Avoid Loops
When laying LAN cables, roll them tangentially from the cable drum or use
appropriate rotary tables. This prevents loops forming and resulting in kinks and
torsion.
Installing other Cables
Remember that LAN cables must not be subjected to excessive strain and stress
when installed. This can, for example, happen when cables are installed along with
other cables on a common rack or in a common duct (providing this is electrically
permitted) and when new cables are pulled along the same path later (during
repairs or when extending a system). If LAN cables are installed along with other
cables in the same cable channel, it is advisable to pull in the sensitive LAN cables
last.
Attachments to PROFIBUS Cables
The attachment of bus connectors and network components (bus terminals,
repeaters, OLMs, ...) to the electrical PROFIBUS cables is described in the
operating instructions or descriptions of the relevant component .
