Terminal 37 is used for Safe Stop. For Safe Stop installation instructions, refer to the Design Guide.
* Terminal 37 is not included in FC 301 (except frame size A1). Relay 2 and terminal 29 have no function in FC 301.
** Do not connect cable screen.
Very long control cables 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, it may be necessary to break the screen or insert a 100 nF capacitor between screen 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.
