Danfoss VLT CDS302 Operating Instructions Manual page 159

General Specifications
The RS-485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from
the supplier voltage (PELV).
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-voltage terminals. The USB
ground connection is not galvanically isolated from protection earth. Use only isolated laptop as PC connection to the USB
connector on the frequency converter drive
