INDICATOR LIGHTS
• Monthly routine inspection: check if the LED indicator is fixed firmly.

have corrosion and that all the accessories of the indicator lights are completed, fixed firmly and have
not burned out. Also check if the incoming insulation is in compliance with the regulations.

ELECTRICAL GROUND SYSTEM
Electrical grounding is very important in electrical safety. The safety of human and equipment depends
largely on the integrity and safety of grounding equipment. If the grounding equipment is not solid, reliable
and does not comply with local standards, it will create risks for human lives and the equipment itself.
Therefore, careful inspection and timely maintenance must be carried out to keep the ground system in a
good condition.
• Weekly routine inspection: check if the grounding of the equipment is loose, lost or altered.
Observe carefully whether the grounding of the equipment is intact and if the anti-loosening device is
completed, damaged or removed.
• Monthly routine inspection: make sure whether the connection of electrical grounding system is rusty,
with oxidation or unstable; if it does, it will increase earth resistance. Also check if the grounding mark
is completed or damaged. Check the device in the switch box for looseness, corrosion, and rust.
• Annual routine inspection: make sure the grounding wires and terminals are in good condition. Use
the multi-meter to detect whether the grounding resistance meets or exceeds the standard grounding
requirements.
