NOTES:

 

1.

If any of the original wire furnished must be replaced, it must

 

be replaced with type 90 C wire or its equivalent.

 

2.

Three phase motors are protected under primary

single

phasing conditions.

3. Use copper conductors only.

4. TRAN is wired for 230 v unit. If unit is to be run with 208 v power supply, disconnect BLK wire from 230 v tap (ORN) and connect to 208 v tap (RED). Insulate end of 230 v tap.
