Remote CLD Panel Wiring
The Remote CLD requires a 24 VAC power source and a shielded, twisted-
pair wire between the panel and the Clear Language Display. See
Figure 30 .
As shown in Figure 31 , the wire runs from terminals J3A-1(+) and J3A-2(-) in
the unit's buffer module (1U7) to terminals J1(+) and J1(-) in the Remote CLD.
Be sure that one lead is connected to the (+) terminal at each end and the
other lead is connected to the (-) terminal at each end.
For units #2, #3 and #4 wire similarly as shown in Figure 31 .
Do not run the shielded, twisted-pair wire in a conduit that also contains
circuits of greater than 30 volts. Attach the shield to a grounding lug in the
unit's control panel. Cut and tape the shield at the Remote CLD panel, as
shown in
Figure 30 .
