6.2.5 Reference potential
●
Provide a uniform reference potential in the entire installation and ground all electrical
appliances if possible.
●
Route your grounding conductors in a star configuration so that no ground loops can occur.
6.2.6 Equipotential bonding
The Installation of equipotential bondings are necessary if there are present or expected poten-
tial differences between parts of your application.

–
The impedance of 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 16 mm² to
withstand the maximum possible compensating current.
–
Equipotential bondings and shielded signal cables should be laid close to
each other.
–
Equipotential bondings must be connected to PE with low impedance.
