1 Scope
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),
