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 outlet 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 metal screw.
Note: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
