2.12 Electrical connections
The power cable must be connected to a 230V (±10%) ~ 50 Hz
network, observing L-N polarity and the earth connection. The
network must have an omnipolar switch with category III over-
voltage, in compliance with the installation rules.
If this cable needs to be replaced, an original spare must be re-
quested from
Sime
.
Therefore only the connections of the original components as
shown in the table are needed. These are to be ordered sepa-
rately from the boiler.
