Control Wiring
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.
