3. Air-termination rods for metal roof
3.1
Installation
For mechanical stabilisation of the air-termination rod and protection against possible wind load ef-
fects, a roof conductor holder has to be installed on every brace end of the brace frame (hole with a
diameter of 11 mm) (see Figure 6 on page 10).
3.1.1 Roof conductor holders
The roof conductor holders have to be specifically selected for the relevant roof profile e.g. standing
seam, Part No. 365 059, or round standing seam, Part No. 223 010 (see Figure 6 on page 10).
Tilting moments (due to wind load) are available on request!
3.1.2 Adjustment of the brace frame
The brace frame has to be adjusted according to the profile clearance (230 to 520 mm) of the metal
roof. For this purpose, the M16 hexagon nut below the brace frame is loosened. After that, the brace
frame is adjusted according to the profile clearance (clearance of the seam edges) and placed on the
seam edges of the roof profile (see Figure 6 on page 10).
It is advisable to tighten the relevant four roof conductor holders on the seam edges of the profile. After
that, the M16 hexagon nut below the brace frame is tightened. Observe the relevant tightening torques
(see Table 2 and Figure 6 on page 10).
Note:
When using these four roof conductor holders (clamps) for the relevant roof profile, a lightning current
carrying capability of 100 kA (10/350 µs) is ensured.
