INSTALLATION | (continued) |
Controller Ground | Harnesses |
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.
Engine Starting Contacts
Customer connections for engine control contact and TS auxiliary contacts connections are located on terminal block TB which is mounted on the front lower left of the transfer switch. Refer to wiring diagram provided with the Series 300 ATS and connect the engine start wires to the appropriate terminals. See Figure
Table A. Engine start connections.
