Automatic Self- Test

Manual Self-Test

The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by default).

During the self-test, the UPS briefly operates the connected equipment on bat- tery.

If the UPS fails the self-test, the replace battery LED illuminates and im- mediately returns to online operation. The connected equipment is not affected by a failed test. Recharge the battery for 24 hours and perform another self-test. If it fails, the battery must be replaced.

Press and hold the button for a few seconds to initiate the self-test.

CIRCUIT BREAKERS (208V MODELS ONLY)

Input Circuit Breaker One 40 Amp input circuit breaker is provided to the right of the rear connector plug and to the left of the battery pack connector.

Output Circuit Breakers Two output circuit breakers are provided.

On Battery Operation

The Smart-UPS switches to battery operation automatically if the utility power fails. While running on battery, an alarm beeps four times every 30 seconds.

Press the button to silence the UPS alarm (for the current alarm only). If the utility power does not return, the UPS continues to supply power to the connected equipment until the battery is ex- hausted.

If PowerChute is not being used you must manually save your files and power down before the UPS turns off.

DETERMINING ON BATTERY RUN TIME

UPS battery life differs based on usage and environment. It is recommended that the battery/batteries be changed once every three years. See the APC web site, www.apc.com, for on battery run times.
