Ground cable

4.1

Technical Description

4.1.1. Application Range

The ground cable is used for protecting the load cells from unwanted currents. These
currents could be cause by e.g.:

as equalization currents for missing or faulty, voltage equalization lines,

a lightning bolt in the vicinity,

welding or

static discharge.
The ground cable is an electrical shunt for the load cell and mounting unit. High welding
currents can damage load cells, mounting units or the electronics. Voltage spikes from
static discharge can damage the electronics.
Fig. 4-1 Application example Ground Cable

4.1.2 Construction

The ground cable consists of a fine-strand copper wire with a cross-section of 50 mm
two eyelets, Ø 10mm.
4.2

Assembly

A permanent screw-contact is to be made for fastening the ground cable, e.g. M10, on the
loading platform and the foundation.
