Planning an installation
When planning the lightning protection of buildings, we recommend taking
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
tems according to the lightning protection class and required con-
ductor length (see "4.3 Conductor 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 "6.6 Attaching the
potential connection" on page 50).
