See Figure 3-6. Hold the junction box at the
desired mounting location. Mark the four
mounting holes.

Wiring Load Discs to Junction Box
See Figure 3-7. The stainless steel junction box accommodates up
to eight Load Discs, with up to two Load Disc wires at each
terminal. Note that the junction box has no pre-cut holes for conduit
or fittings. Follow this procedure:
1.
Install liquid tight fittings.
2.
Seal fittings with Sikaflex™ or electrical grade
sealant.
3.
Thread the Load Disc cable through the desired conduit
fitting. (See Figure 3-7).
4.
Estimate the required length of cable to the terminal strip,
allowing a little extra for strain relief. Cut the excess cable.
5.
Strip back 3” (76mm) of the cable sheathing to expose the
four wires and the shield inside. Strip back
1
/4” (6mm) of
insulation from the end of each of the wires.
6.
Connect the Load Disc wires to the selected TB2-5
terminals on the left side of the junction box:
red or
brown wire to +EX
, white wire to
+SIG
, and black
wire to
-EX
, and blue or yellow wire to
