7.3.2.3 Application Installation, 7A366-f
See Figure 7-8, for Tuned Receiver Coupler, Hi Z, 7A366-f application installation drawings. The
coupler terminals are connected as follows:
Terminals A & B connect to the wire leads that are connected to the shelter surge equipment
terminals which are in turn connected to the appropriate gauge twisted pair track leads that
connect to the rails.
Terminals C & D connect to the wire leads connected to “RX –“ and “RX +” on the GCE Lower
10-pin Connector
There must be a minimum of 500 ft. (152.4 m) separating the track connections of the Tuned
Receiver Coupler, Hi Z, 7A366-f from the track connections of the GCE Transmitter, 7A471.
Track wires connecting the Tuned Receiver Coupler, Hi Z, 7A366-f to the rails may be #9 AWG
for distances between the coupler and the track of up to 100 ft. (30.5 m). When the distances
are between 100 – 300 ft. (30.5 – 91.4 m) in length, track wires should be #6 AWG.
For distances greater than 300 ft. (30.52 m) but less than 2000 ft. (609.6 m), the Tuned
Receiver Coupler, Hi Z, 7A366-f should be replaced by the Line to Receiver Coupler, 7A388.
The 7A388 should be used in conjunction with either the Receiver Line to Rail Coupler, 7A377-
1-f, or the Receiver Line to Rail Coupler, 7A377-2-f (see paragraphs 7.3.4.1 and 7.3.4.4,
respectively).
