Pertains to plugs and fixed socketoutlets 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.

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 socketoutlets 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 6^th paragraph, the second dash with:

• an overcurrent protection (of 17,6 A or less for each socket-outlet or multiple socketoutlet),
