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.
The device has a grounding screw (filister head screw with clamping washer and washer) on
the bottom of the enclosure for the functional ground:
