Connect the battery to the UPS before use.  To connect the battery:

 Pull the top of the battery connector lever out of the unit, until the lever is horizontal.
 Push the battery connector lever completely into the unit, until the end of the lever is flush with the rear panel.

Press ON/OFF to turn on the unit.

A single short beep, and the green “Power On” indicator confirms that the Back-UPS is on and ready to provide 
protection.

The Back-UPS should charge for at least 10 hours to ensure sufficient runtime. The unit is being charged 
whenever it is connected to utility power, whether the unit is turned ON or OFF.

The Back-UPS indicates its operating status using a combination of visual and audible indicators. 

On

Off

On-line - Back-UPS is supplying conditioned utility power 
to the connected equipment

On (Off during 4 
beeps)

4 beeps repeated 
every 30 seconds

On-Battery - Back-UPS is supplying battery power 

Flashing

Rapid Beeping 
(every 1/2 second) 

Low Battery Warning - The Back-UPS has 1.5 minutes of 
remaining battery power

Flashing

Constant tone

Bad Battery Detected  - Battery needs to be charged, or is 
at end of life. (See Battery Replacement.)

Off

Short beep every 
4 seconds

Low Battery Shutdown  - During On Battery operation the 
battery power was almost completely exhausted, and the 
Back-UPS is waiting for utility power to return to normal

Off

Constant Tone

On Battery Overload - Connected equipment requires 
more power than provided by the Back-UPS battery. 
Unplug devices one at a time to remove overload, if not 
corrected Contact APC Technical Support

On Constant 

Tone 

On Line Overload - The power drawn by the connected

Backup 

Flashing 

Chirp every 2 
seconds

Charger Warning -Back-UPS has experienced an internal 
problem, but continues to power the load. Contact APC 
Technical Support

Off

Constant Tone

Charger Fault - Back-UPS has an internal problem, and is 
no longer powering the load. Contact APC Technical 
Support 

Automatic Voltage Regulation boosts the utility voltage 
when it drops below safe levels.  This allows the 
equipment plugged into the unit to operate during low 
voltage conditions, conserving the battery power in the 
event of a power outage.

The Back-UPS will switch to battery power if the input  
voltage level becomes too low for the Automatic 
Voltage Regulation to compensate, or if the utility 
power is distorted.

If the Back-UPS switches to battery power too 
frequently or too infrequently, adjust the transfer 
voltage and sensitivity settings:

1. Ensure the Back-UPS is off. Plug it into utility 

power. 

2. Press and hold ON/OFF until the LED repeatedly 

flashes.  The unit is now in Program Mode. 

3. Release the button.  The LED will flash once, 

twice, or three times per second, indicating the 
current setting.  See Transfer Voltage and 
Sensitivity Settings. 

4. Press ON/OFF within two seconds to change the 

setting.  Each time the button is pressed, the LED 
will flash at a different rate: once, twice, or three 
times per second, indicating the new setting.  
Continue pressing the button until the desired 
setting is reached.  If the button is not pressed 
within five seconds, the Back-UPS will exit the 
Program Mode. 

5. To exit Program Mode, release the button and 

wait for the LED to stop flashing.

 Surge Protection

These outlets are powered whenever the Back-UPS is switched 
ON. During a power outage, or other utility problems (brownouts, 
over-voltages), these outlets will be powered for a limited time by 
the Back-UPS. Plug the computer and monitor into these two 
outlets.

Connect AC Power Cord

 

Plug the Back-UPS power cord into a wall outlet, not a surge 
protector or power strip. The outlet should be near the equipment 
and easily accessible. 

Once per second

Low

155 - 280

The Back-UPS will switch to battery power less often.  Use with equipment that is not 
sensitive to low or high level voltage levels or minor voltage waveform distortions.

Twice per second

Medium
(factory default)

160 -280

Default, use in normal conditions.

Three times per second
 

High

165 - 270

The Back-UPS will switch to battery power during any small fluctuation in voltage.  
Use with equipment that is sensitive to low or high level voltage levels or minor 
voltage waveform distortions.
