About IEC 60204-1 (Electrical Equipment of Machines)

This event covers the compliance, engineering, and verification requirements defined by IEC 60204-1.

IEC/EN 60204-1 covers the electrical, electronic and programmable equipment of machines: supply connection, protection against electric shock and equipment faults, control circuits and functions, and verification — the electrical backbone every machine's technical file references.

What it regulates

Supply disconnecting devices, protective bonding, control circuit design, stop functions (categories 0/1/2), emergency operations, enclosures, conductor selection, marking, and the electrical verification tests before commissioning.

Who must comply

Machine builders and panel builders for virtually all industrial machinery placed on the EU market; the harmonized route for Machinery Regulation electrical EHSRs.

Key requirements of IEC 60204-1

  • Supply disconnect and prevention of unexpected energization
  • Protection against shock (basic/fault protection) and overcurrent coordination
  • Stop function categories 0, 1, 2 and their assignment
  • Control circuits: supply, protective interlocks, and cableless control
  • Verification: continuity of bonding, insulation resistance, functional testing

Key concepts: IEC 60204-1

Cableless control
Requirements for wireless pendants including stop behavior on signal loss.
Protective bonding circuit
The continuous earthing system tying exposed conductive parts together, verified by continuity testing.
Stop category 0/1/2
Uncontrolled power removal, controlled stop then power removal, and controlled stop with power retained — assigned per function by risk assessment.
Supply disconnecting device
The lockable main disconnect enabling safe isolation for maintenance.

Frequently asked questions: IEC 60204-1

How does 60204-1 relate to ISO 13849?

60204-1 governs the electrical implementation and general control circuits; when a circuit performs a safety function, its integrity (PL/Category) is engineered per ISO 13849-1 on top of 60204-1's electrical rules — the two apply together.

Which verification tests are required before handover?

Verification per clause 18: protective bonding continuity, insulation resistance, and where applicable voltage tests, plus functional testing of all safety-relevant control functions including every stop category and emergency stop.
