Illustration 1.1 Diagram showing all electrical terminals without options.
Terminal 37 is the input to be used for Safe Stop. For instructions on Safe Stop installation please refer to the section Safe Stop Installation of
the Design Guide.
* Terminal 37 is not included in FC 301 (Except FC 301 A1, which includes Safe Stop).
Terminal 29 and Relay 2, are not included in FC 301.
Very long control cables and analogue 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, it may be necessary to break the screen or insert a 100 nF capacitor between screen and chassis.
The digital and analogue 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.
