4.3.3 Shielding and routing bus cables
NOTICE
Risk of a compensating current flowing as a result of incorrect bus cable type, im-
proper shielding and/or improperly routed bus cables.
Possible damage to property.
• In case of fluctuations in the ground potential, a compensating current may flow
via the bilaterally connected shield that is also connected to the protective earth
(PE). Make sure you supply adequate equipotential bonding in accordance with
relevant VDE regulations in such a case.
Only use shielded cables and connection elements that meet the requirements of cat-
egory 5, class D according to IEC11801 edition 2.0.
Correct shielding of the bus cable attenuates electrical interference that can occur in
industrial environments. The following measures ensure the best possible shielding:
• Manually tighten the mounting screws on the connectors, modules, and equipoten-
tial bonding conductors.
• Use only connectors with a metal housing or a metalized housing.
• Connect the shielding in the connector over a wide surface area.
• Apply the shielding of the bus cable on both ends.
• Route signal and bus cables in separate cable ducts. Do not route them parallel to
power cables (motor leads).
• Use metallic, grounded cable racks in industrial environments.
• Route the signal cable and the corresponding equipotential bonding close to each
other using the shortest possible route.
• Avoid using plug connectors to extend bus cables.
• Route the bus cables closely along existing grounding surfaces.
