Extension Cords - Delta 31-735 Manuel D'utilisation

3. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating between 150
- 250 volts, inclusive:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. C, the
machine will have a grounding plug that looks like the plug illustrated in Fig. C. Make sure the machine is connected
to an outlet having the same configuration as the plug. No adapter is available or should be used with this machine.
If the machine must be re-connected for use on a different type of electric circuit, the re-connection should be made
by qualified service personnel; and after re-connection, the machine should comply with the National Electric Code
and all local codes and ordinances.
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.

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-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.
