Typical Wiring Diagrams
Wiring diagrams are shown for motor packs and dampers installed with power ventilator fan equipment with single
speed motor. The damper will open when the fan is on and close when the fan is off. For connection to two-speed
fan motors or for other control sequences consult the factory. The wiring diagrams shown with end switches are for
applications where it is desirable to have the damper fully open before fan start-up.
