WARNING
Danger to life when live parts are touched on damaged motors/devices
Improper handling of motors/devices can damage them.
For damaged motors/devices, hazardous voltages can be present at the enclosure or at
exposed components.
• Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
•
Do not use any damaged motors/devices.
WARNING
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
•
As a minimum, connect cable shields and the conductors of power cables that are not
used (e.g. brake cores) at one end at the grounded housing potential.
WARNING
Danger to life due to electric shock when not grounded
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
•
Ground the device in compliance with the applicable regulations.
WARNING
Danger to life due to electric shock when opening plug connections in operation
When opening plug connections in operation, arcs can result in severe injury or death.
•
Only open plug connections when the equipment is in a no-voltage state, unless it has
been explicitly stated that they can be opened in operation.
