ES1: Introduction to the Electrical Equipment of Machinery (EN 60204-1)

Last edit: 27/05/2024

Training Objectives

The training objective is to be able to design and engineer an industrial control panel according to the European Standard EN 60204-1. Since October 2021, the 2006 edition of EN 60204-1 is not anymore harmonised and the new edition has become compulsory. We will also touch on the new editions of IEC 61439-1 and IEC 61439-2 (2020).

Despite adhering to the language of the standard, the training is practical, with several examples.
