: The light is on when the UPS is in fault condition. In the meantime, the alarm
beeps continuously.

: The light is a bar graph and indicates how much load is on the UPS.
The lights are in 25% increments. If the UPS is overloaded, the LED's show over 100%, then
you have connected too many devices into the UPS. Unplug the least critical equipment,
such as a printer etc.
