Earth wire should be connected.
If the earth wire is not connected, there is possible a danger of electric shock caused by the current leakage.
Grounding Method with Ground insert space Terminal
If the AC current outlet has a ground terminal, then separate
grounding is not required. Note that AC power outlet configuration
may differ from country to country.
Ground Terminal
Outlet with ground terminal
Most appliances recommend they be placed upon a dedicated circuit; that is, a single outlet circuit
which powers only that appliance and has no additional outlets. Overloaded wall outlets, loose or
damaged wall outlets, extension cords, frayed power cords, or damaged or cracked wire insulation are
dangerous. Any of these conditions could result in electric shock or fire. Practically examine the cord of
your appliance, and if its appearance indicates damage or deterioration, unplug it, discontinue use of
the appliance, and have the cord replaced with an exact replacement part by an authorized servicer.
Protect the power cord from physical or mechanical abuse, such as being twisted, kinked, pinched,
closed in a door, or walked upon. Pay particular attention to plugs, wall outlets and the point where the
cord exists the appliance.

Breaker
Connect the ground Wire to the socket provided exclusively
for Grounding.
If grounding methods described above are not possible, a
separate circuit breaker should be employed and installed by
a qualified electrician.
Caution
• To prevent a possible explosion, do not connect ground to a gas pipe.
• Do not connect to telephone wires or lightning rods, This may be dangerous during electrical storms.
• Connecting ground to plastic has no effect.
