The two (2) cables from the two (2) center section boxes will enter the 14478

14478 Instrument SVP as well. Prepare the cable ends in the standard manner.
Use Appendix II for wiring instructions of all pit balance boxes. Connect the indicator
interface cable to the instrument in the scale house per the instructions in the
appropriate indicator service manual.

Note: The Full Electronic scales have been designed to provide protection from the effects
of moisture. The load cells have been calibrated with the cable attached and
therefore the cable should NOT be cut. The cable is connected directly to the
balance box or SSC through a sealed bushing which MUST be tightened properly to
keep water/moisture out of the box. All cabling should have a drip loop at the cell or
box entry location to help prevent water entry. On all boxes, particularly stainless
steel, the black plastic fittings have "O" rings that can be forced out of position if the
bushing itself is not tight. To prevent this, first tighten the inner nut securing the
bushing in the hole, then insert cable and carefully tighten the gland until it is very
snug. Do not over-tighten where bushing turns. Secure the cover.
Note: Balance Boxes must have one (1) ground rod in the pit for proper grounding.
~Caution~
Inadequate grounding will prevent the surge voltage protection from functioning properly.
