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. (Delta P/N 438-01-017-
0141 needed 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.
