4. Wiring
Electrical Hook-Up
As previously mentioned, All wiring should be installed in accordance with National, State and Local
electrical codes. A certified electrician should complete this portion of the installation to ensure safety and
that the wiring is correct for the application.
1. First, remove the back cover of the motor exposing the wiring block. (See Figure 4A.)
Figure 4A
2. The motor is designed to use either a solid clamping conduit on the side of the motor or the supplied
wire with a three-prong plug attached. In either case, it is important to attach the ground wire to the
ground lug as depicted in
Figure 4A . For correct motor rotation (CCW), the Red wire should be
located on the L2 connection as depicted. If this is not the case, switch the Red and Black wires.
Refer to wiring diagram on the side of the motor for correct wiring for 115V and 230V supply.
3. Fans used to ventilate livestock buildings or other rooms where continuous air movement is essential
should be connected to individual electrical circuits with a minimum of two (2) circuits per room.
For connection requirements refer to diagram on the motor nameplate. For single phase fans, motor
overload protection should be provided for each fan. A safety cut-off switch should be located next
to each fan. A circuit breaker switch or slow blow motor type fuses must be used.
(See Figure 4B.)
3 Phase fans require three (3) pole contactors with overload protection.
