Electrical connections and electrical data
Remove electric box cover.
Connect the wires to the terminals according to the wiring diagram
and firmly tighten.
IMPORTANT:
Make ground connection prior to any other electrical
connections.
• Make electrical connections between units prior to proceeding to
mains supply unit connection.
• 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.
• 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.
• Make certain the refrigerant pipes and the electrical
connection lines between the indoor unit and the outdoor
unit have the same colours and reference codes (A, A1, A2,
B, B1, B2) using the special adhesive references supplied.
Note:
All field electrical connections are the responsibility of the
installer.
Note:
After connections have been completed, replace electric box cover.
Notes: 1. Unit is suitable for outdoor installation.
2. Data referred to the outdoor unit only.
3. Starting current duration is usually lower than 1 sec.
4. The section of the cables refers to cables with a maximum length of 15 metres.
5. The mains supply indoor unit – outdoor unit connecting cable must be H07 RN-F (60245IEC66), type synthetic rubber insulation with
neoprene coating.
6. If the indoor unit is provided with an electric heater, consult indoor unit installation manual for correct sizing of the wires.
7. Electrical input refer to each one of the two mains supplies.
