Sto Terminal Xd2.19 (Terminal Xd2.19 Is Fixed Pnp Logic); Control Card, 24 V Dc Output; Control Card, 10 V Dc Output; Digital Outputs - Danfoss VLT HVAC Drive FC 102 Operating Manual

VLT® HVAC Drive FC 102
Operating Guide
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals; however, the USB
ground connection is not galvanically isolated from ground. Use only an isolated laptop as PC connection to the USB connector on
the drive.

Operating Guide.
2 When using a contactor with a DC coil inside with STO, 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 V or 50 V MOV for quicker response time) across the coil. Typical contactors can be
bought with this diode.
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
