1. As shown in Figure 5-2, connect a shielded communications cable to the DUAL GATE inputs in each
unit. The inputs are located near the base of the Smart DC Controller. Be sure to connect the wires in pairs
to the same terminal ports (A-A, B-B, and COM to COM) on both units. See Table 5-1.
2. Attach a ring terminal to the shield wire and connect it to the Smart DC Controller’s convenient ground
screw. Refer to Figure 5-2.
Connect the ground shield wire to only one operator, not both.
