with TC 13 products.”
Renumber the original NOTE as “NOTE 1”.
In 9.3.2.2, add the following note to Table 17, “Voltage dips, short interruptions and voltage variations on
DC input power port immunity tests”:
“
NOTE ΔU specifies the percentage voltage reduction in Table 17. The basic standard IEC 61000-4-11 specifies the
residual voltage instead. Also, tests were modified partly compared to the basic standard based on long field experience
with TC13 products.”
5 Modification to Annex ZA, “Normative references to international publications
with their corresponding European publications”
Replace the Annex ZA with the following:
“Annex ZA
(normative)

Normative references to international publications with their corresponding
European publications
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
NOTE 1 When an International Publication has been modified by common modifications, indicated by (mod), the
relevant EN/HD applies.
NOTE 2 Up-to-date information on the latest versions of the European Standards listed in this annex is available here:
