Fitting The Various Mounting Systems - IBC TopFix 200 Installation Manual

04. Fitting the various mounting systems

4.1 General dimensioning information
The PV system on your roof is subject to considerable forces caused by snow and, most of all, wind.
Improper fastening of the PV system, particularly the modules, may cause significant damage to objects as
well as personal injury. For this purpose, it is crucial you observe the following section.
The number of fixing points on the roof is always dependent on the particular design of the roof, building
height, roof pitch, the wind and snow load zone and a large number of other factors.
The compatibility of the material pairings between the roof and the PV system must be checked before the
instalation.
Edges and corner areas must be particularly taken into account as per EN 1991-1-4 (Euro code 1) as
increased loads may apply due to wind dynamics, depending on the building type. For more detailed
information, please see the graphical indications of fixing points in our PV Manager software. Calculate
and verify any specific details according to the applicable standards. In this process, we recommend you
consult a structural engineer.
Before starting installation, the existing wooden substructure must be checked for sufficient stability. The
wooden substructure must have a service life of more than 20 years. In case of doubt, consult a roofer or
joiner and a structural engineer.
As a rule, verify on-site static conditions and whether or not the outer roofing in conjunction with the
substructure (steel beams/purlins) is able to bear the additional pressure and dynamic loads of the PV
plant.
We shall not assume any system liability for the integrity of the roof as this mainly depends on the quality
of mounting or subsequent sealing procedures. The rules of the building trade as well as guidelines and
instructions of the roofing manufacturer are to be observed. Mounting system parts must not be treated
with additional anti-corrosion protection in normal, atmospheric conditions (corrosivity categories C1-C3
according to EN ISO 12944-2 and surrounding temperatures of -30°C to +50°C). Take additional, suitable
anti-corrosion protection measures in the event of other assembly locations (e.g. contact with grit, direct
vicinity to the coast, acidic or alkaline environments).
Modifications that are not permitted and improper use of our components during assembly and
construction shall render and liability and guarantee claims void.
