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 hinges.
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. Note the control features that are
furnished on this switch. Make the necessary auxiliary
connections by referring to Section 5, Control Features.
