Metallic roof parapet
If there is a metallic roof parapet
1
which is used as a natural compo-
nent of the lightning protection system, the isCon
®
conductor can be con-
nected to it using a suitable OBO connection component
2
.
The potential is connected to the protective equipotential bonding on the
air-termination rod via the potential connection clip
3
(type 927 2 6-K).
Alternatively, the potential can be connected at the air-termination rod
stand
4
, providing that the potential connection clip
3
is mounted,
creating the electrical connection between the outer jacket of the isCon
®
conductor and the air-termination rod.
The distance x (= separation distance s multiplied by two) between the
potential connection terminal
5
and the rear connection element
6
should be noted.
Note!
The isCon conductor, type BA 45 SW (Basic), can either be installed with
or without a potential connection. If the conductor is installed without a
potential connection, the distance x must be maintained between the con-
nection element and the last insulated spacer and from this last spacer
in the direction of the other end of the conductor. Within the calculated
separation distance s, there must be no electrically conductive parts.
