IMPORTANT WARNINGS
Solar modules generate electricity as soon as they are exposed to light, so they are always
live. Although the fully insulated plug contacts provide protection against accidental contact,
you must pay attention to the following when handling the solar modules:
Do not insert electrically conductive parts into the plugs and sockets.
Do not mount solar modules and cables with wet plugs and sockets.
Perform all work on the lines with extreme caution.
Do not carry out any electrical installation work in damp conditions.
Even with low illumination, very high direct voltages are generated at the series connection
of solar modules, which are life-threatening if touched. Pay particular attention to the
possibility of secondary damage from electric shock. DIN VDE 0100-540 Selection
and erection of electrical equipment -Earthing arrangements and protective conductors.
High contact voltages can occur in the inverter even when it is disconnected:
Be especially careful when working on the inverter and the cables.
After switching off the inverter and carrying out other work, it is essential to observe
the time intervals specified by the manufacturer to allow the high-voltage components
to discharge.
Please also observe the installation instructions provided by the inverter manufacturer.
Opening a closed string (e.g. when disconnecting the DC line from the inverter under load)
can cause a lethal electric arc:
Never disconnect the solar generator from the inverter while it is connected to the grid.
NOTES ON RACK INSTALLATION
For installation in the roof area, you must observe the currently valid rules of construction
engineering, in particular the requirements formulated in the DIN standards and in the
regulations of the German roofing trade ("Regelwerk des Deutschen Dachdeckerhandwerks").
Check that all screw connections are tight.
Observe the specified torques.
Irrespective of verifiable statics, you must ensure in advance of each installation that the
product meets the static requirements on site in accordance with DIN EN 1991.
DIN standard EN 1991 "Actions on structures" –and all related national application documents
Part 1-1: Weights, dead weight and payloads in building construction
Part 1-3: Snow loads
Part 1-4: Wind loads
DIN standard EN 1990: "Basis of structural design" –and all related national application
documents.
The design of the assembly rack is carried out in accordance with DIN EN 1993 "Design of
steel structures" and DIN EN 1999 "Design of aluminium structures«.
Ensure that the substructure is suitable in terms of load-bearing capacity (dimensioning, state of
preservation, suitable material characteristics), load-bearing structure and other layers affected
by this (e.g. insulation layer).
Make sure that the drainage of rainwater is not hindered.
Take into account aspects of building physics (e.g. possible condensation when penetrating
insulation layers).
STANDARDS AND GUIDELINES
All listed standards and guidelines have been issued and are applicable in Germany. They must
be taken into account by referring to the latest valid version as amended. Outside Germany,
please also observe the relevant national standards and guidelines.
