The grounding issue is of major importance for shielding against low frequency

While high frequency shielding is also feasible and reliable without grounding.  Low frequency inductions should in this case be avoided, for instance by installing a demand switch.

rounding measures should not be underestimated! Please carefully read the detailed descriptions and instructions sent along with any grounding component. Grounding measures are to be executed by experts listed by your carrier only! The executing expert is liable for any grounding steps taken!

The following points are to be taken into consideration:

• Protective measures against shock currents according to DIN 57100/VDE 0100 part 410 + part 540, grounding according to DIN/VDE 0100 part 410 + part 540, sight check and function control according to DIN/VDE 0100 part 610 par. 4+5 and EMV according to VDE 0100.
• Grounding is only permissible in a TNS or TT-net! Never and in no case implement grounding in network configurations with a combined PEN conductor!
• The installation of a fault current circuit breaker (FI/RCD) of less than 30 mA is compulsory.

Preferable order of grounding: 

• With a 4 mm² cable (16 mm² for facade shielding) ideally directly on the potential equalization.
• With a 2.5 mm² cable directly on the PE conductor within the electrical installation, for instance using the grounding plug EPS (also included in the grounding set ESW+)  on a socket (often feasible solution for indoors).
• On a heating pipe connected to the potential equalization (alternative solution) - check for low impedance!
