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.
Concerning the Power Cord
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 or branch circuits. Check the speciﬁcation page of
this owner's manual to be certain. Do not overload wall 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. Periodically 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 exits the appliance
