The use of repeaters is recommended for cable lengths over 1000 m. Repeaters can
also be used to implement galvanic isolation. Refer to the documentation of the re-
peater manufacturer for more specific details.
Observe the recommendations of CiA (CAN in Automation).
When preparing the cables, ensure that there is a low-resistance connection between
the cable screen and the connector casing (
