Introduction The present document has been developed to assist the ICT industry in their development and wider use of DC powering solutions above the DC voltage range mainly u
22、sed until now for Telecommunication networks equipment (-48 V ETSI EN 300 132-2 7). The present document has been jointly developed by ETSI TC EE and ITU-T Study Group 5 in order to ensure an equivalent technical content. It is published respectively by ITU as Recommendation ITU-T L.1203 1 and ETSI
23、Standard ETSI ES 203 408. DC has been the main source of power of Telecommunication industry since the very beginning as it is efficient, reliable and easily scalable. This solution is a well proven arrangement that has been used for a century in almost all of the sites in cohabitation with AC for s
24、ervers and other buildings services (lighting, facility plugs, lifts, etc.). It is recognized that DC has many potential applications further to those for ICT and that such applications could benefit from the standards defined in ITU/ETSI. It is also recognized that further standardization activitie
25、s on LVDC is now starting in other standardization organizations such as IEC. Thus ITU-T/ETSI will pursue cooperation with such organizations to reach maximum international alignment. ETSI and ITU-T have standardized the widespread DC power interface at inputs of Telecom/ICT equipment used in Teleco
26、m networks, Data centers, and customer sites. The legacy interface for billions of equipment is the SELV voltage range so called -48V, where the plus pole is grounded as defined for example for interface “A“ in ETSI EN 300 132-2 7. Other complementary ETSI standards define a whole DC distribution in
27、cluding earthing and bonding such as ETSI EN 300 253 9. Higher voltages than 48 V are already widely used in Telecom networks for remote powering of signal repeaters on copper or optical Telecom transmission lines, with a usual operation in symmetrical voltage up to +/- 200 V in RFT-C or RFT-V telec
28、om remote power feeding standardized in ETSI EN 302 099 i.1. ETSI ETSI ES 203 408 V1.1.1 (2016-12) 6 Higher power density of ICT equipment and overall site power in MW for Data centers, have led to the use of higher voltage firstly in AC single or 3 phases up to 400VAC at the input of servers. The n
29、eed for resilience, energy efficiency and cost optimization has pushed the introduction of the up to 400VDC power feeding interface standardized in ETSI EN 300 132-3-1 8 and in Recommendation ITU-T L.1200 2. This is now available on many servers and network equipment. As there is a progressive intro
30、duction of the new DC power interface in cohabitation with existing -48 V and AC distribution, a new standard ETSI EN 301 605 10 has been introduced to ensure safety and proper operation especially in mass bonding of EMC sensitive equipment and correct earthing connection to the building structure e
31、arthing network. It appears that there is also a strong need for Telecom/Data centers operators, equipment manufacturers or installers and end customers to clarify the colour and marking of cables in their installations. This would avoid confusion and errors between the different AC and DC power int
32、erfaces and distributions used in the building and inside ICT systems. Considering the user side, and very long background experience in use of DC of the Telecom sector, the present document makes Recommendations directly contributing to safety principles laid down in IEC Guide 104 i.9 and ISO/IEC G
33、uide 51 i.10. It accelerates and encourages the preparation of international standards of cable identification intended for use by manufacturers, users or certification bodies. The present document makes reference to existing IEC standards such as IEC 60445 3 and IEC 60050-195 i.2. For useful inform
34、ation, colours of cables inside equipment are considered in annex A as DC is already widely used, e.g. all the electronic being working only in DC, car and trucks electric circuit being in DC, solar PV power plants, etc. ETSI ETSI ES 203 408 V1.1.1 (2016-12) 7 1 Scope The scope of the present docume
35、nt is to define common practice for identification of cabling or parts of the DC electric distribution for the Telecom sites (buildings/rooms) feeding ICT and facilities equipment (power plant, cooling, building access systems, monitoring, etc.). This applies to 400VDC cabling for Telecom, ICT equip
36、ment and environment equipment using interface defined in ETSI EN 300 132-3-1 8 or Recommendation ITU-T L.1200 2 and avoids confusion between the DC colour and marking of up to 400VDC distribution and the other power interfaces identification: -48VDC distribution for A interface, AC and uninterrupte
37、d AC given by inverters or UPS used in the building. The Recommendation defines: requirements for the colour and identification of separate wires used in DC distribution systems and installations, and as much as possible inside equipment between A or P interface and end use; marking and identificati
38、on of DC multiwire cables, connectors and any associated equipment for DC power distribution; marking identification for sui-distribution boards and interconnection boxes. For DC wires in multiwire cables Recommendations are given for harmonization with separate wire requirements. Recommendations ar
39、e given on other distribution items (wires, cables and interconnection items) including the functional earthing and bonding arrangement for distribution outside and inside equipment to avoid any confusion with DC distribution identification of the present document. 2 References 2.1 Normative referen
