ELECTRICAL SAFETY OF MACHINERY EN IEC 60204

EN IEC 60204 applies to electrical, electronic and programmable electronic equipment and systems to machines not portable by hand while working, including a group of machines working together in a co-ordinated manner.

This standard can be used to show compliance for CE Marking to the EU Machinery directive 2006/42/EC.

The equipment covered by this part of IEC 60204 commences at the point of connection of the supply to the electrical equipment of the machine.

EN IEC 60204 is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1000 V for alternating current (AC) and not exceeding 1500 V for direct current (DC) and with nominal supply frequencies not exceeding 200 Hz.

This part of EN IEC 60204 does not cover all the requirements (for example guarding, interlocking, or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of machine has unique requirements to be accommodated to provide adequate safety.

EN IEC 60204-1 is used along with specific standards that are considered applicable to components or features of machinery. The collateral standards confirm the safe intended use of the machinery based on the risk assessment of the manufacturer.
