3.0 Wiring the Junction Box
All TuffSeal junction box models have been designed to connect and trim up to
four load cells per board. However, it is possible to use this box with other com-
binations. Use the expansion port on the main board (shown below), to connect
multiple junction boxes in series to accomodate applications that have more than
four load cells.
After determining the wiring pattern, route the load cell cables through the cord
grip assemblies and leave the grips loose until fi nal 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 accomodate 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. De-
termine 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.
