• 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.
Electrical connections
• 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).
• According to the installation instructions, 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, replace electric box
cover.
Notes: 1. Unit is suitable for 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 referred to the outdoor unit only.
6. The mains supply connecting cable must be H07 RN-F (60245IEC66) type synthetic rubber insulation with neoprene coating.
