This unit is intended for indoor use only.
Do not operate this unit 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 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 Back-UPS power cable directly into a wall outlet. Do not use
surge protectors or extension cords.
* 2 IEC jumpers for BX1100CI.
Connect the Battery
Connect the battery connector prior to using the UPS.
Pull the battery connector handle down. Then push the connector into the UPS.
The battery charges fully during the first 10 hours while the Back-UPS is
operating on AC power.
Do not expect full battery runtime capability during the initial charge period.
There are no serviceable parts in the Back-UPS. Do not attempt to op en or
repair the Back-UPS as this will void the warranty. The battery in this unit is
not replaceable. Contact APC through the Web site www.apc.com, for
customer support.

These outlets provide battery backup power to connected equipment for a limited period of time
during power outages and voltage fluctuations.
The Battery Backup +Surge Protection outlets provide battery power to connected equipment only
when the Back-UPS is turned on.
Connect critical equipment such as a computer, computer monitor, modem or other data sensitive
devices to these outlets.
Do not connect aquarium equipment, laser printers, paper shredders, sump pumps, or fans to these
outlets as the modified sine wave output of the Back-UPS may cause these devices to experience a
decrease in performance.
Do not connect surge strips or surge protectors to these outlets.
AC power inlet Connect the Back-UPS to AC power.
Circuit breaker Use to reset the system after an overload condition has occurred causing the circuit breaker to trip.

Transfer Voltage and Sensitivity Settings
Automatic Voltage Regulation
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.
No-load Shutdown
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.
Voltage Sensitivity Adjustment
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 P
OWER 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
5. To select MEDIUM sensitivity, press the
6. To select HIGH sensitivity, press the
ON/OFF button until the On Line LED flashes green.

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no longer active.
