Uninterruptible power systems (UPS) - Part 2: Electromagnetic compatibility (EMC) requirements
IEC 62040-2:2016 is a type test product standard for electromagnetic compatibility (EMC) and applies to movable, stationary, fixed or built-in, pluggable and permanently connected UPS for use in low-voltage distribution systems with an environment being either residential, commercial, light industrial or industrial, which deliver output voltage with port voltages not exceeding 1 500 V DC or 1 000 V AC and which include an energy storage device. This edition includes the following significant technical changes with respect to the previous edition:
a) the inclusion of network port limits in Table 1, Table 2 and Annex C for the sake of consistency with other standards;
b) a change of quasi-peak limit for category C3 UPS in Table 2 for the sake of consistency with other standards;
c) a clarification in Table 4 about the performance criteria for immunity tests;
d) a revision of some test configurations in Annex A.
The contents of the Interpretation sheet 1 of June 2018 have been included in this copy.
Alimentations sans interruption (ASI) - Partie 2: Exigences pour la compatibilité électromagnétique (CEM)
L'IEC 62040-2:2016 est une norme de produit pour les essais de type en matière de compatibilité électromagnétique (CEM). Elle s'applique aux ASI mobiles, stationnaires, installées à poste fixe ou intégrées, enfichables et connectées en permanence, destinées à une utilisation dans les réseaux de distribution basse tension d'un environnement résidentiel, commercial, d'industrie légère ou industriel, qui fournissent une tension de sortie ne dépassant pas 1 000 V en courant alternatif ou 1 500 V en courant continu au niveau de l'accès, et qui incluent un dispositif de stockage d'énergie. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) l'intégration des limites pour les accès réseau de télécommunication dans le Tableau 1, le Tableau 2 et l'Annexe C, à des fins de cohérence avec d'autres normes;
b) une modification des limites quasi-crête pour les ASI de catégorie C3 dans le Tableau 2, à des fins de cohérence avec d'autres normes;
c) une clarification des critères de performance destinés aux essais d'immunité dans le Tableau 4;
d) une révision de certaines configurations d'essai dans l'Annexe A.

Interpretation of 5.3.2.4, Limits at the network ports
Introduction
Sub-clause 5.3.2.4 states that the network port limits applicable to UPS of category C1, C2
and C3 are located in Table 1, Table 2 and Annex C.
It was not clear whether 5.3.2.4 applies to network ports that originate and terminate within
the enclosure port of the UPS (i.e. to network ports connected exclusively to circuits or
devices forming an integral part of the UPS).
Interpretation
The network port limits in Table 1, Table 2 and Annex C apply only to network ports for
which connection to circuits or devices external to the enclosure port of the UPS is allowed.
This includes, without limitation, connection to PSTN, ISDN, xDSL and Ethernet networks.
The limits in Table 1, Table 2 and Annex C do not apply to network ports that originate and
terminate within the enclosure port of the UPS (i.e. to network ports connected exclusively
to circuits or devices forming an integral part of the UPS).
