ELECTRICAL CONNECTION

The electrical power supply must be con-
nected to terminals L and N and to the
panel complying with all phase and neu-
tral positions as shown in the diagram. If
they are not connected properly, the
flame detection circuit will not work and
the boiler will be shut down. The boiler
must be connected up to a single phase
230V-50Hz power supply through a main
switch protected by fuses with at least 3
mm between contacts (fig. 13).
NOTE: The device must be connected to an
efficient grounding system. SIME shall not
accept any liability for damage or injury
resulting from failure to ground the boiler.
Turn off the power supply before perfor-
ming any operations on the electrical panel.
