Shield connection 
● Do not use cable shields to conduct current. It is not permissible that the cable shield is used 
as neutral or PE conductor.
● Apply the cable shield so that it covers the greatest possible surface area. Use ground 
clamps, ground terminals or ground screw connections.
● Avoid extending the cable shield to the grounding point using a wire. This reduces the shield 
effectiveness by up to 90%.
