The following points should also be observed:

•Close the parasitic circuit

•Connect all devices to the potential equalizing cable as often as possible. Electrical conductors such as machine elements, metal tubes or supporting constructions should be integrated into the system.

•Protect the potential-equalization cable and connections against corrosion.

•Select the cross-section of the potential equalization cable according to the maximum equalization current.

If these different measures do not correct the problem, a galvanic separation according to

ISO 9549 may have to be installed. You may also want to consider the use of fiber-optic cables.
