Terminal
37 is the input to be used for Safe Stop. For instructions on Safe Stop installation, refer to the section Safe Stop Installation in
the Design Guide.
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.
