Equipotential Bonding

  • Install sufficiently dimensioned equipotential bondings, if potential differences are present or have to be expected in your application between different parts of the installation.
  • The impedance of a equipotential bonding must be equal or lower than 10 % of the shield impedance of the shielded signal cables between the same points.
  • The conductor cross section of a equipotential bonding must be able to withstand the maximum possible compensating current. By experience, a conductor cross section of 16 mm² has proven to be sufficient.
  • Equipotential bondings and shielded signal cables should be laid close to each other. This prevents coming up inductive loops in which disturbances could be induced.
  • Equipotential bondings must be connected to PE with low impedance.
