Extension Cords; Key Features And Components - Delta 31-482 Operating Instructions And Parts Manual

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.

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
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.
