Uninterruptible Power Systems (UPS) - Part 1: General and safety requirements for UPS (IEC 62040-1:2008 (EQV) + corrigendum Aug. 2008)
This part of IEC 62040 applies to uninterruptible power systems (UPS) with an electrical energy storage device in the d.c. link. It is used with IEC 60950-1, which is referred to in this standard as "RD" (reference document). NOTE UPS applications generally make use of a chemical battery as the energy storage device. Alternative devices may be suitable, and as such, where “battery” appears in the text of this standard, where applicable, this may be understood as “energy storage device”. When a clause is referred to by the phrase "The definitions or the provisions of item/RD apply", this phrase is intended to mean that the definitions or provisions in that clause of IEC 60950-1 apply, except any which are clearly inapplicable to uninterruptible power systems. National requirements additional to those in IEC 60950-1 apply and are found as notes under relevant clauses of the RD. The primary function of the UPS covered by this standard is to ensure continuity of an alternating power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. This standard is applicable to UPS which are movable, stationary, fixed or for building-in, for use in low-voltage distribution systems and intended to be installed in any operator accessible area or in restricted access locations as applicable. It specifies requirements to ensure safety for the operator and layman who may come into contact with the equipment and, where specifically stated, for the service person. This standard is intended to ensure the safety of installed UPS, both as a single UPS unit or as a system of interconnected UPS units, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer. This standard does not cover UPS based on rotating machines. Electromagnetic compatibility (EMC) requirements and definitions are given in IEC 62040-2.

Alimentations sans interruption (ASI) - Part 1 : Exigences générales et règles de sécurité pour les ASI (CEI 62040-1-1:2008 (EQV) + corrigendum Aug.2008)
La CEI 62040-1 2008 s'applique aux alimentations sans interruption (ASI) possédant un dispositif d'accumulation de l'énergie sur la liaison à courant continu. Elle est utilisée conjointement avec la CEI 60950-1, qui est référencée 'RD' (document de référence) dans la présente norme. Elle s'applique aux ASI mobiles, fixes ou installées, pour utilisation sur systèmes de distribution basse tension et destinées à être installées dans toute zone accessible aux opérateurs ou dans des emplacements à accès restreint, selon le cas. Elle spécifie des exigences destinées à assurer la sécurité des opérateurs ou des ouvriers qui peuvent se trouver en contact avec le matériel et, lorsque cela est spécifiquement précisé, du personnel de maintenance. Elle annule et remplace la première édition de la CEI 62040-1-1, publiée en 2004 et la CEI 62040-1-2, publiée en 2004 et constitue une révision technique. Cette norme reprend toutes les exigences des précédentes CEI 62040-1-1 et CEI 62040-1-2, avec en plus les suivantes: - mise à jour des références normatives incluant la CEI 60950-1 comme Document de Référence (RD); - harmonisation et alignement des meilleures pratiques actuelles reconnues mondialement; - accroissement de la protection contre les retours de tension, définition du défaut d'isolement, révision des tableaux d'échauffement et de la concentration en hydrogène dans les compartiments de batterie. Le contenu du corrigendum de septembre 2008 a été pris en considération dans cet exemplaire.
Sistemi z neprekinjanim napajanjem (UPS) - 1. del: Splošne in varnostne zahteve za UPS (IEC 62040-1:2008 (EQV) + corrigendum Aug. 2008)) (vsebuje popravek AC:2009)
Ta del IEC 62040 se nanaša na sisteme neprekinjenega napajanja (UPS) z napravo za shranjevanje električne energije v enosmerni povezavi. Uporablja se z IEC 60950-1, ki je v tem standardu označen z »RD« (referenčni dokument). OPOMBA Aplikacije UPS za shranjevanje energije običajno uporabljajo kemične baterije. Uporabljajo se lahko tudi druge naprave. Ko se torej v besedilu tega standarda pojavi »baterija«, se ponekod to lahko razume kot »naprava za shranjevanje energije«. Ko smo na točko usmerjeni s frazo »Upoštevajo se definicije ali določbe elementa/RD«, ta fraza pomeni, da se upoštevajo definicije ali določbe v tej točki IEC 60950-1, razen takšnih, ki očitno ne veljajo za sisteme neprekinjenega napajanja. Upoštevajo se nacionalne zahteve poleg IEC 60950-1, najdete pa jih pod opombami pod ustreznimi točkami RD. Primarna funkcija sistemov neprekinjenega napajanja v okviru tega standarda je zagotavljanje neprekinjenega vira izmeničnega napajanja. Sistem neprekinjenega napajanja se lahko uporablja tudi za izboljšanje kakovosti napajanja, tako da ga ohranja v okviru določenih karakteristik. Ta standard se nanaša na sisteme neprekinjenega napajanja, ki so premični, stacionarni, fiksni ali namenjeni vgradnji, za uporabo v nizkonapetostnih razdelilnih sistemih in namenjeni vgradnji na katero koli mesto, ki je dostopno operaterjem ali na ustrezne lokacije z omejenim dostopom. Določa zahteve za zagotavljanje varnosti operaterja in nestrokovnjakov, ki pridejo v stik z opremo, in (če je to izrecno omenjeno) serviserjev. Ta standard zagotavlja varnost vgrajenih sistemov neprekinjenega napajanja tako kot samostojna enota sistema neprekinjenega napajanja ali kot sistem medsebojno povezanih enot sistema neprekinjenega napajanja, v skladu s smernicami za vgradnjo, upravljanje in vzdrževanje sistema neprekinjenega napajanja, ki jih je določil proizvajalec. Ta standard ne zajema sistema neprekinjenega napajanja, ki temelji na vrtečih se napravah. Zahteve in definicije za elektromagnetno združljivost (EMC) so podane v IEC 62040-2.

UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 1: General and safety requirements for UPS
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62040-1 has been prepared by subcommittee 22H: Uninterruptible
power systems (UPS), of IEC technical committee 22: Power electronic systems and
equipment.
This standard cancels and replaces the first edition of IEC 62040-1-1, published in 2004 and

UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 1: General and safety requirements for UPS
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62040-1 has been prepared by subcommittee 22H: Uninterruptible
power systems (UPS), of IEC technical committee 22: Power electronic systems and
equipment.
This standard cancels and replaces the first edition of IEC 62040-1-1, published in 2004 and
IEC 62040-1-2, published in 2004 and constitutes a technical revision. This standard merges
all requirements of previous IEC 62040-1-1 and IEC 62040-1-2, with the addition of the
