The solar modules are designated for use in gridcoupled
solar generators. When used for another purpose, the
respective deviating technical particularities must be
observed. The solar modules may only be installed by
qualified specialized companies. In this context, the
norms and regulations relevant to PV systems, such as
VDE provisions, DIN norms, VDEW guidelines, the TAB of
the competent system operators along with the rules set
forth by the Employers‘ Liability Insurance Associations
on accident prevention.
Particular reference is made once again to the following
items:
Prior to the installation, the connector socket, cables
and plug connectors are to be checked for damage
and dirt.
Do not install any damaged PV modules or any PV
modules with dirty plug connectors.
The solar modules (particularly the plug connectors
and tools) must be dry during the installation.
For the switching of module strings, only suitable
(UV- and ozone-resistant) cables are to be used for
outside installation.
The cables must have a minimum cross-section of
4 mm², and the insulation must be approved for the
maximum system atrest voltage.
The cables are to be protected from damage by using
e. g. a suitable fastener via cable clamps.
The connector socket with cables connected at the
plant may not be opened.
The connector socket, the cable and the connector
plug may not be cleaned or otherwise moistened
with substances containing oil, grease or alcohol.
The solar plugs installed by the plant may not be
removed.
In the course of the installation, one must ensure the
tensile relief of the module connector cables.

Important Notice!

The connector cables are equipped with a high-quali-
ty plug-connector system for photovoltaics. The plugs
are marked with the respective polarity, or the cables
are designed in red for “plus” and blue for “minus”;
see Table 2 and the data sheet.
When connecting the plug connectors and the mo-
dules (and when connecting the solar modules to the
frequency inverter), always ensure that the polarity is
correct. Reverse polarity leads to the destruction of
important technical structural components such as
frequency inverters, safety diodes or similar compon-
ents.
The connector cables are to be laid so as to ensure
that the minimum bend radius of 60 mm is not un-
dershot.
In order to avoid the hazard of electric shocks, all
frames of the solar modules as well as the support
structure for potential equalization must be con-
nected to the grounding so as to ensure good con-
ductivity. We recommend grounding outside the
building. In this process, observe the statutory regu-
lations for your region, along with the recommenda-
tions issued by the frequency-inverter manufacturers
and the insurance company.
Never plug in or unplug the plug contacts when under
load current!
