ELECTRICAL CONNECTION

The boiler must be connected to a power supply of 230V/50Hz single-phase + ground, following the instructions below:
The system must be in compliance with the SAFETY REGULATIONS IN FORCE.
- Fit a bipolar line disconnection switch in conformity with CEI-EN regulations
(contact opening of at least 3 mm).
- Respect the L (phase) - N (neutral) connection
- Use cables with a cross-section equal to or greater than 1.5 mm
- Refer to the wiring diagrams in this manual for any electrical operation.
- Make the ground connections to an effective ground system.

CONTROL PANEL

OPERATIONS
Use main switch (11) to power up the panel and all the connected devices.
Switches (12) and (13) in turn, power off the plant burner and pump.
Thermostat (21) is used to regulate boiler working pressure.
Min pressure thermostat stops the plant pump during start up and until the boiler temperature has reached 50°C.
In case of three-phase burners and/or pump or if electrical input exceeds 3A, remote contactors should be provided
between the boiler control panel and the load.
The electric line supplying the boiler control panel should be provided with a protection fuse-switch.
wARNING
• For the electric connection of boilers
exceeding 300.000 kcal/h rated power,
the technician should make ready an
additional (2nd) safety thermostat.
