• Select the power cable in accordance with relevant local and national regulations.

• Wire size must comply with local and national code.

CAUTION

• Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene

sheathed flixible cord. (Code designation H07RN-F or H05RN-F )

• You should connect the power cable into the power cable terminal and fasten it with a clamp.

• The unbalanced power must be maintained within 10 % of supply rating among whole indoor units.

• If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power

is exceeded over 10% of supply rating, the indoor unit is protected, stopped and the error mode

indicates.

• To protect the product from water and possible shock, you should keep the power cable and the

connection cord of the indoor and outdoor units in conduit.

• Connect the power cable to the auxiliary circuit breaker.

• An all pole disconnection from the power supply must be incorporated in the field wiring[≥1/8" (3

mm)].

• You must keep the cable in a protective conduit.

• Keep distances of 2" (50 mm) or more between power cable and communication cable.

• Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must

consider another power supplying method.

• The circuit breaker(ELCB or MCCB+ELB) capacity should be increased if many indoor units are

connected to one breaker.

• Use round pressure/crimp terminal for connections to the power terminal block.

• For wiring, use the designated power cable and connect it firmly, then secure to prevent outside

pressure being exerted on the terminal board.

• Use an appropriate screwdriver for tightening the terminal screws.

A screwdriver with a small head will strip the head and make proper tightening impossible.

• Over-tightening the terminal screws may break them.

• See the table below for tightening torque for the terminal screws.
