Installing the Device
2.5 Grounding the device
If the ground terminal on the power supply module(s) is connected to safety Earth,
a connection from the chassis ground terminal is not required.
Functional ground
EMC disturbances are diverted to ground via the functional ground. This ensures the
immunity of the data transmission.
The functional ground must be implemented with low impedance. The connection of
the functional ground must be established directly on the mounting plate or the DIN
rail terminal.
