On Battery

During on-battery operation, the on-battery LED illuminates and the UPS sounds an audible alarm

consisting of four beeps every 30 seconds. The alarm stops when the UPS returns to on-line

operation. Refer to On-Battery Operation, page 17, for details.

The 5-LED display on the right of the front panel shows the present charge of the UPS’s battery

as a percentage of the battery’s capacity. When all five LEDs are lit, the battery is fully charged.

The LEDs extinguish, from top to bottom, as the battery capacity diminishes. The battery

capacity threshold is shown in the figure to the left (it is not listed on the front panel display).

As a low battery warning, any LEDs illuminated (for the given capacity) will flash. The low

battery warning setting can be changed from the rear panel (see Low Battery Warning Level,

page 17) or through the PowerChute software.

Overload

When the UPS is overloaded (that is, when the connected equipment exceeds the maximum

specified in the “maximum load,” section in Appendix A: Specifications, page 25), the overload

LED comes on and the UPS emits a sustained tone. The alarm remains on until the overload is

removed. The UPS continues to supply power as long as it is on line and the breaker does not trip,

but it will not provide power from batteries in the event of a utility voltage interruption.

Disconnect nonessential equipment from the UPS to eliminate the overload. If a continuous

overload occurs while the UPS is on battery, the UPS will turn off its output in order to protect

itself from possible damage.

Self-Test

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

default). Refer to User Configuration Items, page 19 for details on changing the interval.

Automatic self-test eases maintenance requirements by eliminating the need for periodic manual

self-tests. During the self-test, the UPS briefly operates the connected equipment on-battery. If

the UPS passes the self-test, it returns to on-line operation.

If the UPS fails the self-test it immediately returns to on-line operation and lights the replace

battery LED. 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. See Replacing the

Battery, page 21, for details.

How to Manually Initiate a Self-Test

Press and hold the on

TEST

button (on the front panel) for a few seconds before the self-test will

begin.

Replace Battery

If the battery fails a self-test, the UPS emits short beeps for one minute and the replace battery

LED illuminates. (If the LED flashes, the battery is disconnected.) The UPS repeats the alarm

every five hours. Perform the self-test procedure after the battery has charged for 24 hours to

confirm the replace battery condition. The alarm will stop if the battery passes the self-test.
