Operating Guide | VLT® Midi Drive FC 280
Output voltage
Maximum load
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.

Control Card, RS485 Serial Communication

9.6.8
Terminal number
Terminal number 61
The RS485 serial communication circuit is galvanically isolated from the supply voltage (PELV). It is used in production, and not
recommended for fieldbus application.

Control Card, USB Serial Communication

9.6.9
USB standard
USB 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.
