4.3 Wiring Diagram for GSV 400-450
The connection diagram below shows how the fan is connected to the power source (see Fig. 7).
Use a 3-conductor wire of min. 14 AWG with ground. Wiring must be run outside the duct, but can
run between the duct and the roof curb.
If variable speed is required, a variable frequency drive (VFD) can be used. This will eliminate the
need for a magnetic starter as shown. For installation and wiring, please refer to the instructions shipped
with the VFD.
