Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz - Part 4-7: Portable low voltage decoupling filters - Safety requirements
This European product safety standard applies to the filter part of portable devices for household and similar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple) socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c. to neutral operating in the frequency range 3 kHz to 148,5 kHz and from 1,6 MHz to 30 MHz. The filtering functions are described in EN 50065-4-1. This standard does not cover phase couplers. Portable decoupling filters shall not be used as part of the fixed installation, where EN 50065-4-2 applies. Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter part shall comply with the relevant national standard(s). Appliance inlets and appliance outlets connected to the filter part shall comply with the relevant parts of the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not covered by this standard. This standard can be used for portable mains communication devices when no other product standard exists. This standard can be used for other portable mains filters other than those described in EN 50065-4-1 when no other product standard exists. Filters including batteries are not covered by this standard.

This European Standard was approved by CENELEC on 2004-12-01. 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, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

Foreword
This European Standard was prepared by SC 205A, Mains communicating systems, of 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 EN 50065-4-7 on 2004-12-01.
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) 2006-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-12-01
This safety standard EN 50065-4-7 has no frequency dependent content.
It was originally conceived as a safety document within the EN 50065 set of standards, which have a
frequency of 3 kHz to 148,5 kHz.
When the scope of SC205A was extended to 30 MHz, SC 205A agreed that the scope of the published
safety standard, EN 50065-4-2, Low voltage decoupling filters - Safety requirements, should be amended
to include the band 1,6 MHz to 30 MHz in order to cover the additional set of standards for 1,6 MHz to
30 MHz. This required no technical changes to the body of the document.
In addition, it was agreed that Part 4-7, Portable low voltage decoupling filters - Safety requirements,
should also cover both frequency ranges. For this reason the title of this part of EN 50065 covers the
extended frequency ranges 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz.
When certifying or making declaration of conformity to the Low Voltage Directive 73/23/EEC in order to
CE mark the device it is important to state that the CE marking is only valid for the filter parts of the
product. The plug parts and socket-outlets parts are not covered by the Low Voltage Directive and shall
therefore comply with the relevant national standards.
