2.
Thread the Load Disc cable through the desired conduit
fitting. (See Figure 3-8).
3.
Estimate the required length of cable to the terminal strip,
allowing a little extra for strain relief. Cut the excess cable.
4.
Strip back 3” (76mm) of the cable sheathing to expose the
three wires inside. Strip back 1/4” (6mm) of insulation from
the end of each of the wires.
5.
Connect the Load Disc wires to the selected TB3 terminals
on the left side of the junction box: brown or red wire
to R, white wire to W, and black wire to B.
6.
Perform Steps 2 through 5 for each Load Disc you wire to
this junction box. Up to two Load Discs can be wired to
each terminal.
7.
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™ 3-conductor shielded interconnect cable or
equivalent to wire junction boxes together and to the signal
processor. For lengths up to 1,000’ (305m) use 18-gage
Belden™ 8791 cable. For lengths from 1,000’ to 2,000’ (305m to
610m) use 16-gage Belden™ 8618 cable.
4.
When wiring cable to junction box terminals, strip back 3”
(76mm) of cable sheathing to expose the three conductor wires
and shield wire inside. Strip
1
/
4
” (6mm) of insulation from the
end of each of the conductor wires.
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 3-9. Route the 3-conductor cable through the fitting
into the junction box farthest from the signal processor.
Connect wires from the cable to the TB1/TB2 terminal in the
junction box: black wire to B, white wire to W, and
brown or red wire to R.
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 for strain relief. Cut the excess cable.
Connect wires from the cable to the TB1/TB2 terminal in the
junction box:
black wire to B, white wire to W, and
brown or red wire to R.
Note: Ground the cable
shield only at the signal
processor.
