Connect the Grounding Cables 

 
Connect the grounding cables from each load cell to the threaded cable stand-off on 
the weighbridge. Additionally, connect a grounding cable from the M8 bolt/nut on the 
locating plate to the same stand-off on the weighbridge. 
 
Adjacent weighbridges require an additional grounding wire from the threaded stand-
off on the weighbridge which is run to a stand-off on the next weighbridge in line.
