-UPS is in Program mode.
3. The Power On/Replace Battery LED will flash either green, amber, or red to
indicate the current sensitivity level. Refer to the table for an explanation of the
transfer voltage sensitivity levels.
4. To select LOW sensitivity, press and hold the ON/OFF button until the LED flashes
green.
5. To select MEDIUM sensitivity, press and hold the ON/OFF button until the LED
flashes red.
6. To select HIGH sensitivity, press and hold the ON/OFF button until the LED flashes
amber.
7. To exit Program mode wait five seconds and all LED indicators will extinguish.
Program mode is no longer active.
Service
If the unit requires service, do not return it to the dealer. Follow these steps:
1. Review the Troubleshooting section of the manual to eliminate common problems.
2. If the problem persists, contact Schneider Electric IT (SEIT) Customer Support
through the APC by Schneider Electric Web site, www.apc.com.
a. Note the model number and serial number and the date of purchase. The model
and serial numbers are located on the rear panel of the unit and are available
through the LCD display on select models.
b. Call SEIT Customer Support and a technician will attempt to solve the
problem over the phone. If this is not possible, the technician will issue a
Returned Material Authorization Number (RMA#).
c. If the unit is under warranty, the repairs are free.
d. Service procedures and returns may vary internationally. Refer to the APC by
Schneider Electric Web site for country specific instructions.
3. Pack the unit in the original packaging whenever possible to avoid damage in
transit. Never use foam beads for packaging. Damage sustained in transit is not
covered under warranty.
4. Always DISCONNECT THE UPS BATTERIES before shipping. The United
States Department of Transportation (DOT), and the International Air
Transport Association (IATA) regulations require that UPS batteries be
disconnected before shipping. The internal batteries may remain in the UPS.
5. Write the RMA# provided by Customer Support on the outside of the package.
6. Return the unit by insured, pre-paid carrier to the address provided by Customer

Status LED Indicator Audible Indicator On Audible Indicator Terminates
Power On
The Back-UPS is supplying AC power to connected equipment. The green LED illuminates. None N/A
On Battery
Back-UPS supplying battery power to battery backup outlets.
The green LED illuminates. The LED
is not illuminated during the beeps.
Back-UPS beeps 4 times
every 30 seconds.
Beeping stops when AC power is restored or the
Back-UPS is turned off.
Low Battery warning
The Back-UPS is supplying battery power to the battery backup outlets
and the battery is near a total discharge state.
The green LED illuminates with rapid
green flashes.
The Back-UPS emits
rapid beeping, every
1/2 second.
Beeping stops when AC power is restored or the
Back-UPS is turned off.
Replace Battery
• The battery is disconnected.
• The battery needs to be charged, or replaced.
•Replace Battery LED flashes.
• Replace Battery and Power On
LEDs flash alternately.

Overload Shutdown
While on battery power an overload condition has occurred in one or
more of the battery backup outlets while the Back-UPS is operating on
battery power.
None Constant tone Back-UPS is turned off.
Sleep Mode
While on battery power the battery is completely discharged. The
Back-UPS will “awaken” once AC power is restored. None The Back-UPS beeps
once every four seconds.
The beeping stops when:
• AC power is restored
• If AC power is not restored within 32 seconds
• The Back-UPS is turned off
Building Wiring Fault
The building wiring presents a shock hazard that must be corrected by a
qualified electrical.
Building Wiring Fault LED
illuminates red None The Back-UPS is unplugged from the wall outlet
or is plugged into an improperly wired outlet.
Problem and Possible Cause Solution
The Back-UPS will not turn on
The Back-UPS has not been turned on. Press the POWER ON button.
The Back-UPS is not connected to AC
power, there is no AC power available
at the wall outlet, or the AC power is
experiencing a brownout or over
voltage condition.
Make sure the power cord is securely connected to
the wall outlet, and that there is AC power available
at the wall outlet.Where applicable, check that the
wall outlet is switched on.
The battery is not connected. Connect the battery. Refer to “Connect the Battery”
on page 1 of this manual.
In the event that the Back-UPS receives no AC
power and the battery is connected, a cold-start can
be initiated. Press and hold the Power On button
until the Back-UPS emits two beeps.
The Back-UPS is on, the Replace Battery LED flashes and the unit emits a constant
tone
The battery is disconnected. Refer to the “Connect the Battery” on page 1.
Connected equipment loses power
A Back-UPS overload condition has
occurred.
Remove all nonessential equipment connected to
the outlets. One at a time reconnect equipment to
the Back-UPS.
Charge the battery for 24 hours to make sure it is
fully charged. If the overload condition still occurs,
replace the battery.
The Back-UPS battery is completely
discharged.
Connect the Back-UPS to AC power and allow the
battery to recharge for eight hours.
PowerChute software has performed a
shutdown due to a power failure.
This is normal Back-UPS operation.
Connected equipment does not accept
the step-approximated sine waveform
from the Back-UPS.
The output waveform is intended for computers and
peripheral devices. It is not intended for use with
motor driven equipment.
The Back-UPS may require service. Contact SEIT Technical Support for more in depth
troubleshooting.
The Power On LED is illuminated and the Back-UPS beeps 4 times every 30 seconds
The Back-UPS is operating on battery
power.
The Back-UPS is operating normally on battery
power. At this point the user should save all open
files, and shutdown the computer. When AC power
is restored the battery will recharge.
The Power On LED flashes once every second while the Back-UPS beeps once every
second
The Back-UPS battery has
approximately two minutes of
remaining runtime.
The Back-UPS battery is near a total discharge state.
At this point the user should save all open files, and
shutdown the computer. When AC power is restored
the battery will recharge.
The Building Wiring Fault LED illuminates
The building wiring presents a shock
hazard that must be corrected by a
qualified electrical.
Do not operate the Back-UPS. Call a qualified
electrician to correct the building wiring fault.
The Back-UPS has an inadequate battery runtime
The battery is not fully charged.
The battery is near the end of useful
life and should be replaced.
Leave the Back-UPS connected to AC power for 24
hours while the battery charges to full capacity.
As a battery ages, the runtime capability decreases.
Contact APC by Schneider Electric at the Web site
www.apc.com, to order replacement batteries.
The connection from the Back-UPS to the internet is lost during a power outage
The modem has lost power. Connect the modem cable into one of the Battery
Backup + Surge Protection outlets.
