Foreword
This amendment to the European Standard EN 50090-2-2 was prepared by the Technical
Committee CENELEC TC 205, Home and Building Electronic Systems (HBES).
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as amendment A1 to EN 50090-2-2:1996 on 2001-07-01.
The following dates were fixed:
- latest date by which the amendment has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2002-08-01
- latest date by which the national standards conflicting
with the amendment have to be withdrawn (dow) 2004-08-01
NOTE  EN 50090-2-2 is listed under the EMC and LV-Directives.
The main reasons for this amendment are
- clarification of the scope, to eliminate the restriction by SELV or PELV (clause 1),
- reduction of the electrical strength test from 2,5 kV AC to 2,0 kV AC, 5 minutes (5.2.3.3 and
5.2.3.4),
- clarification if product standards exist or not (5.2.4.2 and clause 6),
- clarification on "Simple separation" and "Protective separation" (5.2.4.3),
- reference to power line communication (clause 7).

Foreword
Add at the end:
Part 8: Conformity
Part 9: Installation requirements
1 Scope
Replace the first paragraph by
This European Standard defines the general technical requirements of a Home and Building
Electronic System (HBES). It concerns cabling and topology, electrical safety for HBES device
parts, in particular based on SELV or PELV, functional safety, environmental conditions, EMC
requirements and behaviour in case of failures as well as specific HBES installation rules.
Replace the second paragraph by
This standard covers the interface of devices and equipment providing connection to the HBES as
well as separately mounted HBES equipment.
Parts of devices and equipment not providing HBES functionality are not covered by this standard.
This standard is used as a product family standard. The electrical safety part is not intended to be
used as a stand-alone standard. The safety requirements of this standard apply either together with
the relevant product standard for the device or together with the basic safety standards if no
product standard exists.
