Relay Outputs; Control Card Performance; Control Characteristics - Danfoss VLT 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.
The USB ground connection is not galvanically isolated from protective earth. Use only an isolated laptop as PC connection to the
USB connector on the drive.
