Load Cell Wiring; Db-Sp Wiring Color Code - Cardinal CenterPoint DB-SP Technical Manual

NOTE: Cardinal Scale Mfg. Co. recommends that the customer install protective conduit/cover
for the load cell cables whenever the condition is present that can result in damage or abrasion
to the load cell cables.
1. Route the load cell cables so they will not be damaged or cut. The cable should not be
routed near heat sources. 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 excess cable and protect it so it will not be damaged or sit in water.
2. Provide a dip 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 the load cell cable to the
structure, not the tank.
3. If conduit protection is necessary against mechanical or rodent damage to the load cell
cables, use flexible conduit and conduit adapters at the load cells.
4. Connect cables to the summing board in the junction box according to the illustration
shown on the next page and the labels on the terminal strips of the junction box. To verify
the wiring, refer to the documentation shipped with each load cell.
