4 General requirements
Replace the eighth paragraph with the following:
Assemblies for EV supply equipment shall comply with IEC TS 61439-7 with the exceptions or
additions as indicated in Clause 12.

12.9 Damp heat functional test
Replace the second paragraph with the following:
Conditioning:
− for indoor units, 6 cycles of 24 h each to a damp heat cycling test according to
IEC 60068-2-30 (Test Db) at (40 ± 3) °C and relative humidity of 95 %;
− for outdoor units, two 5-day periods, with each period consisting of 5 cycles of 24 h each
to a damp heat cycling test according to IEC 60068-2-30 (Test Db) at (40 ± 3) °C and
relative humidity of 95 %.
12.11 Mechanical strength
Replace, in the second paragraph, the first dashed item with the following:
– the IP degree according to 12.4 is not impaired;

Table A.6 – List of sequences
Replace, in sequence 2.1 Unplug at state Bx, in the “Conditions” column, the text for (19) and
(20) with the following:
(19) EV connected to the EV supply equipment in state B
(20) Plug disconnected from the EV supply equipment or vehicle connector disconnected from
the vehicle inlet
The EV supply equipment shall allow removal of the plug automatically, at a maximum of 5 s,
when entering state A (case A or B) unless the locking was initiated through user interaction
(e.g. authorization). Then unlatching / unlocking can be done only by using the adequate user
interaction or both.
In case A, EV with attached cable, a switch may be added on the control pilot circuit, on the EV
side (cable, plug, vehicle), to simulate the EV disconnection (state A).

A.4.9 Test of short-circuit values of the voltage
Replace the second paragraph with the following:

been attained for at least 5 s, a supplementary resistance of 80 Ω is switched to connect
between the control pilot conductor and the protective conductor.

Figure A.8 – Example of a test circuit (EV simulator)
In the figure, replace the resistor values for R13, R31 and R32 as follows:

Replace, in NOTE 2, the description of resistance R3 with the following:
The resistance R3 in Figure A.1 is simulated by SW3 and resistors R30 (1 870 Ω), R31 (870 Ω) and R32 (1 870 Ω)
as follows:
– Position 2: R3 has its nominal value;

C.2 Circuits diagrams for Mode 1, Mode 2 and Mode 3, using a basic single
phase vehicle coupler
Delete Figure C.3.
Replace the first paragraph with the following:
Figures C.1, C.2 and C.4 below show the application of a single phase basic interface fitted
with a switch on the proximity circuits.
Replace the fourth paragraph with the following:
Figures C.1, C.2 and C.4 can also be realized with a connector that lacks a switch provided the
switch S3 is not required.
Replace the ninth paragraph with the following:
Both Mode 2 diagram shown in Figure C.2 and Mode 3 diagram shown in Figure C.4 have been
drawn with a hard wired control pilot functions as described in Annex A. The basic functions
described in Annex A are represented by R1, R2, R3, D and S2 (see Figure A.1). The values
indicated in Annex A should be used (see Table A.3).

D.10.6 Test of short circuit between the control pilot conductor and the protective
conductor
Replace the third paragraph with the following:
A supplementary resistance of 80 Ω is switched to connect the control pilot conduct
