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 ON/OFF button for 10 seconds. The 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Program mode is no longer active.

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 APC Customer Support through the APC 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 APC 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 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 

Support.

Select models are ENERGY STAR

 qualified.

Power On 
The Back-UPS is supplying utility 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 
flashes once at the end of every 2 seconds.

Back-UPS beeps for 2 
seconds when entering 
battery mode.

Beeping stops at the end of the first two seconds. A 
constant beep at the initial two seconds indicates the 
Back-UPS has entered the battery mode.

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 utility power is restored or the 
Back-UPS is turned off.

• 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 utility power is restored.

The Back-UPS beeps once 
every four seconds.

The beeping stops when: 

• Utility power is restored
• If utility 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.

The Back-UPS has not been turned 
on.

Press the P

OWER

 

ON

 button.

The Back-UPS is not connected to 
utility power, there is no utility power 
available at the wall outlet, or the 
utility 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 utility 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 utility 
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 battery is disconnected.

Refer to the “Connect the Battery” on page 1.

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.

The Back-UPS battery is completely 
discharged.

Connect the Back-UPS to utility power and allow 
the battery to recharge for eight hours.

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 APC Technical Support for more in depth 
troubleshooting.

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 utility 
power is restored the battery will recharge.

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 utility 
power is restored the battery will recharge.

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 battery is not fully charged.

The battery is near the end of useful 
life and should be replaced.

Leave the Back-UPS connected to utility power for 
16 hours while the battery charges to full capacity.
As a battery ages, the runtime capability decreases. 
Contact APC at the Web site www.apc.com, to 
order replacement batteries.

The modem has lost power.

Connect the broadband modem into one of the 
Battery Backup + Surge Protection outlets.
