• Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene
sheathed flexible cord. (Code designation 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.
• 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.
• 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.
