Select STSI/STSR stud positions based on roof structure, wind and snow load calculations and panel layout required.
In application with STSI screws is necessary a pre-drill in steel structure of 6.8 mm with a steel thickness of 2-4 mm.
In application with STSR screws in wood beam probably is not necessary a pre-drill.
Screwing until complete penetration of the threaded part and apply the SSP plates or brackets MW always directed toward the top of the roof.
Not following the instruction above may reduce the load capacity of the system.
Assemble profiles fischer Solar connecting them to the brackets with Hex head screws and nuts MU already included in the package.
Do not tighten the screws until completion of the row of profiles.
The maximum allowable cantilever of the profile from the support is equal to 1/3 of the supports spacing.
If necessary, connect more profiles with a pair of joints CPN AL. Insert the joints into the sides of the profile. The small protrusion indicates a full assembly. The next profile can then be pushed in place.
After placing all profiles tighten the connecting screws to the triangular frame with a torque of 10 Nm.
To avoid problems related to thermal expansion we recommend a maximum length of 15 m per row.
If the connection is on the side spans, the joints CPN AL have to be fixed with self drilling screws.
Do not join profiles in the projecting section.
Put the final and middle clamps on the profiles with a gap equal to the width of the panel.
To avoid the panels sliding during installation, use the FV-PS supports in the top profile.
Place the first photovoltaic panel and tighten the final clamps to fasten the panel with a torque of 10 Nm.
Place side by side the subsequent PV panels to completion of the row and fasten progressively with final and middle clamps.
