Principle
It is desirable to flatten any connection against equipotential exposed conducting structures in order to take advantage of the HF protection effects.
Using conductor cable runs leads to a satisfactory level of protection in most cases. As a minimum requirement, you should ensure that connecting cables between or inside buildings also have a ground connection: earthing cable or cable run.
For internal connections to cabinets and to machines, the cables shall be systematically flattened against the metal supports.
To maintain the correct protective effect it is advisable to observe a distance between cables of more than 5 times the radius "R" of the largest one:
