2 Wiring the Junction Box
The JB104SS junction box model has been designed to connect and trim up to four
load cells per board. However it is possible to use this box with other combinations.
Use the expansion port on the main board (shown below), to connect multiple junction
boxes in series to accommodate applications that have more than four load cells.
Figure 2: Expansion Port Location
After determining the wiring pattern, route the load cell cables through the cord grip
assemblies and leave the grips loose until final closure. Before connecting load cell
wires to the terminals, strip the wire insulation back 1/4" to expose the wire. The
spring-loaded terminals will accommodate 12 to 28 gauge wire. To connect the load
cell wires to the appropriate connectors, push in the quick-connect lever with a small
screwdriver. While holding in the lever, insert the appropriate wire into the exposed
wire opening. Release the screwdriver to allow the spring-loaded gate to close and
lock the wire in place.
The indicator terminal strip is used to connect the main cable to the indicator.
Determine the
indicator’s load cell input connections from the operating manual. Run a
cable from your indicator terminal into the junction box through the larger cord grip and
make the connections on the indicator terminal using the same procedure as inserting
load cell cables to the appropriate connectors.
