Electric wiring
WARNING
The appliance shall be installed in accordance with national wiring regulations.
Capacity shortages of the power circuit or an incomplete installation may cause an electric shock or
fi
re.
CAUTION
• Perform wiring of power supply complying with the rules and regulations of the local electric company.
• Do not connect 380V - 415V power to the terminal blocks for control cables (U1, U2, U3, U4, U5, U6, U7, U8);
otherwise, the unit may break down.
• Be sure that electric wiring does not come into contact with high-temperature parts of piping; otherwise, the
coating of cables may melt and cause an accident.
• After connecting wires to the terminal block, take off the traps and
fi
x the wires with cord clamps.
• Follow the same structure for both the control wiring and refrigerate piping.
• Do not conduct power to indoor units until vacuuming of the refrigerant pipes has
fi
nished.
• For the wiring of power to indoor units and that between indoor and outdoor units, follow the instructions in the
installation manual of each indoor unit.

Power wiring selection
• Select the power supply cabling of each outdoor unit from the following speci
fi
cations:
Cable 5-core, in conformance with design H07 RN-F or 60245 IEC 66.
• To decide nominal cross sectional area of conductor, refer to following table of Maximum Overcurrent Protection
(Amps).
