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.

3. 240 VOLT SINGLE PHASE OPERATION
The motor supplied with your saw is a dual voltage,
120/240 volt motor. It is set at the factory at 120 volts. If
it is desired to operate your machine at 240 volts, single
phase, it is necessary to reconnect the motor leads in
the motor junction box by following instructions given on
the motor nameplate or inside the junction box.
MAKE SURE MOTOR IS
DISCONNECTED FROM POWER SOURCE BEFORE
RECONNECTING MOTOR LEADS.
It is also necessary to replace the 120 volt plug, supplied
with the motor, with a UL/CSA listed plug suitable for
240 volts and the rated current of your machine as
illustrated in Fig. C. Contact your local Authorized Delta
Service Center or qualified electrician for proper
procedures to install the plug. The machine must comply
with all local and national electrical codes after the 240
volt plug is installed.
The machine with a 240 volt plug should only be
connected to an outlet having the same configuration as
the plug illustrated in Fig. C. No adapter is available or
should be used with the 240 Volt plug.
IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF
YOU ARE NOT SURE HAVE A QUALIFIED ELECTRICIAN
CHECK THE RECEPTACLE.

4. Permanently connected machines:
If the machine is intended to be permanently connected, all
wiring must be done by a qualified electrician and conform
to the National Electric Code and all local codes and
ordinances.
* THREE PHASE OPERATION: Three phase machines
are not supplied with a power cord and must be
permanently connected to a building’s electrical
system. Extension cords can’t be used with a three
phase machine.
* LVC MAGNETIC MOTOR CONTROL: If you purch-
ased a machine that has a Low Voltage Magnetic Motor
Control System, refer to its instruction manual for
installation guidance.
