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 IEC 57 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.
WARNING
When the supply cable is damaged, it must be replaced by qualified technician.
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 pipes.
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.

Earth lead wire set up
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.)

Sideways direction
The earth lead wire shall be longer than other lead wires as shown in the
figure for electrical safety in case it slips out of the cord from the anchorage.
Insulate the terminal
section with insulation
sleeves.

Firmly secure the power supply
cable, the internal/external
connections and earth wire.
Tie the insulation pipes so that the
power supply cable, control wires,
and earth lead wire do not come into
contact with the compressor and/or
the exposed pipes.
