ELECTRICAL WIRING
This air conditioner must be installed in accordance with national wiring regulations.
Cables connected to outdoor unit must be approved polychloroprene sheathed type 60245 IEC57 or H05RN-F/H07RN-F or heavier.
The units must be connected to the supply cables for fixed wiring by qualified technician.
Circuit breaker must be incorporated in the fixed wiring in accordance with the national wiring regulations.
The circuit breaker must be approved, suitable for the voltage and current ratings of equipment and have a contact separation by 3mm in all poles.
When the supply cable is damaged, it must be replaced by qualified technician.
WARNING
Be sure to install a current leakage breaker, main switch and fuse to the main power supply, otherwise electric shocks may result.
Be sure to connect the unit to secure earth connection.
If the earthing work is not carried out properly, electric shocks may result.
Wiring shall be connected securely by using specified cables and fix them securely so that external force of the cables may not transfer to the terminal
connection section.
Imperfect connection and fixing leads to fire, etc.
Ensure to connect the electrical cable connections and clamp the wires securely to the terminal connections using cord clamps so that no undue force is placed
on the wires (power source cable, indoor/outdoor connection cables, earth lead wire).
Do not install a phase advance capacitor for power factor improvement. (It does not improve the power factor and will cause abnormal overheating.)
Do not bind the excess cables together and place them inside this unit.
Protect the electrical cable with the protective bushing provided so that the cables do no get damaged on the knock hole or etched portions. If there is space
between the electrical cables and the protective bushing occurs, seal it accordingly.
Tie the cables with the provided binding strap so that they do not touch the compressor and the tubes.
When setting up the cables, inside of unit install properly so that the front panel will not lift up. Make
sure that front panel mount correctly.
Use a round type terminal with an insulation sleeve for connecting to the terminal block.
Use the appropriate screwdriver for tightening the terminal screws. Small sized screwdriver damages
the head of the screw and cannot tighten it properly.
There is risk of damaging the screw if the terminal screw is over tightened. Tighten with the appropriate
torque.

Be sure to connect the wires correctly to terminal board with connecting the crimp type ring terminal to the wires.
If connecting two separate wires to a single crimped terminal, place the two crimped terminal wires together as
shown in Fig. A.
(If the arrangement shown in Fig. B is used, poor contacts or contact damage may result.)
