Field of application according to EN 1991 T 1-3
Anchor Fmax: type S / type P 1.875 kN
Wind load: based on the design loads according to EN 1991 T 1-3, the following minimum distances among collectors must be respected:
1. The smallest value of 1/10 of the building length (eaves length) or 1/5 of the building heigth with respect to eaves and ridge.
2. The smallest value of 1/10 of the building width (gable width) or 1/5 of the building height with respect to side edges.
If extension kits are used, make sure that the roof hooks are positioned in the middle at equal distances. With an elevation above
900 HH [m] and roof angles below 40°, starting from snow load zone 2 a specific static calculation must be made.
