Delta 34-814 Five Horsepower Motors, Three Phase Operation, Magnetic Push Button Controls, Fig. D

FIVE HORSEPOWER MOTORS

The motors supplied with single phase, 5 horsepower Unisaws are designed to be operated from a 220-240 volt power system.

The 5 horsepower Unisaws are not supplied with a power cord. They must be permanently connected to the building electrical system and grounded according to the National Electrical Code. Since they are permanently connected to the building electrical system, extension cords cannot be used with the 5 horsepower Unisaw.

THREE PHASE OPERATION

Three phase Unisaws are not supplied with a power cord. They must be permanently connected to the building electrical system and grounded according to the National Electrical Code. Since they must be permanently connected to the building electrical system, extension cords cannot be used with three phase Unisaws.

MAGNETIC PUSH BUTTON CONTROLS

If you purchased the Unisaw with a magnetic starter, transformer and overload protection (LVC), refer to the separate electrical instruction manual supplied with the machine.

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, 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.
