ELECTRICAL CONNECTION

The internal unit has an IPX4D degree of protection; electrical
safety of the appliance is achieved only when it is properly con-
nected to an efficient earthing system, as specified by current safe-
ty standards.
The manufacturer declines any responsibility for dam-
age or physical injury caused by failure to connect the
indoor 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.
2
1.5 mm 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 instruc-
tions 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 an "X" type power cable
without plug.
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.

2 ) in each fairlead.
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 Af-
ter-Sales Technical Assistance Centre.
It is recommended to contact a qualified
company (e.g. the Authorised Af-
ter-Sales Technical Assistance Centre)
for replacement to avoid a hazard.
The power cable must be laid as shown (Fig. 6).
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 outdoor unit by connecting
terminals F1 and F2 as shown in the wiring diagram (Fig. 8). The
outdoor unit is powered at 230 V, regardless of 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 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.
