CAUTION
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB connection is not galvanically isolated from ground protection. Use only isolated laptop/PC as connection to
the USB connector on the adjustable frequency drive or an isolated USB cable/drive.
