NOTES:

1.Fan motors are inherently thermally protected.

2.Three-phase motors are protected under primary single phase conditions.

3.Use conductors suitable for at least 194 F (90 C) when replacing factory wiring.

4.Use copper conductors only.

5.Wiring for field power supply must be rated at 165 F (75 C) minimum.
