NOTES:

1.Connect TRAN1 to H4 for 460 v units. Connect to H3 for 230 v. If 208/230 v units are run with a 208-v power supply, connect to H2.

2.Connect TRAN2 to black lead for 460 v units. Connect to orange lead for 230 v units. If 208/230 v units are run with a 208-v power supply, con- nect to red lead.

3.Circuit breaker must trip amps are equal to or less than 156% FLA for CB1 and CB2. All others are 140%.

4.If any of the original wire furnished must be replaced, it must be replaced with Type 90 C wire or its equivalent.

5.Compressors and/or fan motors are thermally protected.

6.Three phase motors are protected against pri- mary single phasing conditions.
