Figure 17. 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.
