CAUTION! Incorrect orientation of the module may cause risk of fire hazard!
• The modules may be installed in landscape or portrait format.
• Framed modules must be installed with a minimum inclination angle according to chapter 4.
• Unframed modules can be installed roof-parallel with a minimum inclination angle of 3°.
• Install the module in such a way that the junction box is positioned in the upper area of
the module and the wires hang downwards (Figure 2).
• The modules must be mounted with a minumum distance of 10 mm from the next mod-
ule. Use all fastening points and avoid direct contact between the glass and metal (e.g.
mounting rails).
Unframed modules suitable are for use with wind and snow loads up to 2400 Pa.
Framed modules are suitable for use with wind and snow loads up to 5400 Pa.
Orient the module in such a way that rainwater and snowmelt can run off freely to avoid
standing water or puddling.
Ensure that the drainage openings of the frame are left open following installation to allow
water runoff. This prevents corrosion and frost damage.
Install the module to a mounting structure:
• that corresponds to the necessary statics and the local snow and wind loads.
• that is correctly fastened in the ground, on the roof or on the facade.
• that can transfer forces on the module to the assembly substructure.
• that ensures that no mechanical stresses (e.g. caused by vibrations, twisting or expansion)
are generated on the module.
• that ensures sufficient back ventilation of the module.
• that ensures long term stability.
• that will not give rise to galvanic corrosion in case of direct metal contact (i.e. grounding
lead, screws, washers, etc.)
• that allows for strain-free expansion and contraction due to natural ambient temperature
variations.
Clamps and rail system must be constructed as a coordinated unit.
Fasten the module according to the mounting variants. Adhere to the defined clamp areas in
Figure 2.
Ensure that the module cannot bend or twist more than 3 mm/m (without additional load
such as wind, snow, etc.). Observe the technical rules for point or linear supported glazing.
Position the module planar.
Depending upon the wind load and the angle of inclination, we also recommend attaching non-
slip safeguards to and spacers between the modules.
