Risk of damage to the device!
Bring the EtherCAT/EtherCAT P system into a safe, powered down state before starting installation, disas-
sembly or wiring of the modules!
Two M8 sockets at the upper end of the modules are provided for supply and downstream connection of
EtherCAT P:
• IN: left M8 socket for EtherCAT P supply
• OUT: right M8 socket for downstream connection of EtherCAT P
The metal threads of the M8 EtherCAT P sockets are internally linked to the FE connection via high
impedance RC combination. See chapter Functional earth (FE) [} 14].
