isCon
®
conductor included in the ring conductor
In areas in which a conventional ring conductor would be difficult to
install whilst maintaining the required separation distance (s) (e.g. to
roof structures) (see Fig. 70 No.
2
), the isCon® conductor
1
can be
integrated into the mesh, provided that the calculated separation distance
is less than or equal to the equivalent separation distance of the isCon
®
conductor used.

Protection against touch voltages
The isCon
®
conductor Pro+ 75 GR can be used as protection against
dangerous contact voltage. This is particularly required in areas with
groups of people. The isCon
®
conductor Pro+ 75 GR was tested up to a
length of max. 5 m with a pulse voltage of min. 100 kV (1.2/50 μs) in rain
and fulfils the requirements for protection against touch voltages accord-
ing to VDE 0185-305-3 (IEC/EN 62305-3).
WARNING
Risk of electric shock!
Energised parts
Replace metallic rain gutters, in direct proximity to the isCon® conductor
Pro+ 75 GR, with plastic pipes.
ATTENTION
Risk of damage!
When used as protection against contact voltage:
- The grey external jacket may not be damaged.
- Painting (e.g. with facade paint) of the grey external jacket is not permit-
ted.
