- the plug has pin/terminal(s) for grounding, and
- provided with three-conductor cable having enough cur-
rent capacity, and
- the cord set meetsregulatory requirementsfor the area.
Use of inadequate cord set leadsto fire or electric shock.

outlet, the total load must not exceed the rating of the wall
outlet.
If excessive current flowsin the wall outlet, fire may
result.
•Make sure the power cord isplugged in the wall outlet
securely.
Contact problemsmay lead to increased resistance,
overheating, and the risk of fire.
• Check whether the product isgrounded properly.
If current leakage occursin an ungrounded product, you
may suffer electric shock while operating the product.
