EARTHING THE WEIGHED STRUCTURE

 

By means of a copper wire with suitable cross-section, connect the cell upper support plate with the 
lower support plate, then connect all the lower plates to a single earthing system. Electrostatic 
charges accumulated because of the product rubbing against the pipes and the weighed container 

walls are discharged to the ground without going through or damaging the load cells. Failure to 
implement a proper earthing system might not affect the operation of the weighing system; this, 
however, does not rule out the possibility that the cells and connected instrument may become 
damaged in the future. It is forbidden to ensure earthing system continuity by using metal parts 

contained in the weighed structure. 
 

FAILURE TO FOLLOW THE INSTALLATION RECOMMENDATIONS WILL BE CONSIDERED 

A MISUSE OF THE EQUIPMENT
