Lightning protection
▪
Electrical installations must be protected against overvoltage (compulsory since
14 December 2018) (see DIN VDE 0100-443 (IEC60364-4-44:2007/A1:2015,
modified) and DIN VDE 0100-534 (IEC 60364-5-53:2001/A2:2015, modified).
Whenever modifications are made to existing installations, retrofitting a surge
protective device (SPD) in accordance with VDE is mandatory.
▪
A maximum cable length of 10 metres should not be exceeded between the
surge protective device (usually type 1, internal lightning protection) installed at
the service entrance and the equipment to be protected. For longer cables,
additional surge protective devices (type 2) must be provided in the sub-
distribution board upstream of the equipment to be protected or directly in the
equipment itself.
▪
The associated lightning protection concept must be provided by the operator or
by a suitable provider commissioned by the operator. Surge protective devices
can be offered for the control units on request.
