Only use shielded cables and connection elements that meet the requirements of cat-
egory 5, class D according to IEC 11801 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.

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.
