2 Intended use
The OBO isCon® system is a lightning protection system for the external
lightning protection of buildings and systems, which, in the case of direct
lightning strikes, can arrest the lightning surge currents into the earth,
thus protecting the building, the system and people against the impacts
of the lightning strike, e.g. fires, mechanical building damage and lethal
impulse voltage/currents.
The lightning protection system is not designed for extreme weather
conditions, such as continuous hail, snow or sandstorms. Such weather
conditions can seriously reduce the lifespan of the isCon® system.
The system is not designed for any other purpose than the one de-
scribed here. If the system is installed and used for another purpose, any
liability, warranty or damage claims shall be rendered null and void.
If you require information on the use of the OBO isCon® system for
something other than under the conditions of use described here, please
speak to your OBO contact.

Safety
3 Safety
3.1 General safety information
Observe the following general safety information:
– The work may only be carried out by lightning protection specialists
who have been trained for the installation of standard-conformant
lightning protection systems.
– If there is a lightning strike, lethal currents can flow through the light-
ning protection system. Never work on the elements of the lightning
protection system during a thunderstorm or if there is a risk of one.
– Lethal voltages can occur during the handling of electrical resources.
Never work on parts through which power is flowing. Wear suitable
protective clothing and comply with all the required safety guidelines.
– To install the OBO isCon® system, use only components of the OBO
product range, as otherwise there is no guarantee that safe installa-
tion is possible.
– The production method means that metallic objects may have areas
with sharp edges. Wear suitable protective gloves to avoid cutting
injuries.
– When erecting systems for maintaining electrical functionality, take
the necessary fire protection regulations into account. These in-
structions do not mention any fire protection standards which are
to be complied with. The OBO fire protection guide (article number:
9134859) provides more information on this. The conductor system
and any possible fire insulation must be matched.
– Take the risk of flooding, local fire prevention measures, accident pre-
vention regulations and rescue routes at the location into account.

System description
5 System description
5.1 Basic principles
Without any additional countermeasures, the high voltage pulses which
occur when there is a direct lightning strike will cause arcing on insu-
lation surfaces. This effect is termed a creep flashover. When the so-
called creep discharge inception voltage has been exceeded, surface
discharge is initiated, which can bridge a gap of several metres. To avoid
dangerous arcing between conductive parts (electrical systems, pipe-
lines, etc.), the maintenance of the separation distance is a key require-
ment when planning and implementing a lightning protection system.
These days, the roof level of building complexes is used as an installa-
tion area for air-conditioning, ventilation, transmission and energy collec-
tion systems, meaning that the structural features may be in the way of
the required spacing between the air-termination systems and the elec-
trical installations.
The isCon® insulated lightning protection system is used to maintain the
required separation distance. Depending on the design, after the first
potential connection behind the connection element on the air-termina-
tion rod, the isCon® conductor reflects an equivalent separation distance
of up to 0.45‒0.9 metres in the air or double that in solid matter. This
means that installation is possible directly on metallic and electric-
al structures. If there is a direct lightning strike, the incoming energy is
arrested through the isCon® conductor to the building's earthing system.
There is no direct arcing between the conductor and the building to be
protected.
The isCon® system is tested according to VDE V 0185-561-8 (IEC TS
62561-8) and has an arresting capacity of 150‒200 kA lightning surge
current (10/350 μs), depending on the conductor. It consists primarily of
the following components:
– isCon® conductor
– Insulated air-termination rods
– isCon® connection elements
– System accessories for fastening (tripod stand, support and holder)
– System accessories for connection

System description
5.2 isCon® conductor
According to DIN EN 62305-3/VDE 0185-305-3/IEC 62305-3, the insu-
lated isCon® conductor implements a separation distance of 0.45‒0.9
metres in the air and 0.9‒1.8 metres in the case of solid materials,
depending on the product design. The isCon® conductor is equipped
with an external semi-conductive jacket, allowing it to limit high lightning
voltage pulses against a reference potential by creating a connection
between the external semi-conductive jacket and the building's equipo-
tential bonding, which is not energised with lightning current, in the area
of the connection element.
The isCon® conductor is flame-resistant according to DIN EN 60332-1-2,
weather-resistant and halogen-free. It is suitable for routing in external
areas and can be routed on roofs, in walls, in concrete, in facade instal-
lations or in buildings.
The isCon® conductor is sold by the metre and in five variants:

Tab. 1: Product variants, isCon® conductor
The grey isCon® conductor is also suitable for routing in the earth. The
grey conductor was tested according to VDE 0185-305-3 (IEC/EN 62305-
3) with a pulse voltage of min. 100 kV (1.2/50 μs) in rain and can be used
up to a length of max. 5 m for touch protection. If the conductor is not
used as touch protection, then coloured painting, e.g. with facade paint,
is also possible. As the external grey jacket is non-conductive, it must be
removed in the contact areas.

5.4 isCon® connection elements
Using the isCon® connection element, you can connect OBO isCon® con-
ductors to forwarding systems, e.g. to the insulated OBO isFang air-ter-
mination rod system or to a separate ring conductor or earthing system
using a connection terminal. At the same time, an electrical connection
is created between the copper core and the black, weakly conductive
layer or protective jacket of the isCon® conductor. The grub screws in
the connection element are pre-coated with a reactive screw lock made
of two components. The components of the coating react automatically
on turning in and stick down the grub screws. If the screws are released
once more, the components are separated again and the grub screws
are locked again the next time they are screwed in. The screw lock is
fully hardened after six hours.
The isCon IN... connection elements allow the connection of internal
isCon® conductors in isFang air-termination rods.
The isCon ASE 23 and isCon ASE IN 23 possess an adaptive switching
element (ASE), which allows an insulation test.

System description
5.5 System accessories for fastening
Tripod stands (see section 5.5.1) or supports for wall or pipe mount-
ing (see section 5.5.2 on page 18) can be used to fasten the isCon®
air-termination rods. In addition, the system offers special holders for the
isCon® conductor (see section 5.5.3 on page 20).
5.5.1 Tripod stand
Fig. 6: Tripod stand with concrete blocks
The isCon® system contains folding tripod stands of different sizes, to
allow the isFang air-termination rods to be mounted on flat roofs, for
example. The tripod stands allow the erection of the air-termination rods
without penetrating the building structure with bolts/anchors.
Instead, the tripod stands are weighed down with FangFix concrete
blocks. The number of blocks required is dependent on the height of the
air-termination rod and the wind-speed zone.
Note! You can find further information on wind-speed zones in the OBO TBS
lightning protection guide (order no.: 9131970) and national directives.
The use of a tripod stand can compensate for a slope in the roof surface
of up to 5° (see also Fig. 44 on page 44). To protect the roof surface
and if there is the risk of softeners escaping from the roof film, it may be
wise to place a protective film/support mat under the concrete blocks of
the air-termination rod stand. We recommend contacting the roofer about
this.
Scope of delivery of the air-termination rod stand:
– Tripod stand
– Crossbar for potential connection with bolt, nut and lock washer
– Brief instructions

Tab. 4: Technical data of the tripod stands
The isCon® concrete blocks weigh approx. 16 kg and are screwed to the
bottom of the unfolded tripod stand. The blocks can be stacked to in-
crease the stand weight (e.g. for increased wind speeds) (see Fig. 8 on
page 17). Additional blocks can mounted internally in the tripod stands
of diameter 1,500 mm (unfolded).
