Lightning protection class I
The mounting example shows a better division of the lightning current to
two isCon
®
conductors through the use of an isFang air-termination rod
with two external conductors
1
and
2
. The isCon
®
conductors are run
on two separated ring conductors
3
and
4
, which are run on opposite
sides of the building. Alternatively, the air-termination system can be
implemented with a single isCon
®
Premium conductor in lightning protec-
tion class 1.
The potential connection clip
5
(type 927 2 6-K) must be mounted,
in order to create an electrical connection between the black, weakly
conductive layer or protective jacket of the external isCon
®
conductor and
the air-termination rod. The potential is connected here. Alternatively, the
potential can be connected at the air-termination rod stand
6
, provided
that the potential connection clip
5
is mounted.
The distance x (= separation distance s multiplied by two) between the
potential connection terminals and the rear connection elements should
be noted.
