Connection concept for voltage inputs
The voltage input signals are connected directly to the 14-pole terminal block (E0 … E6 and GND). To minimize the amount of interference coupled into the module via the transmission lines, connection should be made according to the principle explained below.

The GND connections are connected together in the module and are galvanically isolated from the CPU. These GNDs must not be connected to the CPU, process GNDs or ground !
If shielded cables are used, the shielding should be connected to an earthing rail.
