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 (Uv (U1, U2), Uh (U3, U4), Uc (U5, U6));
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.
• Process both electric wiring and refrigerant piping into the same system.
• Do not conduct power to indoor units until vacuuming of the refrigerant pipes has
fi
nished.
• For the power supply wiring of indoor units, follow the instructions in the Installation Manual of each indoor unit.
