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.
