Only use shielded cables and connection elements that meet the requirements of cat-
egory 5, class D according to IEC11801 edition 2.0.
The following measures ensure the best possible EMC properties:
• Manually tighten the mounting screws on the connectors, modules
and equipotential bonding conductors.
• Use only connectors with a metal housing or a metalized housing.
• 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.
6.7.2 Bus termination
Bus termination (e.g. with bus terminating resistors) is not necessary. If no slave is
connected to an EtherCAT
®
device, it recognizes this immediately.
