2.0 Mounting the Enclosure
The JB1010 has 4.0" x 8.75" mount-
ing centers for #10 or 1/4" screws.
Mount the en clo sure for proper
ser vice access. Avoid mounting on
weighbridges where vi bra tion and
shock loads may loosen con nec tions
and locations prone to fl ood ing.
The standard JB1010 has wa ter-
proof nylon cord grips to seal the
ca bles and pro vide strain relief.
Ca ble diameters from 0.157" to
0.314" can be used with these grips.
When in stall ing the cables into the
enclosure, leave the strain re lief
loose until the con nec tions have
been rout ed with the en clo sure ful ly
open. When com plet ed, tight en the
grips with a wrench to pre vent wa ter
from wicking into the box. To pre-
vent water and other contaminants
from entering the junction box, fi ll
any unused cable grips with post screw plugs; P/N 19538.
If cables will be exposed to fl uids, bend a short down ward loop in all cables near the cord grips so any fl uids
draining down the cables will drip off before reaching the junction box (see Figure 2-2).
Use a quality desiccant in the enclosure and replace it at least
every six months. Replace it more often if the en vi ron ment is
very damp or is regularly wetted down.
If using the transient protection grounding feature, install the
fi ttings with a wrench and use an electrical grade lubricant such
as WD-40
® on threads and fi ttings. Connect the ground lug to a
single system ground rod (if locally connected) or to the ground-
ing lug on the AC tran sient protector for the indicator or load cell power supply.
3.0 General Wiring Guide lines
The JB1010 is a universal trimming board, designed to trim almost any set of new or existing load cells in nearly
any confi guration. To properly wire the JB1010, fi rst determine what kind of application you have.
If the JB1010 is the only trimming junction box in a new system, continue on to the next page.
If the JB1010 replaces one or more boards in an existing system, skip to Section 8.0.
