CAUTIONS & WARNINGS
Grounding InstructionsThis product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for
electric shock. This product is equipped with an equipment-grounding conductor and a grounded 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. Check with a qualified electrician or serviceman if you are 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. This product is for use only on a nominal 120V circuit and has a grounded plug that looks like the plug illustrated in Figure A
below. Make sure that the product is connected to an outlet having the same configuration as the plug. An adapter should
never be used with this product, such as shown in Figure B below.
