4.2.4 Power Connection
4.2.4.1 Power Connection
The feeding and forwarding of supply voltages is done via two M8 connectors at the bottom end of the
modules:
• IN: left M8 connector for feeding the supply voltages
• OUT: right M8 connector for forwarding the supply voltages

3 GNDs* *) may be connected internally to each other depending on the module: see specific
module descriptions
4 GNDp*
The pins M8 connectors carry a maximum current of 4 A.
Two LEDs display the status of the supply voltages.
Attention
Don't confuse the power connectors with the EtherCAT connectors!
Never connect the power cables (M8, 24 V
DC
) with the green marked EtherCAT sockets of
the EtherCAT Box Modules! This can damage the modules!
Control voltage Us: 24 V
DC
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the 24 V
DC
control
voltage Us. The control voltage is electrically isolated from the fieldbus circuitry.
