• Connect the power cable to the auxiliary circuit breaker. If every pole fails to connect to the power supply, it must be incorporated in a wire with a contact opening of ≥3 mm.
•Use shield cable (Category 5; less than 50pF/m) for noisy environmental site.
•Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. (Code designation IEC: 60245 IEC 66/CENELEC:
Connecting the cable
Electrical work
(1)For electrical and earth works, comply with the‘technical standards of electrical installations’and the the‘wiring regulations’of the Local wiring regulations.
(2)Tighten the terminal block screw to 1.2~1.8 N•m (1.2~1.8 kgf•cm).
(3)Precautions when connecting terminal blocks of the indoor unit
Before connecting, make sure the connecting part of the terminal socket is facing upwards.

• For the terminal block wiring, use a wire with a ring terminal socket only.
Regular wires without a ring terminal socket may become a fire hazard due to overheating of the electrical contact during
a wiring work.
When you install the unit, make first refrigerant connections and then electrical connections. Connect the air conditioner to grounding system before performing the electrical connection. If unit is uninstalled, first disconnect electrical cables, then refrigerant connections.
If the outdoor unit is more than 5 meters away from the indoor unit, you must extend the cable. The maximum length of the cable is 30(18/24) meters.
