2.13 Electrical connections
The boiler is equipped with a ready wired power cable which is
to be connected to a 230V~50 Hz network.
If this cable needs to be replaced, an original spare must be
requested 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.
