Fig. 20 Earthing of the communication server in the case of an indirect cabling and direct cabling
Note
In the case of an indirection connection make sure that the communication server’s earthing
wire does not form any earth loops with the earthed cable screenings of the installation cables
leading up to the (main) distribution frame. The cables should be kept as short as possible and
laid out in parallel.
