Control card, USB serial communication:
USB standard
1.1 (Full speed)
USB plug
USB type B 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-voltage terminals.
The USB ground connection is not galvanically isolated from protection earth. Use only an isolated laptop as PC connection to
the USB connector on the frequency converter.
