Notes:
① The size of circuit breaker and power cord in above sheet is selected based on the max
power (max current) of unit.
② Above selection requirements of power cord size: Power cord size is based on multicore
copper core cable with operation temperature of 90°C when laying on wire groove at 40°C ambient
temperature (IEC 60364-5-523). If the operation condition is different, please calculate according to
national standard.
③ Above selection requirements of circuit breaker size: Circuit breaker size is based on ambient
temperature of 40°C when the circuit breaker is working. If the operation condition is different, please
calculate according to circuit breaker specification.
(2) Install circuit breaking device near the unit. The minimum distance between each stage of
circuit breaking should be 3mm (The same for both indoor unit and outdoor unit).
