Connect the Grounding Cables

Connect the grounding cables from each load cell to the threaded cable stand-off on the weighbridge. Addition

-

ally, connect a grounding cable from the M8 bolt/nut on the locating plate to the same stand-off on the weigh

-

bridge.

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.

Grounding Cable Stand-Offs

Load Cell Cable Wiring

At this point all of the load cell cables can be 

pulled through the installed conduit.

Depending on the length of your scale, find 

the correct wiring diagram on the following 

pages. Additionally, a wiring diagram was 

included with your “scale package” along with 

the foundation drawing.

It is important that all cables be installed so 

that they do not touch the ground and are 

internal to the scale. Zip tie all excess cable 

and attach to hangers near the junction box.

Your digital Pit Style “scale package” will 

include all load cell cables, junction box(es), 

grounding cables, ground rod, indicator, and surge protection device.

Your analog Pit Style “scale package” will include all load cell cables, junction box(es), grounding cables, 

ground rod, and surge protection device. It does not include an indicator. 

Be sure that the cables are not run or bundled so tight that they cause the scale modules to bind resulting in 

weight variations. After being run, connect all load cell cables to the load cells. 

Note: Do not cut the load cell cables—this will void the warranty.
