LED indicator definition
1) Fault Indicator（red）：On indicates when a fault occurred; Off means no fault
2) Indicator（Green）：On means AC is normal, Off means AC is not present,
blinking means voltage is beyond normal range
3) Inverter Indicator（Green）：On : when load is powered by inverter, Off : when it
is not working, blinking: when overload
4) Bypass Indicator（Green）：On : when UPS is in bypass mode, Off: not in bypass
mode; blinking: when the input is beyond normal range
5) Battery Indicator（Green）：On: when UPS is in battery mode, Off : Not in battery
mode; Blinking: when battery voltage is low or battery is not connected
6) Output Indicator（Green）：On: when there is output, Off: no output.
