Controller Ground
A grounding wire must be connected to the controller’s
lower left mounting stud. Because the controller is
mounted on the enclosure door, a conductive strap
must be used between the enclosure and the door.
This connection provides proper grounding which does
not rely upon the door hi nges.
Harnesses
The transfer switch is connected to the left side of the
controller by a plug–in harness (two plugs).
Auxiliary Circuits
Connect auxiliary circuit wires to appropriate terminals
on transfer switch as shown on the wiring diagram
provided with this Series 300 Automatic Transfer
Switch. Make the necessary auxiliary connections by
referring to Section 5, Control Features.
