Unified Comfort Panels
144 Operating Instructions, 03/2020, A5E46641217-AA
8.3 Electromagnetic compatibility
The device fulfills, amongst others, the requirements of the EMC directive applicable to the
European domestic market.
Installing the device according to EMC directive
EMC-compliant mounting of the device and the use of interference-proof cables provide the
basis for interference-free operation.
