Direct current (DC) plugs and socket-outlets for information and communication technology (ICT) equipment installed in data centres and telecom central offices - Part 2: Plug and socket-outlet system for 5,2 kW
This clause of Part 1 is applicable except as follows: Replacement: Replace the first paragraph with the following: This part of IEC 62735, which is a technical specification, applies to plugs and fixed socket- outlets for class I equipment with two active contacts plus an earthing contact, a rated power of 5,2 kW and a rated voltage range from 294 V to 400 V d.c. They are intended to power d.c. information and communication technology equipment only. The 2,6 kW system complying with Part 1 is safely compatible with the system complying with this part as it is possible to insert the 2,6 kW plug in the 5,2 kW socket-outlet but it is not possible to insert the 5,2 kW plug into the 2,6 kW socket-outlet. Replace the third paragraph with the following: The maximum current for the plug and the socket-outlet is 13 A when the voltage between live contacts is 400 V d.c; 17,6 A when the voltage between live contacts is 294 V d.c. and can rise up to 20 A when the voltage between live contacts decreases to 260 V d.c. for 10 min maximum. Replace, in the 6th paragraph, the second dash with; an overcurrent protection (of 17,6 A or less for each socket-outlet or multiple socket- outlet).
