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. 
 
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. 
 
 
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. 
 
 
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.
