Instructions for Connection To The Power Supply
And The Electrical Ground
The machine has a power cord with three conductors and
a plug with three terminals. For maximum protection
against electric shock, use a circuit that is protected by
a ground fault circuit interrupter.
This machine uses a 110 TO 120 volt AC 60 cycle
electrical circuit. Make sure you have the correct
voltage and frequency before connecting the
power cord to an outlet. The machine has a plug as
shown in Figure A. If a receptacle connected to the
electrical ground as shown in Figure A is not available,
use an adapter as shown in Figure C. This adapter must
be connected as shown in Figure B to an electrical
ground in the electrical outlet. Make sure you use the
plate screw and the tab to fasten the adapter.
WARNING: To prevent possible electric
shock, protect the machine
from rain. Keep the machine
in a dry building.
WARNING: For maximum protection
against electrical shock, use
a circuit that is protected by a
ground fault circuit inter-
rupter. Consult your electri-
cal contractor.

cords replaced by an autho-
rized service person.
EXTENSION CORDS
