Improving the grounding (EMC), HF grounding
For improved, low-impedance grounding at high frequencies, we recommend using
the following connections with corrosion protected connection elements:
HF grounding is not installed as standard.
The HF grounding option can be combined with LF grounding at the terminal box.
If you require LF grounding in addition to HF grounding, you can connect the con-
ductor to the same point.
The HF grounding option can be ordered as follows:
•
Completely pre-assembled at the factory
•
As "grounding terminal" kit for customer installation; part numbers listed in the fol-
