Illustration 7.44 Interconnect Diagram, E- and F-Frame Frequency Converters
Very long control cables and analog signals may result in 50/60 Hz earth loops due to noise from mains supply cables. If
this occurs, it may be necessary to break the screen or insert a 100 nF capacitor between screen and chassis. Connect the
digital and analog inputs and outputs separately to the common inputs (terminal 20, 55, 39) of the frequency converter to
avoid ground currents from both groups affecting other groups. For example, switching on the digital input may disturb the
analog input signal.
