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 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. Permanently connected machines:
If the machine is intended to be permanently connected, all wiring mentioned below 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 purchased a machine that has a Low Voltage Magnetic Motor Control
System, refer to its instruction manual for installation guidance. Some machines with LVC controllers must be permanently
connected to the building’s electrical system. Some are fitted with power cords and can be plugged into the appropriate
outlets.
