PRIMARY AND SECONDARY WIRING
CONNECTIONS
1.
As shown in Figure 63, connect a two-pair
twisted 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 15.
BI-PARTING GATE SYSTEMS
2.
Attach a ring terminal to the shield wire
and connect it to the Smart DC Controller’s
convenient ground screw. Refer to Figure 63.
NOTICE
Connect the ground shield wire to only one
operator, not both.

NOTICE
Use a 2-pair, twisted, shielded cable with one pair of wires used to connect A-A and B-B terminals
between the two boards. The other pair will connect the Common terminals. The shield should
then be grounded on one end to one of the operators.
