The mains voltage for power-level terminals is not provided via the potential jumpers. It is
either supplied to the power-level terminal via a power connector or led between directly
adjacent power-level terminals via power bridges.
The mains voltage must have the following values:
The frequency of the mains voltage must be 50 Hz or 60 Hz.
The maximum current carrying capacity for the incoming mains must be 20 A. If this value
is reached, it must be reinjected.
