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 interception 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 22).
– Calculate the number of isCon cables and interception systems ac-
cording to the lightning protection class and required cable length (see
„4.3 Cable lengths and lightning protection classes“ on page 22).
– Additional measures are required for installations in potentially ex-
plosive areas (see „4.4 Installation in potentially explosive areas“ on
page 24) and on soft-covered roofs (see „4.5 Soft-covered roofs“ on
page 26).
– When erecting interception rods, take the appropriate wind speed
zone into account (see „4.6 Installation in different wind speed zones“
on page 27).
– Ensure that there is equipotential bonding (see „5.7 Attaching the
potential connection“ on page 50).
