Terminal 37 is used for Safe Torque O. For Safe Torque O installation instructions, refer to the VLT

Safe Torque O Operating Instructions.
* Terminal 37 is not included in FC 202 (except enclosure size A1). Relay 2 and terminal 29 have no function in VLT

Long control cables and analog signals may in rare cases,
and depending on installation, result in 50/60 Hz ground
loops due to noise from mains supply cables.
If this occurs, it may be necessary to break the shield or
insert a 100 nF capacitor between shield and enclosure.
Connect the digital and analog inputs and outputs
separately to the common inputs (terminals 20, 55, and 39)
of the frequency converter to avoid ground currents from
both groups to aect other groups. For example, switching
on the digital input may disturb the analog input signal.
