APC BN4001 Owner's Manual

The Back-UPS is shipped with one battery cable disconnected. Remove the “Stop! 
Connect the Battery” label that covers the outlets. Prior to connecting any equipment 
to the unit, connect the battery cable to the unused battery terminal. It is normal for 
small sparks to be seen when the battery cable is connected to the battery terminal.    

•

Horizontal installation, use 2 screws 7.3" (186.3 mm) apart. 

•

Vertical installation, use 2 screws 5.4" (137.2 mm) apart. 

•

Allow 5/16” (8 mm), of the screw to protrude from the wall.

Use only approved APC replacement battery cartridges.

Deliver used batteries to a battery replacement facility in the packaging provided by 
APC with the replacement battery cartridge. To order replacement battery cartridges 
contact APC.

Battery backup outlets provide protection to connected equipment when the 
Back-UPS is turned on and connected to utility power.

Battery backup outlets receive power from the Back-UPS for a limited period of time 
when a power outage, or brownout condition occurs.

Battery backup outlets provide protection from power surges or spikes.

Connect a broadband modem and wireless router to the outlets. Voice over IP (VOIP) 
phones (if applicable) should also be plugged into battery backup outlets.

To maximize runtime in the event of a power outage only connect networking 
equipment to battery backup outlets.

Surge protection outlets provide protection to connected equipment when the 
Back-UPS is connected to utility power, and is switched on or off.

Surge protection outlets provide protection from power surges or spikes.

Connect non-networking peripheral devices such as printers and scanners that do not 
need to remain on during power outages, or utility problems to the surge protection 
outlets.

The Back-UPS protects equipment from power surges when connected by ethernet 
through the Back-UPS RJ-45 connectors.

Note: The Service port is intended for use during manufacturing. Do 
not connect anything to this port. Do not alter the functionality of 
the Back-UPS as this will void the warranty.

Press the P

OWER

 ON button located on the top of the Back-UPS. The Power On/

Replace Battery LED will illuminate and a single short beep will be audible to 
indicate that the Back-UPS is providing protection for connected equipment.

The Back-UPS battery charges fully during the first 16 hours while connected to 
utility power. The Back-UPS battery will charge while the Back-UPS is switched on 
or off and is connected to utility power. Do not expect full battery run capability 
during the initial charge time. 

If the red Building Wiring Fault LED located on the side of the Back-UPS 
illuminates, do not operate the Back-UPS. Have a qualified electrician correct the 
building wiring fault.

The standard warranty is 3 years in the USA and Canada, 2 years in all other regions
