7.9 Bus cables Only cables conforming to the DeviceNet wire specification (www.odva.org)
may be used for a DeviceNet network.
The bus cable must be laid at a distance of at least 20 cm from other cables.
It should be laid in a separate, conductive and earthed cable trunking.
It must be ensured that there are no potential differences between the indi-
vidual stations on the DeviceNet (Perform a potential compensation).
Thick Cable As a standard, the thick cable is used for the trunk line.
Thin Cable The thin cable is used for the drop lines
