3. Air-termination rods for metal roofs<br />
The air-termination rods listed below (see table 3) are supposed to protect roof superstructures,<br />
dome lights, etc.<br />
The air-termination rods are dimensioned for wind speeds up to 145 km/h and 161 km/h<br />
(wind load zone II + III in accordance with DIN 4131).<br />
3.1Installation<br />
For mechanical stabilisation of the air-termination rod and protection against possible wind<br />
load effects, a roof conductor holder has to be installed on every brace end of the brace frame<br />
(hole with a diameter of 11 mm) (see Fig. 3, page 9).<br />
3.1.1 Roof conductor holders<br />
The roof conductor holders have to be specifically selected for the relevant roof profile e.g.<br />
standing seam, Part No. 365 059, or round standing seam, Part No. 223 010 (see Fig. 3, page<br />
9).<br />
The max. torque of 110 Nm for wind load zone II and 136 Nm for wind load zone III has to<br />
be observed!<br />
3.1.2Adjustment of the brace frame<br />
The brace frame has to be adjusted according on the profile clearance (230 to 520 mm) of<br />
the metal roof. For this purpose, the M16 hexagon nut below the brace frame is loosened.<br />
After that, the brace frame is adjusted according on the profile clearance (clearance of the<br />
seam edges) and placed on the seam edges of the roof profile (see Fig. 3, page 9).<br />
It is advisable to tighten the relevant four roof conductor holders on the seam edges of the<br />
profile. After that, the M16 hexagon nut below the brace frame is tightened. Observe the<br />
relevant tightening torques (see table 3 and Fig. 3, page 9).<br />
Note:<br />
When using these four roof conductor holders (clamps) for the relevant roof profile a lightning<br />
current carrying capability of 100 kA (10/350) is ensured.<br />
