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 fire.
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 fix 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 finished.
• 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 supply specifications
Do not bridge the power between outdoor units
through the equipped terminal blocks (L1, L2, L3, N)
