CAUTION
•
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 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.
