Note
To increase the mechanical stability, optimized retaining collars
connectors are installed on the bottom part of the housing in the delivery state. These
retaining collars are intended for the Siemens FastConnect connectors.
NOTICE
Make sure you observe the minimum bending radius of the Ethernet cable; otherwise the
shield effect of the cable shield may be impaired. There is also the risk that the
cable shield breaks.
NOTICE
EMC stability is only guaranteed with shielded PROFINET cables.
Critical plant state
