Colour and marking identification of up to 400 VDC power distribution for information and communication technology systems
ITU-T L.1203 (02/2016)
Year: 2016
Abstract: This Recommendation ITU-T L.1203 defines the requirements and guidelines for DC power distribution identification by colour and marking in Telecom/ICT installations (wire, cables, electric distribution boards, interconnections, etc…). It avoids confusion and errors between the different AC and DC power interfaces and distributions used in buildings and inside Telecom/ICT systems, as 400VDC power feeding interfaces standardized in [ITU-T L.1200] is used more, increasing power density of ICT equipment, energy efficiency, simplified reliable power feeding architecture, costs optimisation, etc. Recommendation ITU-T L.1203 assists the progressive introduction of up to 400VDC installations in cohabitation with the existing -48V and AC distribution.
