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.
First, remove the back cover of the motor exposing the wiring block. See Figure 11.1 below:
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 11.1. 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 the wiring diagram on the side of the motor for correct wiring for 115V and 230V supply.
Fans used to ventilate livestock buildings where continuous air movement is essential should be connected to individual electrical
circuits with a minimum of two 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 cutoff switch should be located next to each
fan. A circuit breaker switch or slow blow motor type fuse must be used. See Figure 11.2 below. Three phase fans require three
pole contactors with overload protection.
