This European Standard was approved by CENELEC on 2006-11-01. 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, Cyprus, the Czech

Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword

The text of document 17A/759/FDIS, future edition 1 of IEC 62271-109, prepared by SC 17A,

High-voltage switchgear and controlgear, of IEC TC 17, Switchgear and controlgear, was submitted to the

IEC-CENELEC parallel vote and was approved by CENELEC as EN 62271-109 on 2006-11-01.

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) 2007-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-11-01

This standard should be read in conjunction with EN 62271-100:2001 and EN 60694:1996, to which it

refers and which is applicable, unless otherwise specified. In order to simplify the indication of

corresponding requirements, the same numbering of clauses and subclauses is used as in EN 60694.

Amendments to these clauses and subclauses are given under the same numbering, whilst additional

subclauses are numbered from 101.
Annex ZA has been added by CENELEC.
