Fundamental safety instructions
2.5 Residual risks of power drive systems
6. Influence of network-connected and wireless communications systems, e.g. ripple-control
transmitters or data communication via the network or mobile radio, WLAN or Bluetooth.
7. Motors for use in potentially explosive areas:
When moving components such as bearings become worn, this can cause enclosure
components to exhibit unexpectedly high temperatures during operation, creating a hazard
in areas with a potentially explosive atmosphere.
For more information about the residual risks of the drive system components, see the
relevant sections in the technical user documentation.
