WARNING
Electric shock due to damaged motors or devices
Improper handling of motors or devices can damage them.
Hazardous voltages can be present at the enclosure or at exposed components on
damaged motors or devices.
• Ensure compliance with the limit values specified in the technical data during
transport, storage and operation.
• Do not use any damaged motors or devices.
WARNING
Electric shock due to unconnected cable shield
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
Electric shock if there is no ground connection
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
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is operation can result in arcing that may
cause serious injury or death.
• Only open plug connections when the equipment is in a voltage-free state, unless it
has been explicitly stated that they can be opened in operation.
