1.9 ELECTRICAL CONNECTION
Disconnect power to the unit before ma-
king any electrical connections.
The appliance has an IPX4D degree of protection; electrical safety
of the appliance is achieved only when it is properly connected to
an efficient earthing system, as specified by current safety stan-
dards.
The manufacturer declines any responsibility for dama-
ge or physical injury caused by failure to connect the in-
door unit to an efficient earthing system or failure to
comply with the IEC reference standards.
Connection cables must respect the prearranged routes.
Use 3 clips (c) (not supplied) to group the individual cables (max.
1.5 mm 2 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 mm
The figure 6 shows cables in a hypothetical connection. To make
the connections based on your own requirements, see the in-
structions below.
Open the control panel connections compartment (Fig. 6).
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 maxi-
mum absorbed power specifications as shown on the indoor unit
data-plate.
Indoor units are supplied complete with a "Y" type power cable
without 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.

) in each fairlead.
If the power cable is damaged, contact a
qualified company (e.g. the Authorised
Technical Assistance Centre) for its re-
placement to avoid a hazard.
The power cable must follow the prescribed route (Par. 1.7); avoi-
ding contact with the side of the frame.
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):
Outdoor 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. 3.12).
Photovoltaic system installation
Connecting the product to a photovoltaic system enhances use of
the outdoor unit when the photovoltaic panels are operating. Car-
ry 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.
It is compulsory to set up separate lines
with different power supply voltages,
particularly it is essential to separate the
very low voltage connections from the
230 V ones.
No product pipes must ever be used to
earth the electric system or telephone li-
nes.
Ensure elimination of this risk before
making the indoor unit electrical con-
nections.
The indoor unit can be electrically con-
nected to outdoor units with very low vol-
tage safety circuits (SELV)
