Signalling on low-voltage electrical installations in the frequency range 3kHz to 148.5 kHz. Part 1: General requirements, frequency bands and electromagnetic disturbances
This Standard applies co electrical equtpment using signals in che frequency rang. 3 kHz te 148,5 kHz to tranamit Information on low voltage electrical systems, either on che public supply system or wichin installations in consumars' premises.
It specifies the frequency bands allocated to che different applicattons, limits for tha terminal output voltage in che operacir.g band and limics for conducced and radiated disturbance. Ie also gives the mechods of measurement.
It does not specify che signal modulation methods nor the coding methods nor funccional features (except those for che prevencion of mutual interference).
Environmental requirements and tests ar* not includad.
Note: In most countries tha transmission of Information is subject co regulation. Complianca with this Standard does not imply permission to establish communication with locations outsida che consumar's installation or with other consumars chrough che public supply system whara this would not otherwise be allowed.
