Basic Operation (continued)

UPS Self-Test

• Initiate a UPS self-test by pressing the ON/OFF/TEST/MUTE button A for 2 seconds while the UPS is ON and operating from utility power.

(Note: If you hold the ON/OFF/TEST/MUTE button for only 1 second, the UPS will turn OFF, interrupting the flow of power to connected equipment.)

During the self-test operation, the UPS will switch to On Battery mode for 20 seconds. The alarm will emit a beep 4 times every 7 seconds.

Do not attempt to test the UPS by unplugging it from the wall outlet. This will remove the UPS system’s ground connection and places connected equipment at risk.

UPS Cold Start

To use the UPS system as a stand-alone power source when AC power is unavailable (i.e. during a blackout), press the ON/OFF/TEST/MUTE button A for 1 second (the UPS will beep when

1 second has elapsed) to turn the UPS system ON. The UPS will then provide power to its output receptacles until battery reserves have been depleted.

Do not attempt to cold-start the UPS system while it is disconnected from the wall outlet. The wall outlet provides grounding that helps to protect connected equipment.

Mute Alarm

• Mute the audible alarm by pressing the ON/OFF/TEST/MUTE button A for 2 seconds.

Note: Muting is disabled if a Low Battery or Overload condition is detected.
