Overview

prEN 60335-2-76 {fragment 2}:2017 is a CLC/IEC committee draft fragment that updates Part 2-76 of IEC 60335 - the safety requirements for electric fence energizers, with a specific focus on electric security fences. This fragment defines new terms, marking, instructions and test requirements for energizers used in security installations, and it addresses synchronized systems where multiple energizers can jointly energize adjacent fences.

Key topics and technical requirements

• Definitions and system types

  • Introduces terms such as security electric fence energizer, impulse timing signal, independent and dependent security energizer, security energizer group and security energizer fence system.
  • Examples of impulse timing signals include wired (RS-485), networked (secure TCP/IP), wireless (LAN/PAN), optical and GPS.

• Type classification

  • Type R energizers: restricted to a maximum output energy/impulse of 2.5 J per fence circuit.
  • Type S energizers: not restricted to 2.5 J per impulse.
  • Rules for permitted combinations in a security energizer group (type R and/or S as allowed).

• Marking and instructions

  • Time-synchronized energizers must carry designated IEC60417 symbols (document uses placeholder symbols).
  • Labels signed by an authorized installer (contact + installation/service date) are required on each energizer in a group.
  • Instructions must detail permitted configurations, hazards, installer responsibilities, permitted models and symbol meanings, and explicit safety warnings (including risk of fatal electric shock).

• Testing and performance

  • Mandatory group testing for permitted configurations, including combined supply-voltage scenarios (mains and battery ranges with multipliers specified) and heating tests.
  • Abnormal-operation and fault testing of impulse timing signals (stop, intermittent, variable/high rate, etc.) to verify safe behavior if synchronization fails.
  • Measurement methods for peak output voltage using capacitive loads (0–200 nF steps) and energy-per-impulse measurement procedures (type R limit 2.5 J).

Applications

• Perimeter security systems (commercial, industrial, sensitive sites)
• Livestock installations and farm perimeter protection (ICS 65.040.10 relevance)
• Manufacturers designing or certifying electric fence energizers for security use
• Test laboratories performing conformity and safety testing of energizers and multi-energizer systems

Who should use this standard

• Electric fence energizer manufacturers and designers
• Authorized installers and system integrators of security fences
• Compliance officers, safety assessors, and testing laboratories
• Standards bodies and regulatory authorities overseeing electrical safety of perimeter protection

Related standards

• IEC/EN 60335-2-76 (base document and earlier amendments listed in the draft)
• Relevant IEC/IEC-CENELEC guidance on electrical safety, EMC and installation practices for electrically-operated farm and security appliances

This fragment is a CDV (Committee Draft for Vote) and was intended to be used for parallel IEC/CENELEC voting in 2017; it was still subject to change at the time of circulation.
