FC 300 Operating Instructions
General Specifications
Control card, RS 485 serial communication:
Terminal number .............................................................................. 68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61 ......................................................................... Common for terminals 68 and 69
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 .......................................................................................................... 1.1 (Full speed)
USB plug .................................................................................................... USB type B “device” 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 FC 300 drive.
