GROUNDING PIN
This product is for use on a nominal 120 V or nominal 220 V circuit, and has a grounding plug that looks like
the plug illustrated in sketch A in Figure 1. 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 a properly grounded out-
let 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. When-
ever the adapter is used, it must be held in place by the metal screw.
Note:
In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
