Overview

EN 60335-2-76:2005/FprAF:2013 is a draft amendment (prAF) to the European safety standard EN 60335-2-76 covering household and similar electrical appliances - particular requirements for electric fence energizers. Prepared by CLC/TC 61, the draft (2012) introduced additional requirements for cascading intelligent electric fence energizers (devices with dedicated measurement terminals). Note: the CLC project was stopped after a negative vote (2014-11-19), so this document remained a draft amendment and was not adopted as a final European Standard.

Key topics and technical requirements

The draft amendment adds a new normative Annex ZBB addressing cascading intelligent energizers. Major technical points include:

• Definitions

  • Cascading intelligent electric fence energizer: unit with one or more measurement terminals in addition to output terminals.
  • Measurement terminal: intended only for monitoring a neighbouring fence; it must not supply impulses.

• Marking and instructions

  • Instructions must state that measurement terminals may only be connected using the provided high-voltage insulated connecting leads to prevent inadvertent contact with two independent fences.

• Leakage current & electric strength

  • Test voltages: apply a test voltage of 2 U but not less than 10 000 V between measurement terminal contact and the fence circuit. For mains-operated or mains-capable battery units a similar test is required between measurement terminal and supply circuit.

• Construction and tests

  • Measurement terminals must not emit pulses; compliance is verified by measuring peak voltage (must not exceed SELV values).
  • Each measurement terminal requires a high-voltage insulated connecting lead of at least 2.5 m; insulation must withstand normal-use electrical stress and be tested at 20 000 V for 15 minutes with no breakdown.
  • Accessible parts: measurement terminals must be enclosed so no unintended electric path is accessible (tested with probe B of EN 61032).
  • Visual differentiation: measurement terminals must be located on the opposite façade to output terminals and be of different geometric shape and colour.
  • Fault behaviour: if abnormal incoming pulses are detected from another energizer, the device must stop emitting pulses immediately and may only resume after at least 10 s. A defined verification procedure with six abnormal pulses (1.5 s spacing, 1 000 V peak, specified energy and load ranges) is included.

Applications and who uses this standard

This standard (and draft amendments) is relevant to:

• Manufacturers of electric fence energizers designing cascading or intelligent systems.
• Product safety engineers and conformity assessors validating designs against electrical strength and leakage requirements.
• Test laboratories performing high-voltage, insulation and functional fault tests.
• Livestock facility designers and installers specifying safe fence energizers for farms and animal containment.
• Regulators and certification bodies reviewing safety documentation for energizers.

Related standards

• EN 60335 series (general safety requirements for household and similar electrical appliances).
• EN 61032 (test probe B) referenced for accessibility/testing.

This draft amendment prAF, if approved, will modify the European Standard EN 60335-2-76:2005; it is submitted
to CENELEC members for CENELEC enquiry.
Deadline for CENELEC: 2013-03-15.

It has been drawn up by CLC/TC 61.
