Electrical connections

• Make refrigerant connections before electrical connections. When
disconnecting, disconnect electrical connections before refrigerant
connections.
IMPORTANT:
Make ground connection prior to any other electrical connections.
Note:
All field electrical connections are the responsibility of the installer.
Refer to the indoor unit installation manual for sizing the connection
wires between units.
• Remove electric box cover.
• Make electrical connections between units prior to proceeding to
mains supply unit connection.
• Connect the wires to the terminals according to the wiring diagram
and firmly tighten.

Notes:
1. Unit is suitable for indoor and outdoor installation.
2. Starting current duration is usually lower than 1 sec.
3. Wire size shown applies to line length up to 15 m.
4. If the indoor unit is provided with an electric heater, consult indoor unit installation manual for correct sizing of the wires.
5. Data refer to the outdoor unit only.
6. The mains supply connecting cable must be H07 RN-F (60245IEC66) type, synthetic rubber insulation with neoprene coating.

• For 230 V ~ 1 pH 50 Hz single-phase unit
Before proceeding with the unit connection to the mains supply locate
live L and neutral N, then make connections as shown in the wiring
diagram.
• For 400V 3N ~50 Hz three-phase unit
Before proceeding with the unit connection to the mains supply locate
live L1,L2,L3 and neutral N, then make connections as shown in the
wiring diagram. When the electric supply cables L1 (R), L2 (S), L3 (T)
are connected inversely, a special "PSC" phase inversion protection
device blocks the compressor to prevent the same from rotating
inversely. In this case, switch off the electrical supply and check the
correctness of the sequence of the cables of the supply line connected
to the main terminal block (they are probably inverted).
The compressor will only be allowed to work if the phase sequence is
correct.
The phase sequence protection device also continuously monitors the
electrical supply line and if one of the phases is completely missing it
blocks the compressor.
The device only re-starts the compressor after the supply line is
correctly restored.
All the three phase compressors have identical internal wiring.
For this reason when the correct phase connections for a specific
system have been determined, the rotation direction will always be
correct if the same connections are made to the terminal block (for the
other equipment).
• Inside the electrical installation there must be installed an all
phase disconnector with a contact opening of at least 3,0 mm, the
disconnecting switches from the mains power supply should have
a contact gap (4 mm) such that total disconnection can be ensured
under the conditions provided for by overvoltage class III.
• The mains supply indoor unit – outdoor unit connecting cable must
be H07 RN-F (60245IEC66) type, synthetic rubber insulation with
neoprene coating.
Note:
After connections have been completed, close the electric box cover.
