Use the same power supply, circuit breaker and leakage protective device for the indoor units connected to the same outdoor unit.
When connecting to the power supply terminal, use the circular wiring terminal with the insulation casing (see Figure 9.1).
If circular wiring terminal with the insulation casing cannot be used, please make sure that:
• Do not connect two power cords with different diameters to the same power supply terminal (may cause overheating
of wires due to loose wiring) (See Figure 9.2).
Use power cord that conforms to the specifications and connect the power cord firmly. To prevent the cord from being
pulled out by external force, make sure it is fixed securely.
