6.3.2 Connecting the functional ground
You must always connect the terminal strip with PE from the central node in the cabinet.
Use the conductor with cable clamp that is included with the Memosens cable to connect the
functional ground to the terminal strip of the CM44xR.
You must only ever connect one functional ground to each screw in the terminal strip.
Otherwise, shielding is not guaranteed.
