3. Load Cell Wiring
1. Route the load cell cables so they will not be damaged or cut. Cable should not
be routed near heat sources greater than 150 °F. 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 be sitting in water.
2. 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. Attach load cell
cable to the dead structure, not the vessel.
3. If conduit protection is necessary against mechanical or rodent damage to the load
cell cables, use fl exible conduit and conduit adapters at the load cells.
4. Connect cables for load cells to the summing board in the junction box according
to the guide shown below and the labels on the terminal strips of the junction box.
To verify the wiring scheme, see the certifi cation shipped with each load cell.
5. For better performance, use positive and negative remote sense lines if the wiring
running from the junction box to the indicator is longer than 25 feet.
