Long control cables and analog signals may in rare cases,
and depending on installation, result in 50/60 Hz ground
loops due to noise from mains supply cables.
If this occurs, it may be necessary to break the shield or
insert a 100 nF capacitor between shield and enclosure.
Connect the digital and analog inputs and outputs
separately to the common inputs (terminals 20, 55, and 39)
of the frequency converter to avoid ground currents from
both groups to affect other groups. For example, switching
on the digital input may disturb the analog input signal.
