Electrical connections

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.
Caution
There must be no potential difference between neutral (N) and earth (A). Use an isolating
transformer (see section 8.8.3.1) in the supply circuit when there is a potential difference.

Preparation

Remove the cover of the water heater to make the electrical section and the terminal block
visible:
1. Use a hex driver to remove the screw (1) at the cover.
2. Hold the cover at the sides.
3. Lift the cover and take it from the water heater.
