That warning means that if you are using the pololu power module to power the Raspberry you should not use the Raspberry USB-C 5V input.
If you do not use the pololu power module you need a 5V charger to power the Raspberry by the USB-C input as usual but since the MAIANA devices needs 12V, you need to connect 12V SW to the battery.
We need these 2 connections (12V and 12V SW) because 12V SW will trigger the shutdown and the system needs to be powered by 12V until the shutdown ends.
Graphically:
If you are not using neither the power module nor the MAIANA, power the Raspberry by the Raspberry USB-C input as usual.
If you are not using the power module but you are using the MAIANA, this is the wiring:
If you are using the power module and the MAIANA this is the wiring:
