1.8 ELECTRICAL CONNECTION.

The appliance has an IPX5D protection degree; electrical safety of
the appliance is achieved only when it is connected properly to an
efficient earthing system, as specified by current safety standards.
ATTENTION:
the manufacturer declines any respon-
sibility for damage or physical injury
caused by failure to connect the boiler
to an efficient earthing system or failure
to comply with the CEI reference standards.
• Open the control panel connections compartment (Fig. 5).
To carry out electrical connections, all you have to do is open the
connections compartment as follows.
- Disassemble the grid (1) (Fig. 41).
- Remove the caps, loosen the fastening screws and pull the front
panel (5) towards you (Fig. 42).
- Remove the cover (b fig. 5).
1) Loosen the screws (a).
2) Remove the cover (b) from the control panel (c).
- At this point, it is possible to access the terminal board (d).
Also ensure that the electrical installation corresponds to maxi-
mum absorbed power specifications as shown on the boiler data
nameplate. The boilers are supplied complete with a "X" type
power cable without plug.
ATTENTION:
the power supply cable must be connect-
ed to a 230V ±10% / 50Hz mains supply
respecting L-N polarity and earth con-
nection; this network must also have
a multi-pole circuit breaker with class
III overvoltage category in compliance
with installation regulations.

To protect from possible dispersions of DC voltage, it is necessary
to provide a type A differential safety device.
It is recommended to contact a qualified company for replacement
to avoid a hazard. The power cable must be laid as shown (Fig. 4).
If the network fuse on the integrated P.C.B. needs replacing, this
must also be done by qualified personnel: use a 3.15 A F (fast) 250
V fuse (size 5 x 20).
For the main power supply to the appliance, never use adapters,
multiple sockets or extension leads.
Installation with system operating at direct low temperature.
The boiler can directly feed a low-temperature system by acting
on parameters "S5" and S6" (Par. 3.11). In this situation it is good
practice to insert a relevant safety kit (optional) made up from a
thermostat (with adjustable temperature). The thermostat must
be positioned on the system flow pipe.
