Metallic roof parapet
If there is a metallic roof parapet
1
which is used as a natural com-
ponent of the lightning protection system, the isCon
®
conductor can be
connected 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
, provided that the potential connection clip
3
is mounted, creat-
ing the electrical connection between the black, weakly conductive layer
or the protective 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 conductor type isCon BA 45 SW (Basic) can be routed with or with-
out potential connection. If the conductor is routed without a
potential connection, observe “Mounting variant 2 for isCon BA 45 SW”
on page 54.
