Figure 9
All the logic input to the controller must be connected at J1 mating
connector. With the provided P1 mating connector (shipped with pin 3 and
pin 8 shorted) make the connections with AWG 24, (0.24 mm2) or smaller
wire to the pins indicated in the figure to obtain the desired capability.
The following table describes the signals available on the connector.
