The five LEDs illuminate with a steady glow to indicate battery capacity. Battery capacity is shown

for five seconds after the Status Change button is pressed. The LEDs show the battery capacity as a

range, ± 5% The LEDs’ battery level meanings and colors are:

LED 1

LED 2

LED 3

LED 4

LED 5

100-76% — Green

75-51% — Green

UPS Status Indicators

LEDs on the display panel illuminate with a steady glow or flash to indicate the UPS’s status:

Normal Mode—The Normal Mode indicator illuminates (LED 9) with a steady glow when utility

power is available and within the input specifications.

Battery Mode—The Battery Indicator illuminates (LED 10) with a steady glow when the UPS is

operating on battery

AVR Boost, AVR Buck—When the UPS is in AVR Boost/Buck Mode, the LED display will indicate

the relative load level on the output of the UPS and will flash LED 1 (boost) or LED 2 (buck) to indi-

cate which mode the UPS is in.

Weak Battery—When the UPS battery voltage is low, the LED display will indicate the relative load

level on the output of the UPS and LED 3 will flash as a warning.
