This VDE application rule contains supplementary recommendations to mitigate the likelihood of electric
shock to emergency personnel in case of fire (or similar) resulting from the fact that PV modules can produce
voltage when exposed to light, even if the AC side is disconnected.
•
In order to inform firefighters that there is a PV system on the roof of the house, for example, it is
recommended that a photovoltaic system fire sign be placed on the side of the building where the
main access road is located. By having a PV system sign immediately visible, firefighters will have
advance notice of potential hazards that may be posed by the PV system in the event of a fire.
•
Create sufficiently detailed documentation of the PV system ,to support a hazard-free execution of the
extinguishing process. Ensure that the system documentation is accessible to the fire department in
the event of a fire.
Safety distances for an extinguishing process in PV systems (according to DIN VDE 0132)

•
Do not install modules near open fire or flammable and explosive gases/substances.
•
Only use plugs and sockets of the same manufacturer and type.
•
Only use devices, plugs, cables and support frames that are suitable for use in a solar power system.
•
Use temperature and UV resistant materials.
Mechanical installation
General notes
Always use constructions and materials that have been specially developed and certified for the installation of
photovoltaic modules. Always follow the instructions and safety precautions of the mounting system
manufacturer.
•
Do not remove any components, such as plugs or cables, or attached nameplates.
•
Do not apply paint or glue to the top of the module.
•
Do not concentrate artificial sunlight on the solar module.
•
Do not disassemble, drill or modify the frame or other parts of the PV module.
Safety instructions
•
Do not install in high winds and prevent objects from falling from the roof.
•
Secure the work area so that no one on or under the roof can be injured.
•
When installing a module on a roof or building, make sure it is securely fastened.
•
Avoid subjecting the frame to lateral tension and compression forces, as this could damage the glass.
•
Do not bend the module frame.
•
Do not damage the frame.
•
Do not place the module down hard.
•
Do not drop any objects on the module.
•
Do not place heavy objects on the module.
