Electromagnetic compatibility (EMC). Limits - Guide to signalling on low-voltage electrical installations. Emission levels, frequency bands and electromagnetic disturbance levels1 Scope This section of IEC 610003 applies to electrical equipment using signals in the frequency range from 3 kHz up to 525 kHz to transmit information on low voltage electrical installations, either on the public supply system or within customers premises. It specifies frequency bands allocated to different applications (where appropriate), limits for the terminal output voltage in the operating band and limits for conducted and radiated
