The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
8.6.9 Control Card, RS485 Serial Communication
Terminal number
68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61
Common for terminals 68 and 69
The RS485 serial communication circuit is galvanically isolated from the supply voltage (PELV).
8.6.10 Control Card, USB Serial Communication
USB standard
1.1 (full speed)
USB plug
USB type B plug
Connection to the 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 drive.
