Click steps to track your progress.
Verify that the power supply to the Wall Connector is nominally within the 200-240 volts range.
If the issue persists, have a qualified electrician remove the Wall Connector from the wirebox.
The electrician should confirm that voltage readings at the terminal block are as expected using a multimeter and record readings for L1 to L2/N, L1 to Ground, and L2/N to Ground.
