The unit's electrical safety is only guaranteed when correctly connected to an
efficient earthing system executed according to current safety standards. Have
the efficiency and suitability of the earthing system checked by professionally
qualified personnel. The manufacturer is not responsible for any damage
caused by failure to earth the system. Also make sure that the electrical system
is adequate for the maximum power absorbed by the unit, as specified on the
boiler dataplate.
The boiler is prewired and provided with a Y-cable and plug for connection to the elec-
tricity line. The connections to the grid must be made with a permanent connection and
equipped with a bipolar switch whose contacts have a minimum opening of at least 3
mm, interposing fuses of max. 3A between the boiler and the line. It is important to re-
spect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green
wire) in making connections to the electrical line. During installation or when changing
the power cable, the earth wire must be left 2 cm longer than the others.
B
The user must never change the unit's power cable. If the cable gets damaged,
switch off the unit and have it changed solely by professionally qualified person-
nel. If changing the electric power cable, use solely
mm2 cable with a maximum outside diameter of 8 mm.

CAUTION: The room thermostat must have clean contacts. CONNECTING
230 V. TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPA-
RABLY DAMAGE THE ELECTRONIC CARD.
When connecting a remote timer control or a timer switch, do not take the pow-
er supply for these devices from their cut-out contacts. Their power supply must
be taken with a direct connection from the mains or with batteries, depending
on the kind of device.
Connect the probe to the respective terminals. The maximum permissible length of the
electric cable connecting the boiler - external probe is 50 m. A common 2-wire cable can
be used. The external probe should preferably be installed on the North, North-West wall
or on the wall facing most of the main living-room. The probe must never be exposed to
the early morning sun, and in general (as far as possible) it should not be exposed to
direct sunlight; protect it if necessary. In any case, the probe must not be installed near
windows, doors, vents, flues or heat sources that could affect the reading.

The electrical terminal block is located inside a sealed box at the bottom left of the cab-
inet. Make the electrical connections as shown in the wiring diagram on sec. 64 and run
the cables through the special cable glands.

2. Carry out all the electrical connections (terminals 4 to 24) on module no. 1
3. On the remaining modules only connect the power supply and possible contacts for:
burner lit (300), fault contact (301) and remote reset input (302).
4. Switch on the power to the entire cascade
5. After the "FH" procedure, check correct operation of the cascade:
• Module 1: arrow symbol at top left of the display
• Module 2: arrow symbol at bottom right of the display
• Module 3: arrow symbol at bottom right of the display
• Module 4: arrow symbol at top right of the display
If this does not occur, disconnect the power and check the wiring in fig. 32.
All adjustments must be made on all the modules.
If the electrical connection of a module is disconnected for any reason, module 1 will ac-
tivate fault .
If the electrical connection of a module is disconnected for any reason, the next module
will activate fault .
