B.5 General information on the lightning protection equipment from the firm
of Dehn & Söhne
● When installing the modules read the instructions regarding the products from Dehn &
Söhne.
● If there is a fault in a lightning protection module, communication on the bus is interrupted
(cable shortcircuit). To reestablish communication temporarily (without lightning
protection) the protective modules can be removed from the base modules since these
function as throughconnected terminals without the protective module.
● The rest of the plant protection concept must be implemented complying with VDE 0185
Part 103.
