Fig. 25 —  Typical Line Voltage Wiring Schematic (50XCA012-24, 208/230-3-60 Units Shown)

a50-8504

*Disconnect can be factory or field-installed.

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.
