EtherCAT IN (X14) & EtherCAT OUT (X15)
Wrong plugging may cause hardware damage
Even though both EtherCAT sockets are prepared for identical external wiring, make sure to always con-
nect them as follows.
• Use only standard Cat5 cables with RJ45 plug, such as maxon’s «Ethernet Cable» (422827).
• Use EtherCAT IN (X14) as «Input».
• Use EtherCAT OUT (X15) as «Output».
For detailed information
