→ connect the 0 V of the power supply with the protective conductor.
→ if you also wish to use the power supply at terminals 31, 32 for the digital inputs, then you
must connect "DI COM" and "GND IN" with one another at the terminals.
You may use the internal 10 V power supply or an external power supply for the analog inputs.
→ When you use the internal 10 V power supply, you must connect AI 0 or AI 1 with "GND".
