Input capacitance
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.

See VLT Adjustable Frequency Drives - Safe Torque Off Instruction Manual for further information about terminal 37 and Safe
Stop.
4)
When using a contactor with a DC coil inside in combination with Safe Stop, it is important to make a return way for the
current from the coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 or 50 V MOV for
quicker response time) across the coil. Typical contactors can be bought with this diode.
