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 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.


  1. USB and Serial Data port: To use PowerChute Personal Edition, connect the supplied USB cable or an optional serial cable (not supplied).
  2. Telephone Cable Surge Protected ports: Connect the ground lead from an additional surge suppression device such as a stand-alone data line surge protector.
  3. AC Power Input: Use a power cable to connect the unit to AC power.
  4. Battery Backup outlets with Surge Protection: During a power outage or other AC problems, the Battery Backup outlets receive power for a limited time from the Back-UPS. Connect essential equipment such as desktop computer, computer monitor, modem or other data-sensitive devices into these outlets.
  5. Circuit Breaker: Use to reset the system after an overload condition has occurred causing the circuit breaker to trip.
  6. In/Out Ethernet surge-protected ports: Use an Ethernet cable to connect a cable modem to the IN port, and connect a computer to the OUT port.
  7. Surge Protected outlets: These outlets provide full-time protection from surges, even if the Back-UPS is off. Connect equipment such as printers and scanners that do not require battery backup protection.
