5.1 Control Board Connections
Analog and Digital input and output connections are made at the Control Wiring Terminals shown in
Figure 5-1.
Control wire connections can be made using shielded twisted pair #18 AWG (0.8mm2) wire minimum.
The cable must also have an overall shield and not exceed 100 feet (30m) in length. Control wire
cables must be separated from power wiring. Separate parallel runs of control cables and power
cables by at least 3". Cross power wires at right angles only. Insulate or tape ungrounded end of
shields to prevent contact with other conductors or ground.
The Control Wiring Terminals are prewired to allow front panel Potentiometer and FWD-Off-Rev switch
operation. Simply remove these terminal connections (pins 1 to 7) and connect external devices as
desired. These terminals are described in Table 5-1.
