E-bus and Module Lock
The system plugs and the module lock are located on the sides of Safety I/O-mdoule. These
contact pins interconnect the modules. They supply power to the module's electronic circuitry
and transfer the EtherCAT signals. Verify that the end cap from the package is in place to
protect the module bus connector on the last module at the right-hand side of a terminal unit
against dirt.
The integrated module lock prevents the modules from coming apart under mechanical load or
vibration.
CAUTION
Interconnecting units of different design
Damage to the unit's mechanical elements
Use approved modules in a c250-S network only.
