5. Secure Safety Cable to Main Fan Unit
CAUTION: Do not remove the main fan unit from its protective packaging or place it on a flat surface prior
to hanging it.
CAUTION: To prevent damage, avoid contact with the stator wires located on the bottom of the main fan
unit.
CAUTION: The main fan unit is heavy. Use caution when raising it.
Raise the main fan unit directly from its packaging to the extension tube. Route the three sets of wires from the
main fan unit up into the bottom of the extension tube and out the rectangular access hole near the bottom of
the tube. Ensure the wires are positioned inside the grooves on the motor shaft. Note: Wiring not shown in the
illustrations below.
While supporting the main fan unit, secure the safety cable to the motor shaft using the Safety Cable Hardware
as shown. Insert the clevis pin through the safety cable lug and motor shaft, and then insert the straight leg of the
cotter pin into the small hole on the clevis pin.
