grounding conductor and grounding plug. The plug must always be inserted directly into an
electrical outlet that is properly installed and grounded in accordance with all local codes and

DO NOT USE AN EXTENSION CORD.
WARNING:
Improper connection of the equipment grounding conductor can
result in a risk of electric shock. Check with a qualified electrician
or service person if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug provided with the
power unit – if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
The unit has a grounding attachment plug. Make sure that the
power unit is connected to an outlet having the same configuration
as the plug. No adapter should be used with this power unit. The
power unit should be connected to an independent circuit breaker.
