Legend:
1 Air-termination system
DIN EN 62305-3 (IEC 62305-3, VDE 0185-305-3) Section 5.2 must
be taken into account when planning the design of the air-termination
system. The height and arrangement of the air-termination system
must be designed in such a way that the objects to be protected are
located in the protection area.
2 Protection area
Along the whole of its length, the conductor must be located in the
protection area of the air-termination system. α = Protective angle
according to DIN EN 62305 (IEC 62305, VDE 0185-305-3).
3 Connection element
The connection element may only be connected to the air-termination
system or forwarding conductor of the external lightning protection.
4 Required separation distance to first potential connection
No electrically conductive or earthed parts may be located in the
area of the potential connection within the radius of the calculated
separation distance. These include metallic construction parts, con-
ductor brackets and reinforcements.
5 Potential connection
The potential connection must be installed in the manner described
in "6.6 Attaching the potential connection" on page 50. The po-
tential connection element must be connected to the equipotential
bonding with ≥ 6 mm² Cu or an equal conductivity.
6 Bend radius
When routing conductors, do not go below the minimum radii.
7 Additional potential connections
After the first potential connection using the potential connection
element, the isCon® conductor can be connected multiple times with
the earthed components of the structure, through which the lightning
current does not flow. See also "6.6.4 Installing additional potential
connections" on page 55.
8 Conductor fastening
The isCon® conductor must be fastened using the installation ma-
terial indicated. The maximum distance between the fastenings is
1 metre.
9 Separation distance of s ≤ 17 5 cm in air
A potential connection is not required for a calculated separation
distance of s ≤ 17.5 cm in air.
Note! B efore designing the lightning protection system, obtain information on
the function, general design and location of the structure.
Note! D uring routing in buildings, pay attention to the specified protection meas-
ures, e.g. division into fire sections. Read the OBO fire protection guide
(order no.: 9134859) for more information.
