The power connections are voltage fixed up to max. 4kV(L+N) according to VDE, additio-
nal measures against overvoltage in operational conditions are not necessary. Measures
for lightning protection in the building should be applied as usual (coarse protection).
Note:
As always with electronic, suppressor elements (e.g.VDR´s) are to be planned with coils
from 230V~ contactors and relays, that are installed in the same distribution boxes as the
LCN modules.
