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.
