Very long control cables and analogue signals occasionally
result in 50/60 Hz ground loops due to noise from mains
supply cables.
In this case, break the screen or insert a 100 nF capacitor
between screen and chassis.
The digital and analogue inputs and outputs must be
connected separately to the common inputs (terminal 20,
55, 39) to avoid ground currents from both groups to
affect other groups. For example, switching on the digital
input disturbs the analogue input signal.
