Understanding EN 60204-1:2018+A1:2025 – Safety of Machinery Electrical Equipment PDF
EN 60204-1 is a European standard that outlines the safety requirements for the electrical and electronic control systems of machinery. The standard is part of the IEC 60204 series, which is widely adopted across the globe. EN 60204-1 specifically focuses on the safety aspects of electrical control systems, including the design, construction, and testing of machinery.
If you are auditing an industrial control panel or machine build against EN 60204-1, verify these quick points: Is there a clear, lockable main power disconnect?
The protective bonding circuit is one of the most critical safety features required by the standard. en 60204-1 pdf

Clarifications on TN, TT, and IT earthing systems.
Are you designing for a (e.g., CNC, robotics, or packaging)? If you are auditing an industrial control panel
Applying a high AC voltage (usually 1,000 V or twice the rated voltage) for 1 second between the circuit conductors and the protective earthing system to check for insulation breakdown.
While the official standard must be purchased, many companies and organizations offer valuable free resources to help users understand and apply it:

Here's a brief overview:
Measuring resistance between the live conductors and the protective bonding circuit (typically using 500 V DC).
EN 60204-1 is the cornerstone document for anyone involved with industrial machinery across nearly all sectors. It isn't just a theoretical guide; it is a "designated" or "harmonised" standard, which gives it powerful legal and commercial implications.
Preventing people from touching live electrical parts using insulation, enclosures (minimum IP2X or IPXXB protection), or barriers.
