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.

3. Theft protection
"Opportunity makes the thief!" In order to prevent this from happening, we will be pleased to supply
you with our safety balls or, optionally, shear nuts and/or safety screws on request.
Depending on the measures selected, theft is made more difficult or even prevented.
However, 100% theft protection is not possible, since any system can be "cracked" with the right tools
and in the required time.

15
4. Maintenance
Solar plants have to be maintained in regular intervals (at least once a year), to ensure an optimal
functioning and to meet the warranty requirements. At least once a year a visual inspection of the
profiles and fixing materials regarding damage or corrosion should be carried out and also a random
inspection of the connection points (screws, nuts) should be performed.
Especially after heavy weather occurrences like storms there should be additional inspections with
special emphasis on the exposed or outer areas of the project site where wind influences can cause
damages.
Damaged parts of the system have to be repaired or replaced. Loose screw connections have to be
tightened again using the torque information given in this manual (§1.3).
In case of polluted modules, we recommend to clean them for optimal performance. Module cleaning
should be performed by professional companies following the manufacturer’s instructions.
In case of major damages to the mounting system or to electrical parts, be advised to contact a
professional company. We point out that there are risks to health and life performing this work.
5. Surface treatment and corrosion
Oberhauser mounting systems are made of aluminium and/or galvanized steel. Depending on the
project location, the atmospheric conditions may vary.
The surface treatment also depends on the chemical characteristics of the soil. These must be provided
by the client by means of appropriate expert opinions when the contract is awarded.
The company Oberhauser Bau - Systeme GmbH certifies surface lifetime of 25 years within the scope
of and in accordance with all general terms and conditions of Oberhauser Bau - Systeme GmbH and
the following conditions.
1. The scope of the surface guarantee is limited, at our discretion, to the assumption of the costs
of repairing the defective profiles or the delivery of defect-free profiles at our expense to the
customer's place of business so that the customer can replace the defective profiles himself.
These must be profiles with the same or higher properties and of the same type.
2. The surface guarantee does not apply to transport damage or damage to the profiles during
installation. Profiles that are driven into the ground must be re-galvanised by the customer or
the appointed installation company. Post-zinc coating cannot be compared with a zinc coating
produced by the factory and must therefore be checked regularly and reworked if necessary.
3. The guarantee cannot be transferred to third parties
4. The surface guarantee is valid for 25 years for installations in areas with normal atmospheric
conditions with regard to corrosion (corrosion classes C1 to C3 according to EN ISO 12944-2).
Systems in more aggressive environments C4 - CX must be considered separately. Additional
corrosion protection is recommended in this case.
5. The surface guarantee does not apply to areas with heavily polluted air or closer than 2 km
from the sea coast and/or to areas where the installations frequently come into contact with
fresh or salt water.

16
6. The surface guarantee does not apply to installations exposed to any type of chemical that
may cause corrosion, such as smoke and rainwater containing carbon, deposits or particles of
heavy metals, alkaline products such as ash, cement or animal excrements, or to installations
located in the vicinity of a sewage treatment plant.
7. The visual appearance of the cutting edges and the discoloration of the zinc surface due to
water runoff from cutting edges or adjacent parts is not covered by the surface warranty.
8. The warranty does not apply to areas with high zinc abrasion (desert areas, areas with sandy
soils and strong winds).
9. The mounting system must be inspected annually by the customer or his vicarious agent. Any
damage detected must be repaired (scratches, dents, etc.) The entire system must be serviced
annually in accordance with Oberhauser's assembly instructions and the assembly and
maintenance instructions contained therein. The customer or his vicarious agent or his
representative is responsible for this.
10. All our warranty services are subject to full payment of the purchase price by the customer.
They exist within the granted period from the day of building approval, but at the latest from
the day of final invoicing.
11. These conditions are a complete part of the contract concluded between Oberhauser Bau-
Systeme GmbH and the customer.
6. Safety and liability
6.1 Electrical installation
Our assembly instructions do not provide any electrical installation instructions, but are exclusively
dedicated to the assembly of the substructure and the modules for a PV system.
Therefore we do not assume any liability for damages caused by the electrical system.
However, you should observe the following instructions:
●Installation and commissioning should be carried out by qualified electricians.
●Observe valid regulations and safety instructions.
●Do not carry out electrical installation in damp conditions.
●Even low lighting can lead to very high DC voltages at the connection of solar
modules and can therefore be life-threatening if touched!
6.2 Safety at work
The valid accident prevention regulations should be observed and followed for all types of work.
In addition, only tested power tools should be used and the danger area should be cordoned off.
In order to avoid injuries, sufficient personal protective equipment such as safety shoes, appropriate
work clothing, work gloves, safety goggles, helmet, etc. must be used.
Information can also be obtained from the building trade association.
