GROUNDING INSTRUCTIONS
This product must be grounded. In the event of malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock.
This product is equipped with a cord having an equipment grounding conductor and a grounding plug.
The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
DANGER
Improper connection of the equipment-grounding conductor can result in a risk of
electric shock.
1.
The conductor with insulation having an outer surface that is green with or without yellow stripes is the
equipment-grounding conductor.
2.
If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding
conductor to a live terminal.
3.
Check with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in doubt as to whether the product is properly grounded.
Do not modify the plug provided with the product if it will not fit the outlet, have a proper outlet installed by
a qualified electrician.
4.
This product is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug illustrated
in Fig. A. A temporary adaptor, which looks like the adaptor illustrated in Fig. C, may be used to connect this
plug to a 2-pole receptacle as shown in Fig 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 adaptor must be connected to a permanent
ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place
by the metal screw.
