CLC/TC 205A Mains communicating systems
European Norm
33.040.30 Switching and signalling systems
This standard applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network or within installations in consumers’ premises. It specifies the frequency bands allocated to the different applications, limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement. It does not specify the modulation methods, the coding methods or functional features (except those for the prevention of mutual interference). Environmental requirements and tests are not included. NOTE 1 Compliance with this standard does not imply permission to establish communication with locations outside the consumer’s installation or with other consumers through the public electricity distribution network where this would not otherwise be allowed. The object of the standard is to limit mutual influence between transmission equipment in electrical installations and between such equipment and other equipment. In addition this standard is intended to limit interference caused by signal transmission equipment to sensitive electronic equipment. However, complete freedom from such interference cannot be assured. NOTE 2 Designers should consider signalling systems in conformance with this standard when determining immunity for electrical equipment.
