Load Level LEDs

The front panel displays the total load current or watts plugged into the UPS (see Figure 13).

66-100% 33-66% 5-33%

Figure 13. Load Level LEDs (Normal Mode)

Each LED represents 1/3 of a full load rating. When the UPS is approximately fully loaded (66-100%), all three LEDs illuminate. If the load is 33-66% of UPS capacity, the third and fourth LED illuminate. The last LED illuminates if the load is between 5% and 33%.

If any Load Level LEDs are red, see page 35 for more information.

Initiating the Self-Test

Press and hold the button for three seconds to initiate the self-test. During the test, individual LEDs illuminate as various parts of the UPS are checked. If the UPS finds a problem, an LED indicates where the problem is. For more information, see “Troubleshooting” on page 33.

NOTE All three Battery Charge LEDs should be lit and the UPS must not be in

Battery mode to perform the self-test.
