• Use Belden 4-conductor shielded interconnect cable or equivalent to wire Junction Boxes together and to
the controller. For lengths up to 50 ft ( 15.2 m), use Belden 8723 cable.
• When wiring cable to Junction Box terminals, strip back 3 inches (76 mm) of cable sheathing to expose the
4-conductor wires and shield wire inside. Strip 1/4 inch (6 mm) of insulation from the end of each of the
conductor wires.
• All spliced wiring routed between Junction Boxes and controller must be soldered and encapsulated in
waterproof heatshrink.
1. Remove the Junction Box cover.
2. Route the 4-conductor cable through the fitting into the Junction Box farthest from the controller.
Connect wires from the cable to the TB1 terminal in the Junction Box:
Red or brown wire to +EX
White wire to +SIG
Black wire to -EX
Blue or yellow wire to -SIG
3. Route the cable through conduit to the next Junction Box. Estimate the required length of cable to the
terminal strip, allowing a little extra strain relief. Cut the excess cable. Connect wires from the cable to
the TB1 terminal in the Junction Box; see Step 2 for wiring.
4. Route another cable through the fititng into this Junction Box, and attach wires to the TB1 terminal; see
Step 2 for wiring.
5. Repeat Steps 3 and 4 until all Junction Boxes on the vessel are wired together.
6. Route the cable from the last Junction Box through conduit to the controller. Refer to the controller
maual for wiring the Junction Box to the controller. One vessel takes up one channel in the controller -
the channel shows the average value from all the sensors under the vessel.
