THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM

ELECTRIC SHOCK.

machine will have a grounding plug that looks like the

plug illustrated in Fig. A. Make sure the machine is

connected to an outlet having the same configuration as

the plug. No adapter is available or should be used with

this machine. If the machine must be re-connected for

use on a different type of electric circuit, the re-

connection should be made by qualified service

personnel; and after re-connection, the machine should

comply with all local codes and ordinances.

NOTE: In Canada, the use of a temporary adapter is

not permitted by the Canadian Electric Code.

IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE IN QUESTION IS

PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE

A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

A separate electrical circuit should be used for your machines:

FOR SINGLE PHASE UNITS (EXCEPT THE FIVE HORSEPOWER): This circuit should not be less than #12 wire

and should be protected with a 20 Amp time lag fuse.

FOR FIVE HORSEPOWER, SINGLE PHASE UNITS: The circuit should not be less than #10 wire and should be protected

with a 40 Amp time lag fuse.

FOR PERMANENTLY CONNECTED MACHINES: See No. 3 in “GROUNDING INSTRUCTIONS.”

If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching

receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the

switch is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the

machine. All line connections should make good contact. Running on low voltage will damage the machine. (See

“THREE PHASE OPERATION” and “LVC MAGNETIC MOTOR CONTROL” sections for more information on power

connections.)

DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

1. All grounded, cord-connected machines:

In the event of a malfunction or breakdown, grounding

provides a path of least resistance for electric current to

reduce the risk of electric shock. This machine is equipped

with an electric cord having an equipment-grounding

conductor and a grounding plug. The plug must be plugged

into a matching outlet that is properly installed and grounded

in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet,

have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding

conductor can result in risk of electric shock. The conductor

with insulation having an outer surface that is green with or

without yellow stripes is the equipment-grounding

conductor. If repair or replacement of the electric cord or

plug is necessary, do not connect the equipment-grounding

conductor to a live terminal.

Check with a qualified electrician or service personnel if the

grounding instructions are not completely understood, or if

in doubt as to whether the machine is properly grounded.

Use only 3-wire extension cords that have 3-prong

grounding type plugs and matching 3-conductor

receptacles that accept the machine’s plug. Repair or

replace damaged or worn cord immediately.
