Internal grounding through RFI capacitor,
which reduces electromagnetic radiation.
In a situation with higher requirements for

an EMC filter can be installed. As a
reference, the diagram on the right is a
symmetrical grounding power system.
Y connection (Star Connection) with stable neutral
grounding point.
