Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
GROUNDING
This product must 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 an appropriate grounding plug. The plug must be plugged into an outlet
that is properly installed and grounded in accordance with all local codes and ordinances.
• Improper installation of the grounding plug is able to result in a risk of electric shock.
• When repair or replacement of the cord or plug is required, do not connect the grounding wire to
either flat blade terminal.
• The wire with insulation having an outer surface that is green with or without yellow stripes is the
grounding wire.
• Check with a qualified electrician or serviceman when the grounding instructio ns are not complete ly
understood, or when in doubt as to whether the product is properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a
qualified electrician.
• This product is for use on a nominal 230V circuit and has a grounding plug similar to the plug
illustrated in the figure below.
• Only connect the product to an outlet having the same configuration as the plug.
• Do not use an adapter with this product.
Extension Cords:
• Use only an extension cord that has a grounding plug and a receptacle that accepts the plug on the
product.
• Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG
2
(2.5 mm
• An undersized cord results in a drop in line voltage and loss of power and overheating.
