The fuse disconnect switch is an optional
component offered by MacroAir. Reference page 5
for fuse size based upon the incoming power and
fan diameter.
4.1.1: Mount the fuse disconnect switch outside of
the swept area of the fan airfoils.
4.1.2: Wire the power cable from the fan to the
bottom of the fuse block. Then wire the incoming
power source to the disconnect switch.
4.1.3: In the diagram below, a three phase system
is shown. For a single phase system, phase 1
would be connected to L1, neutral would be
connected to L2, and L3 would be left not
terminated.
