6.3 Grounding

The system operator must ensure sufficient grounding of the support structures (substructures), particularly the coated components.
Safety regulations and country-specific directives for the grounding of electrical equipment (e.g., VDE/UVV/VBG4) must be followed.
The grounding of the support structure (substructure) must be taken into account for different applications:
Protection against electrical shock

Lightning protection

DANGER!
6.3.1

TN network

 In the TN network, ProfiDAT
transformer through a cable.
 The total impedance between the phase conductor and PE cable must not exceed 0.16 Ω.

Risk of death by electrical shock!
The support structure (substructure) can be under high voltage if it is not properly grounded
Contact with the support structure (substructure) can lead to death or severe injury. There is
also a high risk of injury from overreaction caused by electrical shock.
Therefore:
 Read and follow the locally applicable and international guidelines for proper
grounding installation and lightning protection.
 Provide the grounding installation that is appropriate to the architecture of the power
grid at the place of installation of the system (TT network or TN network).
 Connect the support structure (substructure) to the grounding installation.
 Install a conductive connection between all parts of the support structure
(substructure). Use toothed washers for screw connections or other suitable
components to establish a conductive connection between coated components.
 Regularly check that the support structure (substructure) is properly grounded.
