Extension Cords - Delta 36-649 Instruction Manual

3. 240 VOLT SINGLE PHASE OPERATION:
The motor supplied with your saw is a dual voltage,
120/240 volt motor. If it is desired to operate your saw at
240 volts, single phase, it is necessary to reconnect the
motor leads in the motor junction box by following the
in-structions given on the motor nameplate.
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 the saw as illustrated
in Fig. C. Contact your local Authorized Delta Service
Center or qualified electrician for proper procedures to
install the plug. The saw must comply with all local and
national electrical codes after the 240 volt plug is
installed.
The saw 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

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.
