Specifications
Control card, RS485 serial communication
Terminal number
Terminal number 61
The RS485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from the
supply 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 protective earth. Use only an isolated laptop as PC connection to
the USB connector on the frequency converter.
