ELECTRICAL CONNECTIONS

WARNING:

 BE SURE POWER IS OFF AT THE ELECTRICAL PANEL BEFORE WIRING.

WARNING

High Voltage,
disconnect power
before servicing.

!

WARNING: ALL ELECTRICAL WORK SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN.

All motors are pre-wired at 240v in our factory. Rewire motor as per motor nameplate if running fan at 120v.  Please see the 
motor nameplate for wiring diagram.  Make electrical connections in motor connection box as per the motor nameplate. Follow 

chart #1

 for wire sizes. 

CHART# 1

FAN CONTROL:

The fans can be controlled with manual or automatic thermostatic controls.  These variable speed fans can be operated on low 
in milder weather to re-circulate warm air down from the ceiling, circulate fresh air, help remove moisture, remove dead air 
pockets and move unwanted gases to the exhaust.  In hot weather operate the fans on high to relieve heat stress and help 
control flies.  For best cooling effect, direct the air stream across the animals head and shoulders.

M0016 - 02/15/16                                                                                                                                                         Page 3 of 5

Note:

•  NEC Article 310-5 - * Minimum conductor size for general wiring at 115-440VAC is number 14AWG.
• Above wire sizes based on approximate 5% voltage drop during starting; copper conductors; and 75˚C type THHW, THW, THWN, RH, RHW insulation etc.  For aluminum wire, 

increase two wire size steps minimum.  See NEC Article 310 for ampacities af aluminum conductors.

• Type  S, SO,  SJ, SJO, etc flexible cable wire sizes.  See NEC Article 400 for ampacity.
