2.3 Junction Box Installation
Install the junction box in a convenient location, off from the floor, that is within 10' of the floor scale. See the junction box
manual.
2.4 Cable Connections
Each scale kit includes 20' of 6-wire cable to connect the scale to an indicator. The interface cable between the scale and the
indicator must be protected against crushing, cutting or moisture damage. See Figure 2-4 .
2.4.1 Junction Box Connections
1. Insert one end of the 20' cable into the junction box.
2. Connect the wires to the indicator terminal as shown in
Table 2-1 .
3. Pull out excess and tighten the strain relief bushing to hold the cable snugly.

4. Route the cable to the indicator considering the following:
• Load cell cables from the scale platform to the junction box should be protected with conduit.
• Leave a strain relief loop to facilitate future lifting of the scale for servicing or cleaning.
5. When the interface cable is in position, wire the cable to the indicator. See the indicator manual for correct wiring
arrangement.
