The air-termination rod is suitable<br />
for installing ”isolated<br />
air-terminations” in accordance<br />
with IEC/EN 62305-3<br />
(VDE 0185-305-3). When<br />
using the air-termination rod,<br />
the ”protective angle method”<br />
has to be applied.<br />
The protective angle a depends<br />
on the class of LPS (lightning<br />
protection level) and the height<br />
of the air-termination rod above<br />
the reference plane.<br />
For more detailed information<br />
on these values, see IEC/EN<br />
62305-3 (VDE 0185-305-3),<br />
Table 3 (see also Table 1 and<br />
Fig. 1).<br />
The rolling sphere method can<br />
also be used for positioning<br />
the air-termination rod.<br />
The air-termination rods specified<br />
in these installation instructions<br />
are designed up to<br />
wind load zone III in accordance<br />
with DIN 4131.<br />
If installed properly, airtermination<br />
rods can withstand<br />
wind speeds up to 161<br />
km/h.<br />
