Make sure that the RF reference ground is not impacted by disturbance voltages (e.g. 
from an industrial network) when the protective earth conductor is connected to the 
protective earth. If this is the case, the protective earth must be connected via a PE 
choke. With the choke, make sure that no voltages constituting a shock hazard are 
applied to the housing. 

 

4.5.1  Avoiding Grounding Loops 

To avoid grounding loops, the V-network should be grounded only once in the test 
setup, if possible. An example of using a PE choke was already given above (ensuring 
that the RF reference ground is not impacted by disturbance voltages from an 
industrial network).

Arrangement of PE chokes to avoid grounding loops 

PE chokes for currents up to about 30 A are common. In case of higher currents, you 
can make them yourself by using ferrite toroidal cores. The following rule applies: In 
case of a short circuit, the voltage drop at the PE choke must not exceed 4 V.
