2.4 Grounding
2.5 Proper Operation
If the modules are installed according to the instructions above, the system components must result in a
proper operation of the modules. If the modules are not operated properly, the warranty can become void or
at least significantly limited.
2.6 Other Specifications
 The modules must be installed in an environment in which it is ensured that the operating
temperature range will not exceed or fall below -40°C to +85°C. Sufficient air circulation behind the
modules should particularly be ensured in hot environments.
 Modules must not be operated under short-circuit conditions.
 All shading of the module array is to be avoided.
 The modules must not be immersed in water.
 Do not artificially bundle sunlight by means of mirrors, lenses or other devices onto the module.
 Earthing of the modules shall only be carried out at the locations on the frame profile specified for
this purpose via an earth cable that is connected electrically conductive with the frame.
 If the modules are assembled near the sea, a minimum distance of 200 m to the coastline must be
ensured.
Proper earthing is the responsibility of the company
carrying out the installation and is to be attached to
the module frame. If a lightning protection system is
already present or intended to be installed on the
building, the PV system is to be integrated into the
protection concept against direct lightning strike. It is
recommended to provide potential compensation on
the frame when using an inverter without a
transformer. Earth is indicated on the module frame.
The earthing holes must remain unobstructed and
must not be covered.
The recommended cross-section of the cable is 4
mm². Only certified cables must be used for earthing
and module connection. The minimum bending radius
is 5x the cable diameter.
Country-specific standards are to be adhered to.
The connection of the inverter to the module arrays
must be carried out properly and to professional
standards.
