Very long control cables and analog 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 n F capacitor between screen a n d chassis.
The digital and analog in- and outputs must be connected separately to the FC 300 common
inputs (term
inal 20, 55, 39) to avoid ground curre nt s from both groups to affect other groups. For
example, switching on the digital input may disturb the analog input signal.
