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.
The manufacturer declines any responsibility for dama-
ge or physical injury caused by failure to connect the hy-
dronic module to an efficient earthing system or failure
to comply with IEC reference standards.
Connection cables must respect the prearranged routes.
Use 3 clips (c) (not supplied) to group the individual cables (max.
1.5 mm2) into the lower terminal board.
Use the specific fairleads (d) on the left side, making sure to put at
most 2 multi-polar cables (max 3 x 1 mm2) in each fairlead.
As an example, figure 4 shows cables in a hypothetical connection.
To make the connections based on your own requirements, see the
instructions below.
Open the control panel connections compartment
To carry out electrical connections, all you have to do is open the
connections compartment as follows.
1. Remove the front panel.
2. Disassemble the cover.
3. Loosen the screws (a).
4. Remove the cover (b) from the control panel (c).
At this point, you can access the terminal board.
Also ensure that the electrical installation corresponds to the ma-
ximum absorbed power specifications shown on the hydronic
unit rating plate.
The hydronic units are supplied complete with a special "X"-type
power cable without a plug.
The power supply cable must be con-
nected to a 230V ±10% / 50Hz mains sup-
ply respecting L-N polarity and earth
connection; 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.
If the power supply cable is damaged, it
must be replaced by a special cable or as-
sembly, which are only available from the
manufacturer or its Authorised Service
Centre.
It is recommended to contact a qualified
company (e.g. the Authorised After-Sa-
les Technical Assistance Service) for re-
placement to avoid a hazard.
The power cable must be laid as shown (Fig. 5).
If the fuses on the circuit boards need to be replaced, this must also
be done by qualified personnel: use a F3.15A H250V fuse on the
P.C.B.
For the main power supply to the appliance, never use adapters,
multiple sockets or extension leads.
Make the various electrical connections according to your needs
(Fig. 7, 8):
Condensing unit electrical connection
The indoor unit must be coupled to an Audax Pro V2 outdoor unit
by connecting terminals F1 and F2 as shown in the wiring dia-
gram (Fig. 8). The Audax Pro V2 outdoor unit is powered at 230 V,
independently from the indoor unit.
Configure the indoor unit parameters as indicated in paragraph
(Parag. 3.9).
Photovoltaic system installation
Connecting the product to a photovoltaic system enhances use of
the condensing unit when the photovoltaic panels are operating.
Carry out the connection as indicated (Fig. 7).
Dehumidifiers
Carry out the connection as indicated (Fig. 8). To complete the
connection operations, insert the 2-relay Board optional kit.
