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.
Caution
There must be no potential difference between neutral (N) and earth ( ).
If this is the case, then an isolating transformer (3.10.4 "Isolating transformer")
must be used in the supply circuit.
For more information or to order this isolating transformer, please contact the
supplier.
The figure shows a view of the terminal block, and the table explains the
relevant connections.
