Mounting Trim Box
1. See Figure 3-9. Hold the junction box at the desired
mounting location. Mark the four mounting holes.
2. Mount the junction box with #8-32 socket head cap
screws and flat washers. Tighten the
screws until snug.
Wiring Load Discs to Trim Box
See Figure 3-10. The summing stainless steel junction box accom-
modates up to eight Load Discs. Follow this procedure:
1. Thread the Load Disc cable through the desired conduit
fitting. (See Figure 3-10).
2. Seal fittings with Sikaflex™ or electrical grade
sealant.
3. Estimate the required length of cable to the terminal strip,
allowing a little extra for strain relief. Do not cut the excess
cable.
4. 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.
5. The trim box is designed for two, three or four load cells.
Determine the number of load discs that will be wired
to the trim box, and cut the JU jumpers for any unused
inputs. The wire coding for the load disc:
Red or Brown = +EX
Black = -EX
White = +SI
Blue or Yellow = -SI
6. Wire each load disc to the terminals, leaving the cord grips
loose until the trimming has been complete. The terminals
have quick connect levers that open when pushed. A
screwdriver or ballpoint pen can be used to open or close
jaws. The terminals can accommodate wire gauges #14
through #26.
7. Set all the potentiometers fully clockwise for inputs being
used. This will give the maximum output from each
load disc.
