This European Standard was approved by CENELEC on 2007-02-01. 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, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,

Foreword
The text of document 82/356/FDIS, future edition 1 of IEC 61730-1, prepared by IEC TC 82, Solar
photovoltaic energy systems, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, prepared by the Technical Committee CENELEC TC 82, Solar photovoltaic energy
systems, was submitted to the Unique Acceptance Procedure.
The combined texts were approved by CENELEC as EN 61730-1 on 2007-02-01.
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) 2008-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-02-01
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 61730-1:2004 was approved by CENELEC as a European
Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
General
Replace all references to "this part of IEC 61730" and "IEC 61730-2" by "this part of EN 61730" and
"EN 61730-2".
2 Normative references
Replace the entire clause by:
See Annex ZA.
3 Application classes
3.2 Class A: General access, hazardous voltage, hazardous power applications
Replace the text by:
Modules rated for use in this application class may be used in systems operating at greater than
120 V DC. Modules qualified for safety through this part of EN 61730 and EN 61730-2 within this
application class are considered to meet the requirements for safety class II.

3.4 Class C: Limited voltage
Change the title of the subclause as given above.
Replace the text by:
Modules rated for use in this application class are restricted to systems operating at less than 120 V DC.
Modules qualified for safety through this part of EN 61730 and EN 61730-2 within this application class
are considered to meet the requirements for safety class III.
NOTE Safety classes are defined within EN 61140.

5 Polymeric materials
5.1 General
Replace the second paragraph by:
Exception: Encapsulation materials (such as EVA, PVB, TPU etc.) are not required to meet these
requirements.
5.2 Polymers serving as an enclosure for live parts
In Item c), replace "ANSI/UL 746C" by "EN ISO 4892 series".

5.3 Polymers serving to support live parts
In item b), replace "250 V" by "250".

Add the following notes:
NOTE 1 Polymeric materials having a CTI of 250 or more fall within insulation class IIIa of EN 60664-1.
NOTE 2 The use of polymeric materials requires consideration of the system voltage rating and the pollution class. In this context
Table 4 of EN 60664-1 should be referenced.

Delete item c).
In Item d), replace "ANSI/UL 746C" by "EN ISO 4892 series".

Renumber the note into NOTE 3.

5.4.3 Polymers serving as an enclosure for live parts
Replace "ANSI/UL 746C" by "EN ISO 4892 series".

7.3 Connectors
Add the following sentence:
The standardization of connectors for PV application is an ongoing activity in CENELEC. This subclause
will be superseded by a future European Standard.

7.3.1 Replace "IEC 60130 series" by "EN 61984".

7.3.3 Replace "IEC 61721" by "IEC 60512-5-1" and "EN 60512-5-2".

11 Marking
Add the following sentence:
The marking should be done in conformance with EN 50380.

11.1 Add to the list:
– application class of the product;
– for class A modules, the Safety Class II symbol (see IEC 60417, symbol 5172).
