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.
