Wiring work
t Select the power cable in accordance with relevant local and national regulations.
t Wire size must comply with local and national code.
t For the power cable, use the grade of H07RN-F or H05RN-F materials.
t You should connect the power cable into the power cable terminal and fasten it with a clamp.
t The unbalanced power must be maintained within 10% of supply rating among whole indoor units.
t 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.
t 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 the iron pipe.
t Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in the fixed wiring[≥0.12inch(3mm).
t You must keep the cable in a protection tube.
t Keep distances of 1.97inch(50mm) or more between power cable and communication cable.
t Maximum length of power cables are decided within 10% of power drop. If it exceeds, you must consider another
power supplying method.
t The circuit breaker(ELCB or MCCB+ELB) should be considered more capacity if many indoor units are connected
from one breaker.
t Use round pressure terminal for connections to the power terminal block.
t For wiring, use the designated power cable and connect it firmly, then secure to prevent outside pressure being
exerted on the terminal board.
t Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the
head and make proper tightening impossible.
t Over-tightening the terminal screws may break them.
t See the table below for tightening torque for the terminal screws.
