Overview

EN 50065-4-2:2001/A1:2003 is a CENELEC amendment that updates safety requirements for low-voltage decoupling filters used in signalling on low-voltage electrical installations in the frequency range around 3 kHz to 148,5 kHz. This amendment (A1) revises mechanical and thermal safety clauses to ensure safer design and installation of devices that separate mains-borne signalling (powerline communication / PLC) from the power distribution network.

  • Standard type: European (CENELEC) amendment A1 to EN 50065-4-2:2001
  • Relevant to: safety of low-voltage decoupling filters in mains communication systems
  • Approval: CENELEC (approved 2002‑12‑01); national implementation dates specified

Key Topics and Requirements

This amendment focuses on tangible safety provisions; notable changes include:

  • Mechanical connections (clause 19.6)

    • Thread-forming and thread-cutting screws are prohibited for the connection of current-carrying parts.
    • Such screws may be used to provide earthing continuity only if the connection is not intended to be disturbed in normal use and at least two screws are used per connection.
    • Compliance is verified by visual inspection.

  • Resistance to abnormal heat, fire and tracking (clause 21.1)

    • Specifies elevated glow-wire / heat endurance requirements for insulating parts that retain current-carrying or earthing circuit components, depending on overvoltage category:
      • 850 °C for parts when equipment is classified to overvoltage category III
      • 960 °C for parts when equipment is classified to overvoltage category IV

  • Emphasis on inspection-based compliance and clearer classification for thermal/fire performance related to overvoltage categories.

Applications and Who Uses This Standard

EN 50065-4-2/A1 is directly relevant to professionals involved in powerline signalling and mains-communication equipment:

  • Manufacturers and designers of low-voltage decoupling filters and PLC interface hardware
  • Product safety and compliance engineers preparing CE / national declarations
  • Test laboratories assessing mechanical and thermal safety of decoupling filters
  • Installers and system integrators of home/building electronic systems (HBES) and smart grid components
  • Regulators and certification bodies enforcing electrotechnical safety

Practical uses include product design decisions for screw selection and earthing continuity, selection of insulating materials to meet glow-wire requirements, and preparing documentation for conformity assessment.

Related Standards

  • EN 50065 series (other parts addressing signalling on low-voltage installations and compatibility)
  • CENELEC and national electrotechnical safety standards for HBES and mains communication systems
