Introduction

The APC Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags, and surges from reaching your equipment. The uninterruptible power supply (UPS) filters small utility line fluctuations and isolates your equipment from large disturbances by internally disconnecting from the utility line. The UPS provides continuous power from its internal battery until the utility line returns to safe levels or the battery is fully discharged.

Connect the UPS to the Network (if Applicable)

Serial Port

Telephone/ Network Surge Suppression Ports

Use only interface kits approved by APC.

Use only the supplied cable to connect to the Serial Port. A standard serial interface cable is incompatible with the UPS.

The UPS features optional telephone/network surge suppression. Connect a single line telephone or a 10 Base-T/100Base-Txnetwork cable into theRJ-45/RJ-11telephone/network surge protection IN jack on the back of the UPS. Use the telephone cable (not supplied) or network cabling (not supplied) to connect the OUT jack to a fax modem or network port.

Start the UPS

1.Plug the UPS into a two-pole,three-wire,grounded receptacle only. Avoid using extension cords.110/120 V models: The power cord is attached to the UPS; the input plug is a NEMA 5- 15P.230 V models: The power cord set is supplied in the UPS literature kit.

2.110/120 V models: Check thesite wiring fault LEDlocated on the rear panel. It will be illuminated if the UPS is plugged into an improperly wired utility power outlet (seeTroubleshooting).

3.Turn on all connected equipment. (This allows the UPS to be used as a master on/off switch.)

4.Press the button on the front panel to power the UPS.

Note: The battery charges fully during the first four hours of normal operation. Do not expect full battery run capability during this initial charge period. Refer to www.apc.com for battery runtime charts.

5.For optimal computer system protection, install PowerChute Business Edition management software to fully configure UPS shutdown and alarm settings.
