3.3.1 Electrical Installation, Control Cables
Very long control cables and analogue signals may in rare cases and depending on installation result in 50/60Hz earth loops
due to noise from mains supply cables.
If this occurs, it may be necessary to break the screen or insert a 100nF capacitor between screen and chassis.
The digital and analog inputs and outputs must be connected separately to the frequency converter common inputs
(terminal 20, 55, 39) to avoid earth currents from both groups to affect other groups. For example, switching on the digital
input may disturb the analog input signal.
