Installation location
The following information is intended to serve as a guide for
the planner. it cannot cover all of the technical possibilities and
mounting options. Rather, it sets out the minimum requirements
for mounting the modules.
comply with the following notes on the installation location:
The modules are tested in accordance with iEc 61646, 61730
and uL 1703 for safe use in a moderate climate.
Modules are not explosion-proof devices.
¼
Donotoperatethemodulesnearhighlyflammablegasesand
vapors (e.g. gas containers, petrol stations).
¼
Do not subject the modules to severe chemical stresses.
¼
The junction box only has splash protection (iP 67).
¼
Do not install the modules in closed rooms.
¼
Do not install modules at locations where standing water can
collect.
¼
The modules are not suitable for mobile use.
¼
Roof-integrated installation (BiPv) is not permitted.
requirements on the mounting frame
The mounting frame:
fulfilstherequiredstatic.
corresponds to the local snow and wind load requirements.
is anchored stably in the ground, on the roof or on the façade.
transfers forces occurring on the module to the substructure.
ensuressufficientbackventilationofthemodule.
in combination with a suitable clamp, enables stress-free,
temperature-dependent expansion and contraction of the
module and the substructure.
has electrochemical properties, which prevent corrosion
between different metals.
creates a plane mounting surface to which the modules can be
fixed,withamaximumdeviationof3mm/minalldirections
¼
The clamps and rail system must be compatible.
¼
Ensure that no mechanical stresses (e.g. due to vibrations,
rotations or expansions) are generated on the module.

installation with the junction box in the top section of the
module. The connection cables hang down.
The optimal inclination angle of the module depends on the
latitude.
¼
Do not seal up the drainage openings.
¼
Ensure that rainwater and snowmelt can run off freely.
¼
We recommend a minimum inclination of 3°
¼
An angle of 20° promotes self-cleaning in the rain
