NOTE

•Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. (Code designation IEC:60245 IEC 57 / CENELEC: H05RN-F or IEC:60245 IEC66 / CENELEC H07RN-F)

•This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc (*2) at the interface point between the user's supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc(*2).

Power wiring diagram

Connect the power cable of the outdoor unit after checking that R-S-T-N (3-phase 4 wires) is properly connected. If the power of 380 V is supplied to the N phase, PCB and other electrical parts will be damaged.

INSTALLATION PARTS

NOTE

•Before supplying power to the outdoor unit, be sure to check the voltage of the distribution board. The voltage between phases for the 3 phase 4 wires 380 V is as follows:

R phase and S phase: 380 V

R phase and T phase: 380 V

S phase and T phase: 380 V

R phase and N phase: 220 V

S phase and N phase: 220 V

T phase and N phase: 220 V

•Communication cables between the indoor and outdoor units do not have polarity.
