Overvoltage category III (AC output): The device is suitable for permanent connection in the grid distribution behind the meter and the line protection fuse. If the connection cable travels outdoors over long distances, overvoltage protection devices may be necessary.
Degree of contamination 4: Contamination results in continuous conductivity, e.g. due to conductive dust, rain or snow; indoors or outdoors.
Automatic disconnection device in accordance with VDE V 0126-1-1, for Austria: The inverter is equipped "with automatic disconnection device in accordance with ÖVE/ÖNORM E 8001-4-712".
Noise emission: Measured under rated output at an ambient temperature of 23 °C. If a string connection is unfavourable or there is a higher ambient temperature, the noise emission may be up to 48 dB(A).
