you are using Mac OSX, use the native shutdown feature to help protect your
system. See the documentation provided with your computer.
Installation
Use the USB communication cable supplied with the Back-UPS to connect
the data port on the Back-UPS to the USB port on your computer. On the
computer, go to www.apc.com Search for “PowerChute Personal Edition”
then click on “View Details” to download the latest version of PCPE
software. Click the download link and select Software product. Select the
appropriate operating system. Follow directions to download the software.
Connect the Equipment
Battery Backup and Surge Protected outlets
When the Back-UPS is receiving input power, the Battery Backup with
Surge Protection outlets will supply power to connected equipment. During
a power outage or other detected AC problems, the Battery Backup outlets
receive power for a limited time from the Back-UPS.
Connect equipment such as printers, fax machines, scanners, or other
peripherals that do not need battery backup power to the Surge Protection
Only outlets. These outlets provide full-time protection from surges even if
the Back-UPS is switched OFF.

due to a power outage and has not
fully recharged.
Charge the battery cartridge for
16 hours.
The battery has reached the end of its
useful life.
Replace the battery.
The REPLACE
BATTERY indicator is
illuminated.
The battery has reached the end of its
useful life.
Replace the battery as early as possible.
The OVERLOAD
indicator is

indicator is
illuminated, all the
front panel
indicators are
flashing.
