Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).
