Machine defaults to taking voltage at 380V, but it can still operate up to 400V.

You can change the maximum voltage to 415V using the password. Going higher
than that has the potential to damage the machine, and we will not provide
warranty coverage in that case.

If your voltage consistently exceeds 410V, please obtain a voltage regulator.
