Critical situations include structures containing sensitive systems, or

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 semi-conductive jacket of the isCon cable is undam-
aged. An interruption in the external black conductive layer will prevent
the cable from functioning. In this case, replace the isCon cable.
• Check that the connection elements for the isCon cable are tight. If
necessary, retighten the screws.
• 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.
