APC BX1100U-LM Leaflet

•  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 three to five 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.

The battery in the Back-UPS BX800U-LM and BX1100U-LM is not user-replaceable. Contact Schneider 

Electric IT (SEIT) Technical Support for a list of authorized service centers near you.

Power On 

The Back-UPS is supplying AC power 

to connected equipment.

The On Line LED 

illuminates green.

The Back-UPS is supplying battery 

power to battery backup outlets.

The On Line LED 

illuminates green.
The LED is not 

illuminated during 

the beeps.

Back-UPS 

beeps 4 

times every 

30 seconds.

The beeping stops when 

AC power is restored or 

the Back-UPS is turned 

off.

The Back-UPS is supplying battery 

power to the battery backup outlets 

and the battery is near a total 

discharge state.

The On Line LED 

flashes green.

The Back-

UPS emits 

rapid 

beeping.

second)

The 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.

• The Battery LED 

flashes red.

• Battery and On Line 

LEDs flash 

alternately.

PowerChute Personal Edition Software allows you to use your computer to access additional power protection 

and management features of the Back-UPS.

Connect the Back-UPS to a computer using a USB cable. Plug one end into the USB Port on the rear panel of the 

Back-UPS and the other into a USB port on your computer.

Connect the battery by pulling the battery connector 

handle down, and then pushing it into the unit.

Connect the Back-UPS BX800/1100 U-LM power cable 

directly to a wall outlet. Do not use surge protectors or 

extension cords.

Press the ON/OFF button to turn on the unit.
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 AC power, whether the unit is turned ON or OFF.

Automatic Voltage Regulation boosts the AC voltage when it drops below safe levels. This allows the 

equipment that is connected to the Back-UPS to operate during low voltage conditions. Automatic Voltage 

Regulation will also regulate high voltage conditions down to a safe level.
The Back-UPS will switch to battery power if the AC input voltage level becomes too low or too high for the 

Automatic Voltage Regulation feature to compensate, or if the AC power is experiencing voltage fluctuations.

The UPS will shut down to conserve energy if while operating on battery power the UPS detects that connected 

equipment is using less than 15 W of energy for more than 15 minutes.
No-load shutdown can be enabled or disabled through Program mode described below.
If the Back-UPS switches to battery power too frequently or too infrequently, adjust the transfer voltage and 

sensitivity settings:

1 . Verify that the Back-UPS battery is connected. Connect the Back-UPS to a wall outlet. The 

Back-UPS should be turned off.

2 . Press and hold the POWER ON/OFF button for 10 seconds. The LEDs will illuminate green and red 

alternately, to indicate that the Back-UPS is in Program mode.

3 . The LEDs will flash either green, red or green and red alternately to indicate the current sensitivity level. 

The Back-UPS will beep to indicate that No-load Shutdown is enabled. Refer to the table for an explanation 

of the transfer voltage sensitivity levels.

4 . To select LOW sensitivity, press the ON/OFF button until the On Line LED flashes green.
5 . To select MEDIUM sensitivity, press the ON/OFF button until the Battery LED flashes red.
6 . To select HIGH sensitivity, press the ON/OFF button until the On Line and Battery LEDs flash green and 

red alternately.

7 . To exit Program mode wait for five seconds and both LEDs will extinguish. Program mode is no longer 

active.
