Illustration 1.2 Diagram Showing All Electrical Terminals without Options
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 chassis.
The digital and analog inputs and outputs must be connected separately to the common inputs (terminal 20, 55, 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.
