Electrical Installation (cont.)
Mounting the variable frequency drive (VFD)
WARNING: Ensure power is disconnected before installing the VFD!
WARNING: To avoid damaging VFD and fan controller, test the VFD and fan controller with a test cable!
CAUTION: To avoid a short circuit, be very careful not to get metal chips in the control!
The VFD enclosure does not provide conduit knockouts. Big Ass Fans recommends using a hole punch to create conduit knockouts in
the most accessible locations on the enclosure.
1. Select a mounting location
Select a mounting location that is shaded from direct sunlight and allows enough clearance for the door to fully open. The mounting
location should be a flat surface that is readily accessible, free from vibration, and an adequate distance from foreign objects or moving
equipment.
2. Predrill the VFD enclosure
Drill appropriately sized holes in the VFD enclosure to accommodate the conduit connectors.
Position the holes where the conduit can most accessibly exit the enclosure. Note: Use
appropriately rated connectors (IP56) to protect against foreign matter from entering the
enclosure.
3. Mount the VFD enclosure (to the wall)
Mount the VFD enclosure to the wall using the screws provided with the enclosure.
4. Wire the fan
Refer to the wiring diagrams on the following pages for your fan controller, and refer to page 34 for the motor wiring. Note:
Wiring is not shown in the illustration below.
