3.3.6 USB (J7)

Hot plugging the USB interface may cause hardware damage

If the USB interface is being hot-plugged (connecting while the power supply is on), the possibly high poten-

tial differences of the two power supplies of controller and PC/Notebook can lead to damaged hardware.

• Avoid potential differences between the power supply of controller and PC/Notebook or, if possible, bal-

ance them.

• Insert the USB connector first, then switch on the power supply of the controller.
