System ground
The generator has a system ground that connects the generator frame components
to the ground terminals on the AC output receptacles. The generator neutral is
oating, which means that the AC stator winding is isolated from the grounding
fastener and the AC receptacle ground pins. Electrical devices, such as RCD,
requiring a grounded neutral may not operate properly from this generator.
NOTICE
Make sure the control panel, louver and the inverter bottom side cooling well and
without chips, mud and water come in. it may damage the engine, inverter or
alternator if the cooling vent blocked.
Do not mix the generator with other stuff If moving, storing or running the unit.
It may cause the generator damage or bring property safety issue when the
generator in leakage.

3.3 Overload indicator light (Red)
The overload indicator light comes on when an overload of a connected electrical
device is detected, the inverter control unit overheats, or the AC output voltage ri-
ses. Then, the AC protector will trip, stopping power generation in order to protect
the generator and any connected electric devices. The AC pilot light (Green) will go
off and the overload indicator light (Red) will stay on, but the engine will not stop
running.
When the overload indicator light comes on and power genera-
tion stops, proceed as follows:
1. Turn off any connected electric devices and stop the engine.
2. Reduce the total wattage of connected electric devices within
the rated output.
3. Check for blockages in the cooling air inlet and around the
control unit. If any blockages are found, remove.
4. After checking, restart the engine.
Tip: The overload indicator light may come on for a few seconds at rst when
using electric devices that require a large starting current, such as a compressor
or a submergible pump. However, this is not a malfunction.
