CAUTION
• Select the power cable in accordance with relevant local and national regulations.
• Wire size must comply with local and national code.
• For the power cable, use the grade of H07RN-F or H05RN-F materials.
• 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 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 (≥ 3 mm).
