Load Cell Wiring
Before the weigh module wiring can be completed, all load cell cable have to be routed through the conduit before beginning at
the load cell outlet. Use the following steps to route the load cell cables through conduit to the junction box.
1. Before routing load cell cables, mark each load cell cable at the end to help identify each load cell.
2. Working from the junction box corner (either pocket 2 or 4), insert a fish tape or similar tool and pull each load cell
cable through the rigid conduit until all access cable is taken in.
Figure 4-1. Load Cell Pocket Numbering
3. Wire each load cell to the junction box terminal strip in accordance with the wiring code contained in the Certificate of
Conformance (CC).
Load cell pockets are numbered to clarify wiring of load cells to the junction box (
).
4. The cable should not be routed near heat sources greater than 400
°
F (204
°
C). Do not shorten any load cell cable. The
load cell is temperature compensated with the supplied length of cable. Cutting the cable will affect temperature
compensation. Coil and protect excess cable so it will not be mechanically damaged or sit in water.
5. Provide a drip loop in all cables so that water or other liquids will not run directly down the cables onto either the load
cells or the junction box.
