+Here the blue wire was needed to supply the Arduino with 5V, because the USB-connector had an up-bent leg before soldering, and therefore the V+ pin was not connected to the Arduino-PCB. When I fixed this, I removed the blue wire.

+R-Core transformer, 230V to 2x 9V. This type of transformer has the least capacitive coupling. It's good to avoid common mode currents.
