: Applies to systems operating up to 1000 V AC or 1500 V DC . Frequency : Covers supply frequencies up to 200 Hz .

EN 60204-1, titled "Safety of machinery – Electrical equipment of machines – Part 1: General requirements," provides the technical foundation for the design and installation of electrical equipment for non-portable machines. It is the European harmonization of the international standard, ensuring that machines sold across Europe meet uniform safety benchmarks. Scope of the Standard

But what exactly does this standard cover, and why is it considered the cornerstone of electrical equipment safety? This article breaks down the essentials of the standard and guides you on how to access the documentation correctly.

: As he traced the old wiring, Leo realized the machine lacked proper protection against electric shock. He consulted

| Step | Clause | Action | | :--- | :--- | :--- | | 1 | 5.3 | Verify incoming main switch is lockable and rated for motor starting (AC-23A). | | 2 | 7.2 | Check that all enclosures are at least IP54 for industrial environments. | | 3 | 8.2.3 | Confirm protection against short-circuit (breakers or fuses) is coordinated. | | 4 | 9.2.5.4 | Test emergency stop reset – does it require a manual reset (not auto restart)? | | 5 | 12.3 | Inspect all wire colors: Protective earth = green/yellow, neutral = light blue. | | 6 | 18.2 | Perform the verification tests (insulation resistance, continuity, functional tests). | | 7 | Annex B | Complete the "Checklist for electrical equipment of machines". |

: Comprehensive technical documentation must cover the machine’s full lifecycle, and verification through testing (like insulation resistance) is mandatory. Strategic Importance for Manufacturers
