Overview

EN 60204-1:2018 - Safety of machinery - Electrical equipment of machines - Part 1: General requirements (CLC adoption of IEC 60204-1:2016 RLV) defines safety principles and general requirements for the electrical, electronic and programmable electronic equipment and systems of machines that are not portable by hand while working. The standard applies from the point of connection of the supply to the machine’s electrical equipment and covers single machines as well as groups of machines operating in a coordinated manner. EN 60204-1:2018 is a technical revision of the previous edition (2005) and introduces significant updates reflecting modern drive systems, EMC, documentation and protective measures.

Key Topics

• Scope and applicability: equipment boundaries, machine groups, and supply connection point.
• Power Drive Systems (PDS): added requirements to address PDS integration, control and safety interfaces.
• Electromagnetic Compatibility (EMC): revised requirements and guidance to reduce interference between control and power electronics.
• Protection and fault management:
  • Overcurrent protection and clarification of its selection and application.
  • Determination of short-circuit current rating (SCCR) for electrical equipment.
  • Updated protective bonding requirements and terminology to improve safety against touch voltages.
• Control and safety functions: reorganized Clause 9 covering safe torque off (STO) for drives, emergency stop requirements, control circuit protection and start/reset conditions.
• Marking, documentation and symbols: revised symbols for actuators, enhanced technical documentation requirements, and durability of markings.
• Testing and verification: updates to voltage testing references and verification sequence requirements.
• European common modifications addressing altitude effects, human touch-voltage considerations, and other national conditions.

Applications

EN 60204-1:2018 is used by:

• Machine builders and OEMs designing electrical systems for industrial machinery (machine tools, presses, conveyors, robotic cells, packaging systems).
• Electrical designers and control engineers specifying wiring, protection, EMC measures and drive integration.
• Safety engineers and risk assessors implementing emergency stop strategies, STO, bonding and verification procedures.
• Compliance teams, notified bodies and test laboratories demonstrating conformity with machinery directives (e.g., 2006/42/EC) and preparing technical files.

Adopting EN 60204-1 helps reduce electrical risk, improve system reliability, and simplify conformity assessment for machinery placed on the European market.

Related Standards

Commonly used alongside EN 60204-1:2018:

• IEC/ISO functional safety standards (ISO 13849, IEC 62061)
• IEC/EN standards for switchgear, transformers and assemblies (IEC 60947, IEC 61439)
• EMC and insulating standards (IEC 61140, IEC 60664-1)
• Marking and safety signage (ISO 7010, IEC 60417)

Keywords: EN 60204-1:2018, safety of machinery, electrical equipment of machines, machine electrical safety, power drive systems, EMC, safe torque off, emergency stop, short-circuit current rating, protective bonding.

SIST EN 60204-1 : 2018
NACIONALNI UVOD
Standard SIST EN 60204-1 (sl), Varnost strojev – Električna oprema strojev – 1. del: Splošne zahteve
(IEC 60204-1:2016, spremenjen), 2018, ima status slovenskega standarda in je enakovreden
evropskemu standardu EN 60204-1 (en), Safety of machinery – Electrical equipment of machines – Part
1: General requirements (IEC 60204-1:2016, modified), 2018.

Ta standard nadomešča SIST EN 60204-1:2006.

NACIONALNI PREDGOVOR
Mednarodni standard IEC 60204-1:2018 je pripravil pododbor Mednarodne elektrotehniške komisije
IEC/TC 44 Varnost strojev – Elektrotehnični pogledi. Vzporedno je standard potrdil tehnični odbor
Evropskega komiteja za standardizacijo v elektrotehniki CLC/TC 44X Varnost strojev: Elektrotehnični
pogledi, katerega tajništvo vodi BSI.

Slovenski standard SIST EN 60204-1:2018 je prevod evropskega standarda EN 60204-1:2018. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/TC MOV
Merilna oprema za elektromagnetne veličine.

Odločitev za privzem tega standarda je 11. novembra 2018 sprejel tehnični odbor SIST/TC MOV Merilna
oprema za elektromagnetne veličine.
