Laying the cables
Starting with the frame installation, several points concerning the direction of power lines and laying of
cables should be observed.
To avoid overvoltage couplings from lightning strikes, the resulting conductor loop must be kept to a
minimum.
Routed cables must not obstruct any potential snow and ice from sliding down.
Water must not collect around routed cables, ensure continuous water drainage.
Route cables with maximum possible UV and weather protection.
Dimensioning
Our TopFix 200 mounting system is dimensioned using our very own PV Manager software, used to
determine the degree of utilisation and hence the suitability of the components to be mounted on your roof.
The software is designed as a planning tool. It does not substitute official, static calculations.
If you do not have the PV Manager available for PV plant dimensioning, please contact your responsible
sales representative to determine and dimension the mounting system.
Important!
Any calculations for the roof construction as well as any existing superstructures do not form part of the
static calculations as part of the PV substructure dimensioning. A structural engineer must inspect and
approve of the increased and rearranged loads caused by the PV plant on site.
