Select the power cable in accordance with relevant local and national

regulations.
Wire size must comply with local and national code.

Power 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 IEC 66 / CENELEC: H07RN-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 out-
door units in the iron pipe.
Connect the power cable to the auxiliary circuit breaker.

An all pole disconnection from the power supply must be incorporated
in the fixed wiring(≥3mm).
You must keep the cable in a protection tube.

Keep distances of 50mm 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) should be considered more

capacity if many indoor units are connected from one breaker.
Use round pressure 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.
