Foreword
This document [prEN 50561-2:2015] has been prepared by CLC/TC 210 “Electromagnetic Compatibility
(EMC)”.
This document is currently submitted to the Enquiry.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
The following dates are proposed:
– latest date by which the existence of the EN (doa) dor + 6 months
has to be announced at national level
– latest date by which the EN has to be implemented (dop) dor + 12 months
at national level by publication of an identical
national standard or by endorsement
– latest date by which the national standards conflicting (dow) dor + 36 months
with the EN have to be withdrawn (to be confirmed or
modified when voting)
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this
document.
EN 50561 is currently composed of the following parts:
— EN 50561-1, Power line communication apparatus used in low-voltage installations — Radio
disturbance characteristics — Limits and methods of measurement — Part 1: Apparatus for in-home
use;
— prEN 50561-2, Powerline communication apparatus used in low voltage installations — Radio
disturbance characteristics — Limits and methods of measurement — Part 2: Apparatus for access-
network use (the present document).
The scope is extended to the whole radio-frequency range from 9 kHz to 400 GHz, but limits are formulated
only in restricted frequency bands, which are considered sufficient to reach adequate emission levels to
protect radio broadcast and telecommunication services and to allow other apparatus to operate as intended
at reasonable distance.

1 Scope
This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for
PLC access network communication apparatus that use the low voltage power installation as the
transmission medium. This European Standard applies to equipment that communicate over this medium in
the frequency range 1,606 5 MHz to 30 MHz.
Procedures are given for the measurement of signals generated by the equipment and limits are specified for
the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limit is
specified.
