THREE PHASE OPERATION

Three phase MACHINES 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 MACHINES.

200-220 VOLT, THREE PHASE OPERATION

If the motor on your machine is wired for 200-220 Volt, Three Phase operation, proceed as follows when con- necting your planer to an electrical power system:

1.Remove the two screws that attach the switch cover (A) Fig. B, to the switch box and remove the switch cover (A).

2.Remove lower right knockout from bottom of switch box (B) Fig. C, and assemble a strain relief (not supplied) in its place.

3.Bring the three phase power line up through the strain relief, and connect the three power lines to terminals L1, L2 and L3, shown at (C) Fig. C, and connect the green ground wire to ground screw (D).

4.IMPORTANT: IF AFTER THE MACHINE IS IN OPERATION THE CUTTERHEAD REVOLVES IN THE WRONG ROTATION, INTERCHANGE ANY TWO OF THE THREE POWER LINES THAT ARE CONNECTED TO TERMINALS (C) FIG. C.

5.Replace switch cover that was removed in STEP 1.

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.
