Wherever possible, exterior cabling should be installed on metallic cable
trays. A galvanic connection must be provided for joints between cable
trays.
You must abide by the applicable lightning protection and grounding
regulations when installing exterior cables.
Attention!
Where cables and signal lines for PLC equipment are installed outside of
buildings, the conditions for internal and external lightning protection must
be satisfied.
•
Exterior lines should either be installed in metallic conduit pipes that is
grounded on both ends or in steel-reinforced concrete cable trunks with
continuously connected reinforcing.
•
Signal lines should be protected against overvoltage by varistors or by
lightning arrester filled with rare gas.
•
Install these protective elements at the location where the cables enter
the building.
Note!
Any lightning protection system must be based on an individual
assessment of the entire plant. For questions please contact VIPA GmbH.
