2. See Figure 3-19 (conduited installation) or Figure 3-20 (non-conduited
installation). Route the 3-conductor cable through the fitting into the
junction box farthest from the signal processor. Connect wires from the
cable to the TB2 terminal in the junction box: black wire to B terminal, white
wire to W terminal, and red wire to R terminal. Connect the cable shield
wire to the Shield terminal between TB1 and TB2.
3. Route the cable through conduit/cable tray to the next junction box.
Estimate the 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: black wire to B terminal, white wire to
W terminal, and red wire to R terminal. Connect the cable shield wire to the
Shield terminal between TB1 and TB2.
4. Route another 3-conductor cable through the fitting into this junction box,
and attach wires to the TB2 terminal: black wire to B terminal, white wire to
W terminal, and red wire to R terminal. Connect the cable shield wire to the
Shield terminal between TB1 and TB2.
5. Repeat Steps 3 and 4 until all junction boxes for the vessel are wired
together.
6. Route the cable from the last junction box through conduit/cable tray to
the signal processor. Refer to the signal processor manual for wiring the
junction box to the signal processor. One vessel takes up one channel in
the signal processor — the channel shows the average value from all the
L-Cells on the vessel supports.
Note
SHLD screw is Shield Terminal Ground which is floating. Ground the
cable shield through the signal processor.

Notes:
• Verify that junction box PCB is 63-1170-01 (bottom center)
• L-Cells A and B are on one support leg.
• L-Cells C and D are on another support leg. L-Cells C and D can be wired as shown, or can be wired to its own
junction box (terminals A and B) if desired.
