Basic Operation

(continued)

UPS Self-Test

• Initiate a UPS self-test by pressing the ON/OFF/TEST/MUTE button

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

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

for 2 seconds.

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