Alarm Off Switch
The switch cancels the audible LOW BATTERY WARNING alarm. The
alarm remains disabled until line power is restored and the batteries are
recharged.
Manual Start / (Hold to Test) Switch
The switch is used to start the UPS from battery power whenever AC line
power is not available (“LINE PRESENT” LED OFF). The switch can also be
used to test the UPS’ backup capabilities (“LINE PRESENT” LED ON) without
interruption to the load.
Output Load Display
The green “25%, 50%, 75%, and 100%” LED’s indicate the loading on the
UPS. Whenever the output load exceeds the rated output of the UPS, the red
“OVERLOAD” LED lights. Note: Each successive LED lights depending upon
the load. If the UPS has a 75% load (displayed), then the 25%, 50% and 75%
LEDs will light. DO NOT EXCEED THE OUTPUT RATING OF THE UPS.
