In principle, fitters and operators have to observe the national installation directives and/or those superceding them.


Alternative ways to connect the cable screen are available for EMC interference but they must conform to national installation directives and/or those superceding them.





The Ex-e connection box has a screen connection rail for the alternative screen connection solution. In this case, the cable screening can be extended by a short wire (minimum diameter 1.5mm²) and connected to the clamping screws.

This equipotential bonding connection part is, as mentioned above, internally connected with the GND supply cable (X1 pins 3 and 4).
