All wiring should be installed in accordance with National, State, and Local electrical
codes. Fans used to ventilate livestock buildings or other rooms where continuous
air movement is essential should be connected to individual electrical circuits, with a
minimum of two circuits per room. For electrical connection requirements, refer to diagram
on motor nameplate and to information enclosed with the Aerotech environmental control
to be used.
Single Phase Fans:
motor overload protection should be provided for each fan. A Circuit
Breaker Switch or slow blow motor type fuses must be used
See Figure 12.
See Aerotech
form
QM1400
for proper size.
NOTE:
A safety cut-off switch should be located adjacent to each fan.

Recommended wire Routing:
As the power cable exits the back of motor
form a drip loop and then run power cable
down along motor mount and "Zip" tie the cable
to motor mount to prevent cable from getting
tangled in the prop.
See Figure 11
. Then run
the cable out the drain hole to the circuit break-
er or control panel.
