Lightning protection
▪
Electrical installations must be protected against overvoltage (binding since
14 December 2018) (see DIN VDE 0100-443 (IEC 60364-4-44:2007/A1:2015,
modified) and DIN VDE 0100-534 (IEC 60364-5-53:2001/A2:2015, modified). Every
time the existing installation is modified retrospectively, overvoltage protection
to VDE must be retrofitted.
▪
The maximum cable length between the surge arrester (usually type 1, internal
lightning protection) at the point where electricity enters the building and the
device to be protected should not exceed 10 m. For longer cables additional
surge arresters (type 2) must be fitted in the upstream sub-distribution system or
directly in the device to be protected.
▪
The lightning protection concept must be provided by the operator or by a
suitable supplier contracted by the operator. The corresponding protective
equipment for the control units / switchgears can be offered on request.
