GROUNDING INSTRUCTIONS
- This product should be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
-
DANGER
- Improper use of the grounding plug can result in a risk of electric shock.
- If the cord or plug is necessary to repair or needs to be replaced, do not connect the grounding wire to a flat blade terminal. The grounding wire can be identified by its insulated outer surface. It will either be colored green or will not contain yellow stripes.
- Check with a qualified electrician or serviceman if you do not understand grounding instructions or if you do not know whether the product is properly grounded.
-
This product is for use on a nominal 120V circuit. It has a grounding plug that looks like the plug illustrated in sketch A.
- A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adapter should be used only until the properly grounded outlet (sketch A) can be installed by a qualified electrician. The green colored rigid ear lug and the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover.
- Whenever the adapter is used, it must be held in place by the screw.
-
If it is necessary to use an extension cord, use only a three wire extension cord that has a three-blade grounding plug, and a three-slot receptacle that will accept the plug on the product. Replace or repair a damaged cord.
