Electrical Wiring 3.

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 Munters environmental control to be used. After wiring

check for proper motor rotation.

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 6A. See form QM1400 for proper size.

Three Phase Fans: motor overload protection should be provided for each fan. A three-pole motor starter or slow

blow motor fuses must be used. See Figure 6B.

If a frequency drive (inverter) is used, confirm that motors are rated for inverter duty at the voltage used. Shielded

power cable between frequency drive and each motor is highly recommended. Installation of line reactors is

recommended to reduce voltage spikes and harmonic distortion. Supplemental motor overload protection is also

recommended.

NOTE: A safety cut-off switch should be located adjacent to each fan.

Electrical WiringChapter 3

Three Phase Fans:

1) The use of a quality frequency drive and the installation of line reactors is recommended to

reduce voltage spikes and harmonic distortion.

2) Minimum operating frequency of 30 Hz.

3) Will require three pole contractors with overload protection (by others).

As the power cable exits the back of motor form a drip loop and then run power cable down along leg

of motor mount and "Zip" tie the cable to leg to prevent cable from getting tangled.

See Figure 7.

Then

run the cable out the drain hole to the circuit breaker or control panel. (Continued on next page).
