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.
6. Phase rotation sequence is L2-L1-L3.
7. TRAN1 and TRAN2 power separate 24-V circuits.
These circuits should not be interconnected and
separation must be maintained.
8. Transformers are factory wired for 240 v operation.
Move the black wire to the 208 v tap for 208 v
operation.
