Due to building acceptance: does this comply with the DIN standard for electrical?

Perhaps someone knows whether this rather amateurish installation for LAN and SAT complies with the DIN standard (see attachment).

The keyword equipotential bonding has already been mentioned, but not in relation to the satellite antenna. Whether the IuK and RuK cables were installed as required to be strain-relieved and replaceable, and whether the requirement for empty conduits between the attic and basement is met, cannot be seen from the pictures.

According to DIN EN IEC 60728-11 (VDE 0855-1):2023-10, which is primarily responsible for antenna safety, the equipotential bonding must be maintained on the shields of all coaxial cables even when the multiswitch is removed. This requires grounding blocks or a grounding angle, none of which can be seen. If the 4 LNB cables were exceptionally connected norm-compliantly to the antenna mount of a grounding-required antenna "close to the mast" after entering the building, at least protection against electric shock would be fulfilled.

It is positive to note that modern compression connectors were used instead of F-threaded connectors that damage the braid. How grounding and equipotential bonding should look according to IEC 60728-11 can be seen from the example picture. The depicted outdoor down conductor and support ground are optional and not mandatory. However, it may take a long time before it becomes common knowledge among certified electricians (EFK) that not only the grounding conductors but also the connectors and surge arresters (HES/PAS) must be capable of carrying lightning currents.

Or would that have to go in the box?

Formally yes, but this was conceived by the employees in the responsible national NABau committee without consulting the DKE colleagues responsible for antenna technology. Therefore, example pictures with headend units in the attic are still included in the international IEC 60728-11 and its national derivatives.

Mounting the multiswitch next to the network components also makes media consolidation possible.

Dear *Dipol*, thank you very much for the detailed and competent response. That really helps me for the upcoming acceptance. Best regards Uli

Hello Uli,

then I will pass on the earnest hope that there are no, unfortunately common, ignorance and disregard of [DIN 18014] in your new building.

Best regards Roland
