2.5 Junction Box Connections
The indicator terminal strip is used to connect the main cable to the indicator which is shown in Figure 2-3
Determine the indicator’s load cell input connections from the operating manual. Run a cable from your indicator
terminal into the junction box and make the connections. The following table shows the correct junction box
connections using the cable color code.

2.5.1 Electrical Interface to Indicator
Twenty feet of 6-wire cable to connect the scale to the weight indicator is supplied with each scale. The cable must
be routed to the indicator in a manner that will protect the cable from damage. Two methods of cable protection in
non-washdown applications are shown. When planning cable routing with either of these two methods, leave a
loose coil of excess cable under the scale to facilitate future lifting of the scale for servicing or cleaning.
