Installing LAN Cables

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 .
