INDICATOR DESCRIPTION

Online

This LED is lit when the uninterruptible power supply is supplying utility power to the

connected equipment and performing double conversion to supply power to the con-

nected equipment. If not lit, the uninterruptible power supply is either not turned on, or

is supplying battery power. When flashing, the uninterruptible power supply is running

an internal self-test.

On Battery

This LED is lit when the uninterruptible power supply is supplying battery power to the

connected equipment.

Bypass

This LED is lit when the unit is sending utility power directly to the connected equip-

ment. Bypass mode operation is the result of an internal fault, an overload condition, or

a user-initiated command (performed manually through the manual bypass switch).

Battery operation is not available while the uninterruptible power supply is in bypass

mode. See Troubleshooting.

Fault

This LED is lit when the uninterruptible power supply detects an internal fault. See

Troubleshooting.

Overload

This LED is lit and the uninterruptible power supply emits a sustained alarm tone when

the connected loads are drawing more than the uninterruptible power supply power

rating. See Troubleshooting.

Replace Battery

Failure of a battery self-test causes the uninterruptible power supply to emit short beeps

for one minute and this LED to be lit. See Troubleshooting.

FEATURE FUNCTION

Power On

Press this button to turn on the uninterruptible power supply. (Additional capabilities

will be described later in the document.)

Power Off

Press this button to turn off the uninterruptible power supply.

Self-Test Automatic: The uninterruptible power supply performs a self-test automatically when

turned on, and every two weeks thereafter (by default). During the self-test, the uninter-

ruptible power supply briefly operates the connected equipment on battery.

If the uninterruptible power supply fails the self-test, the replace battery LED is lit and

immediately returns to online operation. The connected equipment is not affected by a

failed test. Allow the battery to recharge for 24 hours and perform another self-test. If it

fails, the battery must be replaced.

Manual: Press and hold the

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