In special cases you may attach the earth wire straight to the module.
Information
Earth wires should be short and have a large surface (copper mesh). Refer to

for further details
Bus Coupler
The system power supply connects to the bus coupler through a 2-pole plug-type terminal block with a
bolt flange. Since the bus coupler supplies power to both the E-bus and the logic circuits of the I/O
modules, its power consumption depends on the number of I/O modules connected.
Power to the I/O module outputs is supplied separately.

I/O Modules
The I/O supply connects to the I/O module using plug-type terminal blocks with different numbers of
poles.
The bus coupler supplies power to the logic circuits of I/O modules without their own micro-controller.
Modules equipped with a micro-controller may feature a power supply unit that power is supplied to
through the IO connector.
