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 Service

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.
