PSC MOTOR:  NOTE:  PSC motor option 

DOES NOT provide fan relay or low voltage 

fan circuit.   
 

Figure 5 illustrates the internal wiring for the 

unit.  
 

The utility box (4x4 junction box or “j-box 

only”) is mounted on the coil connection 

side of the unit. All leads pass through a 

strain relief where they enter the utility box.  
 

Wiring within the cabinet has been positively 

located and supported so that it does not 

pass over sharp metal edges or come in 

contact with moving parts. After servicing, 

properly position electrical leads in their 

original supports.
