8 Checking the lightning protection system
The entire lightning protection system must be tested according to DIN
EN 62305-3 (IEC 62305-3) and DIN EN 62305-3, Supplementary Sheet

Critical situations include structures containing sensitive systems, or
office and commercial buildings or places in which a large number of
people meet.
Note!
In the case of lightning protection systems in structures at risk of explo-
sion, we recommend carrying out a visual inspection every 6 months.
Carrying out a visual inspection
• Check that the black, weakly conductive layer of the isCon
®
conductor
is undamaged. An interruption of this layer will prevent the conductor
from functioning. In this case, replace the isCon
®
conductor.
• When using the isCon
®
Pro+ 75 GR conductors as protection against
touch voltages, check that the grey external jacket is undamaged.
Damage to this layer will prevent the conductor from functioning. In
this case, replace the isCon
®
Pro+ 75 GR conductors.
• Check that the protective jacket of the isCon
®
Pro+ conductors is
continuously present and has a material thickness of at least 0.2 mm.
In this case, replace the isCon
®
Pro+ conductor. The grey external
jacket may be interrupted and damaged. The protective jacket may be
damaged but must be continuously present.
• Check that the potential connection cables and all connection compo-
nents, in particular the potential connection elements, are undamaged.
There must be a low-resistance connection between all the elements.
If necessary, restore the flow.
• Check that the function of the holders and other mounting elements is
not impaired. If necessary, retighten the screws.
• Check that only products of the isCon
®
system, such as connection
elements, are used during mounting. Replace the parts which are not
components of the isCon
®
system with appropriate products of the
system.
• When using the isCon
®
Pro+ 75 GR conductor as protection against
touch voltages, check whether it is soiled. If this is the case, remove it.
