In CPX-AB-4-M12x2-5POL-R and CPX-M-4-M12x2-5POL the metal thread
is connected to FE
Recommendation for the 8-input module:
Use the Festo DUO cable in order to connect two sensors with
one plug at low cost.
The metal thread of these connection blocks is connected
internally with pin 5 (functional earth FE).
