OVERLOAD WARNING
The overload indicator light comes on when electricity over
the rated output is required by the connected electrical
devices, or when the inverter control unit overheats, or the
AC output voltage rises. Then the AC protector will trip,
stopping power generation in order to protect the genera-
tor and any connected electric devices.
When the overload indicator light comes on and power
generation stops, proceed as follows:
1.
Turn off any connected electric devices.
