ELECTRICAL CONNECTION

The electrical power supply must be
connected to terminals L and N and
to the panel complying with all phase
and neutral positions as shown in
the diagram. If they are not connec-
ted properly, the flame detection cir-
cuit will not work and the boiler will
be shut down. The boiler must be con-
nected 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).

t ed t o an ef f icient gr ounding
system. SIME shall not accept any
liability for damage or injury resul-
ting from failure to ground the boi-
ler. Turn off the power supply before
performing any operations on the
electrical panel.
