Wiring Installation

All wiring should be in accordance with local ordinances

and the National Electrical Code, NFPA 70. Ensure the
power supply (voltage, frequency, and current carrying
capacity of wires) is in accordance with the motor name-
plate. Refer to the

Wiring Diagram

, below.

Fan accessories will determine the wiring installation

procedure you should follow. If your unit has a disconnect
switch, follow the wiring diagram provided on the discon-
nect switch and the wiring diagram on the motor. Correctly
label the circuit on the main power box and always identify
a closed switch to promote safety (i.e. red tape over a
closed switch).

Lock off all power sources before unit is wired to

power source. Restrain the wire as necessary to pre-
vent it from being pulled into any rotating parts.

Fan Wiring

Drill a wire access hole through the cabinet side below

one of the access doors. Attach the appropriate size wire
and conduit to the motor and run the wires to the control
panel. Attach wires (18 gauge minimum) to the damper
actuator (Red, Black, #3) and the temperature sensor (Red,
2-Black), if equipped, and run the wires to the control
panel. Attach the fan wires to the control panel terminals
according the diagram below.

A terminal (1) is available for use with remote stop con-

trols. Closing a relay between terminals 1 and 5 will do the
same function as pushing the stop button on the front of the
panel.

Wire the roof disconnect switch, if equipped, and the fan

motor. The fan should rotate clockwise, when looking up
from the bottom, in supply mode. The rotation may be
changed by switching two of the three motor leads. When
rotation is correct, reinstall the access panels.
