EVS-EN IEC 60204-11:2019

IEC 60204-11 applies to electrical and electronic equipment and systems to machines. It provides requirements and recommendations relating to the high-voltage electrical equipment (HV equipment) of machines together with its associated low-voltage electrical equipment (LV equipment). IEC 60204-11 includes a group of machines working together in a coordinated manner, which operate at nominal voltages above 1 000 V AC or 1 500 V DC and not exceeding 36 kV AC or DC with nominal frequencies not exceeding 60 Hz.

The requirements and recommendations help to promote the safety of persons and property, consistency of control response and maintainability.

This standard has been technically revised and contains significant changes:
– aspects of risk assessment, which are mirrored by ISO 12100,
– equipotential bonding and earthing,
– EMC and power quality,
– HV switchgear and controlgear,
– creepage distances for conductors and slip-ring assemblies,
– a list of machinery using HV equipment, in Annex A.

IEC 60204-11 has been updated and improved to reflect the experience gained with the first edition and the evolution of high-voltage equipment. The text of IEC 60204-11:2018 has been approved in Europe as EN IEC 60204-11:2019 without any modification and it supersedes EN 60204-11:2000.
