A complete information package is furnished with each transfer switch including a complete connection diagram and schematic which details all necessary control circuit field connections.

The engine start control wires connect to the engine start relay terminals located to the left

of the microprocessor. Figure 5 shows the location of these terminals.

The terminals are clearly identified by a label on the microcontroller backplate. In the case of manual trans- fer switches, or in other applications not requiring the microprocessor, clearly marked terminal blocks are provided in the upper left corner of the control panel for the engine start control wires.
