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 380-415 V power to the terminal blocks for control
cables (U1, U2, U3, U4); 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.
• 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.
