Control card, USB serial communication:
USB standard
USB plug
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-volt-
age terminals.
The USB ground connection is not galvanically isolated from protection ground. Use only an
isolated laptop as PC connection to the USB connector on the adjustable frequency drive.
