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
supply 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 ground. Use only an isolated laptop as PC connection to
the USB connector on the adjustable frequency drive.
