Single Phase Motors
The factory assembled fan head is equipped with a 12 foot long cord and connector. To turn on fan, plug it in; to turn off fan, unplug it.
Three Phase Motors
A cord and connector is not supplied with three phase motors. These fans will need to be fitted with an appropriate cord and connector or hard wired directly to a power source. It the fan is supplied with finger guards, the rear finger guard will need to be partially removed to access the motors internal wiring. Remove all but one of the self-tapping screws and place them in a safe place. You will use them again. Rotate the guards around on the single self-tapping screw. Wire the fan. Replace the guard using the saved self tapping screws. When looking at the front of the fan, the blade should be turning clockwise. It it does not, the electrical connection wires may need to be reversed. If reversing the wires does not work, contact your factory representative.
