ELECTRICAL CONNECTION
The electrical power supply must be con-
nected to terminals L and N and to the panel
complying with all phase and neutral posi-
tions 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.
