The use of a 6 wire shielded cable is recommended in order to reduce
weighing error. (When using a 4-wire cable, connect pin # 34 to # 35, and
pin # 36 to # 37.)
If the system requires two or more load cells, use an explosion-protected
type of summing box to input the signal into the indicator.
Use a shielded cable and connect its shield to pin # 40 (Frame ground).
