Pin assignment X30 IN/OUT
Use prefabricated, shielded RJ45 plug connectors to IEC11801 edition 2.0, category 5.
4.3.1
FSE24B – EtherCAT
®
connection
The FSE24B communication option is equipped with two RJ45 connectors for a linear
bus structure. The EtherCAT
®
master is connected (if necessary, via additional
EtherCAT
®
slaves) to X30 IN (RJ45) with a shielded, twisted-pair cable. Additional
EtherCAT
®
units are then connected via X30 OUT (RJ45).

Shielding and routing bus cables
Only use shielded cables and connection elements that also meet the requirements of
category 5, class D according to IEC11801, edition 2.0.
Correct shielding of the bus cable attenuates electrical interference that can occur in in-
dustrial environments. The following measures ensure the best possible shielding:
• Manually tighten the mounting screws on the connectors, modules, and equipotential
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.
