Danfoss VLT CDS302 User Manual

3.3.11 Electrical Installation, Control Cables
Terminal 37 is the input to be used for Safe Stop. Control
cables more than 100 m (330 ft) and analog signals may in
rare cases and depending on installation result in 50/60 Hz
earth loops due to noise from mains supply cables. If this
occurs, break the screen or insert a 100 nF capacitor
between screen and chassis. The digital and analog in- and
outputs must be connected separately to the frequency
converter common inputs (terminal 20, 55, 39) to avoid
ground currents from both groups to affect other groups.
