Warning
Leave the water heater electrically isolated until you are ready to commission it.
Caution
The water heater is phase-sensitive. It is absolutely essential to connect the mains live
(L) to the live of the water heater and the mains neutral (N) to the neutral of the water
heater. The water heater can handle a potential difference between live (L) and neutral
(N), but the potential difference between live (L) and earth has its restrictions, refer to
displayed errors (see 12.1.2), error F19.

Preparation

Remove the cover of the water heater to make the electrical section and the terminal block
visible:
