Diagram showing all electrical terminals. Terminal 37 is not included in FC 301.
Very long control cables and analogue signals may in rare cases and depending on installation result in 50/60
Hz earth loops due to noise from mains supply cables.
If this occurs, you may have to break the screen or insert a 100 nF capacitor between screen and chassis.
Common for the digital and analog in- and outputs must be connected separately to avoid common mode
currents from one group (i.e. the digital inputs) to affect other groups (i.e. the analog inputs).
