A = analog, D = digital
Terminal 37 is 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).
Relay 2 and Terminal 29, have no function 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.
