3.2 Air-termination rod
The air-termination rod with a diameter of 16/10 mm is screwed into the top of the lower part
of the air-termination rod ( Æ 22 x 4 mm) and the M 16 hexagon nut is tightened (see Fig. 3.2,
page 11).
The assembled air-termination rod is vertically inserted into the adapter of the brace frame and
the four M8 locking bolts are tightened (tightening torque of 15 Nm).
The four M8 hexagon nuts have to be tightened against the adapter (see Fig. 3.2, page 11).
3.2.1Discharge of lightning current
The air-termination rod is electrically connected to the profile roof via the brace frame and the
four conductor holders / clamps. Therefore, an additional down conductor (e.g. by means of a
round wire 8-10 mm) on or along the roof area is not required provided that the metal roof is
integrated into the external lightning protection system.
The metal roof is integrated into the external lightning protection system e.g. at the eaves while
maintaining the typical the down conductor clearances and is thus connected to the earthtermination
system.
