About these instructions
1.4 Correct 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 possibly
lethal voltages and current pulses.
The system is not designed for any other purpose than the one described
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 some-
thing other than under the conditions of use described here, please speak
to your OBO contact.
1.5 Declaration of conformity
Lightning protection components are not subject to an EU directive.
Instead, OBO makes the manufacturer's declarations of conformity avail-
able for the appropriate components of the lightning protection systems.
These declarations of conformity certify the agreement with the named
standards and stored documents, but do not, however, contain any guar-
antee of properties.
You can find individual proofs for lightning protection components on the
OBO web pages (www.obo-bettermann.com).
1.6 Basic standards

General safety information
2 General safety information
Observe the following general safety information on handling the OBO
isCon® system:
• 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.
Therefore, 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 installation
is possible.
• Only the jacketing of the grey OBO isCon® conductor may be painted a
different colour, as it does not possess any electrical properties which
could be at risk from paint.
• The production method means that metallic objects may have areas
with sharp edges. Wear suitable protective gloves to avoid cutting
injuries.
• When erecting function maintenance systems, take the necessary fire
protection regulations into account. These instructions do not mention
any fire protection standards which are to be complied with. Read the
OBO fire protection guide (article number: 9134859) for more informa-
tion.

Product description
3 Product description
3.1 Basic principles
Without any additional countermeasures, the high-voltage pulses which
occur when there is a direct lightning strike will cause arcing to insula-
tion 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, pipelines, etc.), the
maintenance of the separation distance is a key requirement when plan-
ning and implementing a lightning protection system.
These days, the roof level of building complexes is used as an installation
area for air-conditioning, ventilation, transmission and energy collection
systems, meaning that the structural features may be in the way of the
required spacing between the air-termination systems and the electrical
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-termination
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 electrical 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 down-conductor and the building to be protected.
The isCon® system has a tested arresting capacity of 150‒200 kA light-
ning surge current (10/350 μs). It primarily consists of the following com-
ponents:
– isCon® conductor
– Insulated air-termination rods
– System accessories for fastening (air-termination rod stand, support
and holder)
– System accessories for connection
3.2 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 mater-
ials, 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 be-
tween the external semi-conductive jacket and the building's equipotential
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 installa-
tions or in buildings.

The metallic components of the rods are made of aluminium and stainless
steel (V2A). The insulated central rod is made of glass-fibre-reinforced
plastic (GRP) and allows sufficient spacing of the arresting components
(connection element at the bottom end of the air-termination rod) to all
roof structures. In addition, it guarantees a sufficient distance of 1,500 mm
to the equipotential bonding, which is connected at the bottom end of the
insulated rod (see also Figure 13 No.

3.4 System accessories for fastening
Air-termination rod stands (see section 3.4.1) or supports for wall or pipe
mounting (see section 3.4.2) can be used to fasten the isCon® air-temin-
ation rods. In addition, the system offers special holders for the isCon®
conductor (see section 3.4.3).
3.4.1 Air-termination rod stand
Figure 6: Air-termination rod stand with concrete blocks
The isCon® system contains folding air-termination rod stands of different
sizes, to allow the isFang air-termination rods to be mounted on flat roofs,
for example. The tripod air-termination rod stands allow the erection of the
air-termination rods without penetrating the building structure with bolts/
anchors.
Instead, the air-termination rod 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 air-termination rod stand can compensate for a slope in the roof
surface of up to 5° (see also Figure 48 on page 44). To protect the
roof surface, it may be wise to place a protective film under the concrete
blocks of the air-termination rod stand. We recommend contacting the
roofer about this.

Planning an installation
4 Planning an installation
When planning the lightning protection of buildings, we recommend tak-
ing the following aspects and possible activities into account:
– Determine the protection area, the required height and the arrange-
ment of the air-termination rods, according to DIN EN 62305-3 (IEC
62305-3, VDE 0185-305-3).
– Calculate the necessary separation distance (see “„4.2 Calculating,
checking and maintaining the separation distance“ on page 23).
– Calculate the number of isCon® conductors and air-termination sys-
tems according to the lightning protection class and required cable
length (see “„4.3 Cable lengths and lightning protection classes“ on
page 23).
– Additional measures are required for installations in potentially ex-
plosive areas (see “„4.4 Installation in potentially explosive areas“ on
page 25) and on soft-covered roofs (see “„4.5 Soft-covered roofs“
on page 27).
– When erecting air-termination rods, take the appropriate wind speed
zones into account. You can find further information in the OBO TBS
lightning protection guide and national directives.
– Ensure that there is equipotential bonding (see “„5.6 Attaching the
potential connection“ on page 49).
Note: You can find additional detailed planning aids on lightning and surge pro-
tection systems in the OBO TBS lightning protection guides (order no.:
9131970).
Note: To guarantee the functionality of the isCon® lightning protection system,
tested components of the OBO delivery range must be used.
