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 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.
