Protection of equipment (overcurrent, overload, overspeed protection). Clause 8: Equipotential bonding.
The implementation of EN 60204-1 has significant implications for manufacturers, users, and regulatory bodies. For manufacturers, it necessitates a rigorous approach to the design and testing of electrical control systems. This can lead to increased upfront costs but also results in safer products and reduced liability. For users, the standard enhances machine safety, reducing the risk of accidents and associated costs. Regulatory bodies use the standard as a benchmark for assessing compliance with safety legislation. Controlled stop where power remains available to the
