Section Ill Installation
Grounding Instructions
— WARNING —
Risk of electric shock could occur as a result of improper
grounding plug installation.
To reduce the risk of electric shock, this product must be grounded. In
the event of an electrical short circuit, grounding provides an escape wire
for the electric current.
This product is equipped with a cord having a grounding wire with an
appropriate grounding plug. The wire with insulation having a green or green
with yellow stripes outer surface is the grounding wire.
1. The plug must be plugged into a properly installed and grounded
outlet, which is in accordance with all local codes and ordinances.
2. If the plug provided does not fit the outlet, do not modify it in
any way. Have a qualified electrician install the proper outlet.
3. If repair or replacement of the cord or plug is necessary, do not
connect the grounding wire to either flat blade terminal.
4. Check with a qualified electrician or serviceman if the grounding
instructions are not completely understood, or if there is any
doubt whether the product is properly grounded.
For Grounded, Cord-Connected Products:
• Rated less than 15 amps and intended for use on a nominal
120V supply circuit:
a. This product has a grounding plug like the one depicted in
the illustration on the left.
b. Make sure the product is connected to an outlet having the
same configuration as the plug and no adapter should be
used.
• Intended for use on a circuit having a nominal rating of
more than 120V:
a. This product is factory-equipped with a specific electric cord
and plug, which allows connection to a proper electric circuit.
b. If reconnecting on a different type of electric circuit, re-
connection should be made by qualified service personnel.
c. Make sure the product is connected to an outlet having the
same configuration as the plug and no adapter should be
used.
