3. 240 VOLT SINGLE PHASE OPERATION
The motor supplied with your machine is a dual voltage,
120/240 volt motor. It is shipped ready-to-run for 120
volt operation. However, it can be converted for 240 volt
operation.
A qualified electrician should do the conversion, or the
machine can be taken to an Authorized DELTA
Center. When completed, the machine must conform
to the National Electric Code and all local codes and
ordinances.
The machine is converted by re-wiring the motor for 240
volts, installing a 240 volt plug on the power supply cord
and replacing the switch with one that is rated for 240
volt operation.
Be sure the 240 volt plug is only used in an outlet having
the same configuration as the plug illustrated in Fig. C.
No adapter should be used with the 240 volt plug.
In all cases, make certain that the receptacle
in question is properly grounded. If you are not sure, have a
qualified electrician check the receptacle.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension
cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine's plug. When using
an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a
drop in line voltage, resulting in loss of power and overheating. Fig. D-1 or D-2, shows the correct gauge to use depending
on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
