Measurement:
Carry out a socket and see voltage check on the incoming mains supply marked L and N on the white connector block.
The socket and see should pass with a voltage of 207 - 253 as this is the range expected for 230v mains supply in the UK (+/- 10%).
Is the incoming mains voltage acceptable?
Note:
The appearance and layout of the incoming mains connector can vary depending on the PCB version, follow the appropriate image.
