separate grounding is not required. Note that AC power
outlet configurations may differ from country to country.
Caution
Caution
•
To prevent a possible explosion, do not connect ground to a gas pipe.
•
Do not connect ground to telephone wires or lighting rods. This may be dangerous during electrical storms.
•
Connecting ground to plastic has no effect.
•
Ground wires should be connected when an extension cord is used.
CAUTION 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.
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
