Wiring information is provided in the

following steps. Figure 2-5 shows the

Marker Interface Enclosure with three

markers connected. Figure 2-20 shows a

system installation diagram. Figure 2-32

shows the recommended cable routing and

an internal wiring diagram for the Marker

Interface Enclosure.

Note: The Marker Interface Enclosure

should be located at the marker tier

level. A pictorial detailing the mounting

of the Marker Interface Enclosure is

included with the Marker Kit installation

instructions (Drawing PN 7790107 or

Wiring Procedure

1. Observing the procedures described

previously in “Flashhead Cable” and

“Securing the Cable”, install a 5’

service loop in the cable near the

marker interface enclosure.

2. Prepare the flashhead cable:

a. Remove 6 inches of the outer

jacket.

b. Remove the exposed aluminized

Mylar shield and any filler material

between conductors.

3. Loosen the dome nut of one of the ¾”

cable strain reliefs located in the

bottom of the enclosure. Route the

flashhead cable from the flashhead

through the strain relief and tighten the

dome nut.

4. Connect the three conductor flashhead

cable to the terminal strip TB1 using a

non-flared flat tip screwdriver:

a. Connect the red wire to one of the

two terminals on the top row

labeled DC+.

b. Connect the black wire to one of

the two the terminals on the top

row labeled DC-.

c. Connect the bare drain wire to one

of the two the terminals labeled

GND.

5. Loosen the dome nut of one of the ½”

cable strain reliefs located in the

bottom of the enclosure. Insert 12” of

marker cable through the cable strain

relief and tighten the dome nut.

6. Prepare the marker cable by removing

4 inches of the outer jacket and any

filler material between conductors.

7. Connect the marker cable to connector

J1 located on the marker interface

board:

a. Connect the red wire to the

terminal labeled DC+.

b. Connect the black wire to the

terminal labeled GND.

8. Route the cable to the marker light

following the instructions supplied

with the marker kit.

9. Repeat steps 4-8 for the remaining

markers to be installed.

10. Install the flashhead cable from the

marker interface enclosure to the FH

370d by repeating steps 1-3.

NOTE: A 5’ service loop should be

installed for each flashhead cable

section (SC 370d to Marker Interface &

Marker Interface to FH 370d) near the

marker interface enclosure.
