Safety of machinery - electrical equipment of machines
All information relating to device selection in this section applies to
● Operation on TN and TT line supply systems with grounded neutral point and grounded
protective conductor as well as to IT line supply systems
● Operating voltage range from 360 V 3 AC to 440 V 3 AC
6.2 Safety instructions with respect to control cabinet design
Danger to life if the fundamental safety instructions and residual risks are not carefully
observed
If the fundamental safety instructions and residual risks in Chapter 1 (Page 17) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• Include residual risks in the risk assessment.
Danger of injury caused by foreign objects in the device
Parts (e.g. drilling chips, end sleeves) falling into the device can cause short circuits and
damage the insulation. This can lead to serious injuries (arcing, loud bang, pieces flying out
of the equipment).
• Only perform installation and other work when the devices are safely isolated from the
• Cover the ventilation slits during the installation of components in the cabinet and

Electromagnetic compatibility

6.3.1

General information

The electromagnetic compatibility describes – according to the definition of the EMC
directive – the "capability of a device to work satisfactorily in the electromagnetic
environment without itself causing electromagnetic interference which is unacceptable for
other devices present in this environment". To guarantee that the appropriate EMC
standards are observed, the devices must demonstrate a sufficiently high noise immunity,
and also the emitted interference must be limited to acceptable values.
