7. Perform Steps 3 through 6 for each Load Disc you wire to
this junction box.
8. Replace the junction box cover if not ready to begin
wiring the junction boxes together.
Wiring Junction Boxes Together and to Signal Processor
Notes:
1. The procedure below assumes the conduit fitting and
conduit for wiring the junction box to the other junction boxes
and to the signal processor has been installed.
2. Seal all conduit fittings against water entry. Install drain holes at
conduit’s lowest elevation(s) to allow condensation to drain.
3. Use Belden™ 4-conductor shielded interconnect cable or
equivalent to wire junction boxes together and to the signal
processor. For lengths up to 50 feet (15.2 m), use Belden 8723.
4. For 6-wire cable of distances up to 100 feet, use Belden 9773.
5. All spliced wiring routed between junction boxes and signal
processor must be soldered and encapsulated in waterproof
heatshrink.
1. Remove the junction box cover.
2. See Figure 3-8. Route the 4-conductor cable through the fitting
into the junction box farthest from the signal processor. Connect
wires from the cable to the TB1 terminal in the junction box:
red or brown wire to +EX , white wire to +SIG , and black
wire to -EX , and blue or yellow wire to -SIG .
3. Route the cable through conduit to the next junction box.
Estimatethe required length of cable to the terminal strip,
allowing a little extra for strain relief. Cut the excess cable.
Connect wires from the cable to the TB1 terminal in the
junction box:
red or brown wire to +EX , white wire to +SIG ,
and black wire to -EX , and blue or yellow wire to -SIG .
4. Route another cable through the fitting into this junction box, and
attach wires to the TB1 terminal:
red or brown wire to
+EX , white wire to +SIG , and black wire to -EX , and blue or
yellow wire to -SIG .
5. Repeat Steps 3 and 4 until all junction boxes on the
vessel are wired together.
