Handling restrictor collars for touch protection

Handling restrictor collars for touch protection and when connecting cables
Restrictor collars are used to provide touch protection in accordance with IEC 60529. They
must be removed and adapted if necessary before the line supply conductor and/or motor
cable is connected, after which they must be reattached. To adapt the touch protection, see
Connecting the power cables (Page 617).
Exception: The cross-section of the connected cables is large enough to ensure that the
threaded bolts and the ends of the cables cannot be touched when the cover is closed.
The following components are supplied with restrictor collars as standard:
● Active Line Modules 36 kW and higher
● Smart Line Modules 36 kW and higher
● Basic Line Modules 100 kW and higher
