ELECTRICAL CONNECTIONS

Before carrying out any work, switch off the power supply to the air conditioner.
All the parts and materials supplied on site must comply with the local laws and regu-
lations.
All the connection lines must comply with the electrical wiring diagram. Incorrect con-
nection could cause the air conditioner to malfunction or suffer damage. The wiring di-
agrams are subject to a continuous update. Therefore, it is mandatory to refer to those
on the machine.
The unit and its accessories must only be installed and wired by professionals with the
necessary technical qualifications in installation, conversion, extension and maintenance
of the systems and who are trained to perform operational and safety checks on these
systems. In this manual, these will generally be referred to as "Personnel with specific
technical skills".
In particular, the electrical wirings require checks relating to:
Measurement of the electrical system insulation strength.
Continuity of the protection wires.
To protect the unit against short circuits, mounted on the supply line of an thermomag-
netic isolator switch (IG) with a minimum contact separation of at least 3mm in all poles.
Check the earth cable is connected to the earthling/grounding system of the building
itself.
Ensure that the installation is wired in compliance with the laws and standards in force,
and with the instructions in this manual.
If the power supply cables, earth cables, communication cables or wired panel cables are
damaged, they must be replaced with cables with the same specifications. Have repairs
carried out by "Personnel with specific technical skills".
Ensure that the air conditioner is connected to the power supply or to a power socket
with the correct voltage and frequency as indicated on the data plate. Using power sup-
plies with the incorrect voltage and frequency could damage the unit and consequently
risk starting a fire. The voltage must be stable, without major fluctuations.
The available electric power should be sufficient to supply the air conditioner.
The power supply cable should be safe and secure, in order to avoid damage caused by
pulling out the cable terminal.
Do not make junctions on the power supply cable: use a longer cable. Replacement ca-
bles must have the same specifications. Junctions can cause overheating and/or fires.
Have repairs carried out by "Personnel with specific technical skills".
All the power supply lines must use terminals with wire-end ferrules or single-wire termi-
nals. Stranded cables without wire-end ferrules could cause electrical bridges.
Do not leave any cables in contact with the cooling pipe, the compressor or moving parts
such as the fans.
Do not modify the circuits inside the air conditioner. The manufacturer cannot be held
responsible for any damage or malfunction due to incorrect line connections.
Power supply
220-240V ~ 50Hz
208-230V ~ 60Hz
NOTES:
• The circuit breaker and the cross-section of the cables are dimensioned in relation to the maximum
input current; this value indicates the maximum input current while the unit is working, in accordance
with the indications in EN 60335-1 and EN 60335-2-40 standards;
• Reference conditions for calculating the power cable's cross-section (in conformity with IEC 60364-
5-52 standard):
- Multi-pole cable mounted in an insulated duct;
- Ambient temperature 40 °C;
- Cable operating temperature 90 °C;
- Maximum length of cable 15m;
Before accessing the terminals all of the power supply circuits need to be connected.
Air conditioner belongs to class I electrical appliance, so it must be securely grounded.
The yellow and green wire in the air conditioner and the earth wire cannot be used for
other purposes. The cable cannot be secured with a screw through the wire as this could
result in an electric shock.
The user must provide a safe earthling/grounding connection. Check the earth cable is
connected to the earthling/grounding system of the building itself.
Check a suitable differential switch is installed for earthling/grounding electrical dis-
charge. Do not connect the earth cable to the following components:
Water pipes
Gas pipes
Drain pipes
Lightning conductor
Telephone earth cable
Other locations considered unsafe by "Personnel with specific technical skills".

• The circuit breaker is selected by assuming an ambient temperature of 40°C; for other temperatures,
make sure the circuit breaker has appropriate dimensions;
• The circuit breaker must have magnetic and thermal protection to safeguard the system against
short-circuits and overloads; it is recommended to use a thermomagnetic switch with a D curve;
• The circuit breaker must have a contact opening gap of at least 3mm;
