Uninterruptible power systems (UPS) - Part 2: Electromagnetic compatibility (EMC) requirements

Is intended as a product standard allowing the EMC conformity assessment of products of categories C1, C2 and C3 as defined in this part of EN 62040, before placing them on the market.The requirements have been selected so as to ensure an adequate level of electromagnetic compatibility (EMC) for UPS at public and industrial locations.

Unterbrechungsfreie Stromversorgungssysteme (USV) - Teil 2: Anforderungen an die elektromagnetische Verträglichkeit (EMV)

Alimentations sans interruption (ASI) - Partie 2: Exigences pour la compatibilité électromagnétique (CEM)

Est une norme de produit permettant l'évaluation de conformité CEM des produits de catégories C1, C2 et C3 définis dans la présente partie de la EN 62040, avant leur commercialisation.Les exigences ont été sélectionnées afin d'assurer un niveau de compatibilité électromagnétique (CEM) adéquat pour les ASI destinées à un environnement domestique ou industriel.

Sistemi z neprekinjenim napajanjem - 2. del: Zahteve za elektromagnetno združljivost (EMC) (IEC 62040-2:2016)

Namenjen je kot standard za izdelke, ki omogoča ocenjevanje skladnosti elektromagnetne združljivosti (EMC) izdelkov kategorij C1, C2 in C3, kot je opredeljeno v tem delu standarda EN 62040, pred dajanjem na trg. Zahteve so bile izbrane tako, da zagotavljajo ustrezno raven elektromagnetne združljivosti za sisteme z neprekinjenim napajanjem na javnih in industrijskih lokacijah.

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).

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
