Technical parameters
The list of CT coils that are supported by the Audi Wallbox by default can also be obtained
from chapter Set DIP-switches (page 49).
In addition to the CT coil models mentioned in chapter Set DIP-switches, the CT coil models
that are possible to use as default with any variant of the Audi Wallbox are listed.
In addition to the CT coils supported by the Audi Wallbox by default, the Audi Wallbox plus
and pro oer the possibility to also use other CT coils with dierent technical parameters.
However, these parameters need to be congured in the Audi Wallbox's Conguration
Manager during electrical commissioning. The table below is listing the limitations of the
technical parameters, that such CT coils need to full.
