Central Secretariat: rue de Stassart 35, Foreword
The text of document 22H/74A/FDIS, future edition 2 of IEC 62040-2, prepared by SC 22H, Uninterruptible Power Systems (UPS), of IECTC22, Power electronic systems and equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62040-2 on 2005-10-01.
This European Standard supersedes EN 50091-2:1995 + corrigendum January 1998.
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) 2006-10-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-10-01
This European Standard was prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and supports the essential requirements of Directive 89/336/EEC (see Annex ZZ).
Annexes ZA and ZZ have been added by CENELEC.
The contents of the corrigendum of November 2006 have been included in this copy.
Endorsement notice
The text of the International Standard IEC 62040-2:2005 was approved by CENELEC as a European Standard without any modification.
