IEC/EN 60204-1: Safety of Electrical Equipment for Machinery (2018+A1:2025)

Basic standards defining the safety of electrical equipment in machinery. IEC/EN 60204-1, The standard is titled “Safety of Machinery — Electrical Equipment of Machinery — Part 1: General Rules”. This is the European edition of the standard. EN 60204-1:2018+A1, April 2025’Updated with changes (A1). In this article we summarize the scope of the standard and its importance in terms of machine electrical control.

What does IEC/EN 60204-1 cover?

Standard, non-portable machines electrical and electronic equipment It applies to equipment where the supply voltage generally does not exceed 1000 V AC or 1500 V DC. The aim is to ensure the safety of personnel and equipment, to support consistent operation and ease of maintenance. Main topics include:

  • Power supply inlet, main switch (disconnect) and power cut-off procedures
  • Protection against electric shock., protective conductor (PE) and equipotential bonding
  • Control circuits and functions; emergency stop and emergency operations.
  • The layout and installation of the control equipment. panels/enclosures
  • Conductors, cables and installation applications; motors and accessories.
  • Marking, warning signs and reference definitions; technical documentation.
  • Verification (tests): PE continuity, insulation resistance, tensile strength, residual voltage protection and function tests.

EN 60204-1:2018+A1:2025 — current edition

Current edition valid in Europe. EN 60204-1:2018+A1:2025’'tir (April 2025). This edition incorporates the CENELEC joint amendments and amendment A1 to the IEC 60204-1:2016 text; it replaces previous editions. Current assessments regarding machine electrical equipment. to this pressure currently in effect It is recommended to do so accordingly.

Importance of machine electrical control.

IEC/EN 60204-1 is the reference for the electrical side in machine safety assessments and Machinery Safety Regulation (2006/42/EC) It supports compliance studies within the scope. Key topics highlighted in the field audit include: main disconnection and locking (LOTO compliance), PE continuity and equipotential bonding, emergency stop chain, panel interior protection and marking, insulation and voltage withstand tests.
