This European Standard was approved by CENELEC on 2002-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 22H/22/FDIS, future edition 1 of IEC 62040-1-1, prepared by SC 22H,
Uninterruptible power systems (UPS), of IEC TC 22, Power electronic systems and equipment, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62040-1-1 on
2002-11-01.
This European Standard supersedes EN 50091-1-1:1996.

The following dates were fixed:

– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2003-08-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-11-01

Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes L, M, N and ZA are normative and annexes H and X are informative.
Annex ZA has been added by CENELEC.

In this standard, the following print types are used:
- Requirements proper and normative annexes: in roman type;
- Compliance statements and test specifications: in italic type;
- Notes and other informative matter: in smaller roman type;
- Normative conditions within tables: in smaller roman type;
- Terms that are defined in clause 3: bold.
