1. General Information
•The soil conditions for the structures should be leveled and load-bearing.
•The electrical connection may only be carried out by a qualified electrician.
•The completed photovoltaic project should be completely surrounded by a fence
to protect it from unauthorized access or damage by wild animals.
•All packaging material must be disposed properly in accordance with legal and
technical regulations. See EN 378.
•The mounting systems from Oberhauser serve exclusively as substructure for
installing photovoltaic modules and may only be used in accordance with their
structural analysis.
•The photovoltaic modules may only be installed in accordance with the
manufacturer's instructions.

1.3 Tightening torques for screws
Hexagon head screw DIN933 M12x40 (ram profile (A) - rafter profile (B)) 100 Nm
Hexagon head screw DIN EN 14399/4 M12x40 (HV) 130 Nm
Hexagon head screw DIN933 M12x40 (rafter profile (B) - purlins (C)) 60 Nm
Screws for module clamps 8 - 10 Nm
After assembly, a random check of the tightening torque, min. 5 % of all screw connections, is
recommended. The inspection should be repeated annually as part of the maintenance work.
2. The Assembly
A proven method is the foundation by means of ram profiles consisting of galvanized steel. The static
requirements at the site and the results of the soil investigation are decisive for the length of the
piles.
These are rammed into the ground by pile-driving machines, whereby optimum alignment in all
directions is possible.
Step 1: Measuring of the ram points and material distribution
Red marks:
These marks are measured in advance by the surveyor and permanently marked. The surveyor is
commissioned by the client and should start surveying at the earliest one week before the start of
construction and have completed the work by the day of the start of construction at the latest.
Black marks:
These marks are measured by the installation team. This is usually done by laying out a long
measuring tape (50 - 100 m) and then marking the ram points (black marks) on the measuring tape.
The distances depend on the pile-driving plan and the measuring charts which you receive from
Oberhauser.
The material (piles) is then distributed in the field to make assembly times more efficient.
