V1.1 Chapter 3 Installation and Wire Connection 3.1 Mechanical installation 3.1.1 Installation Environment Please mount inside a well-ventilated location. The ambient temperature is required to be within the range of -10 ~40 ℃ . If the temperature is higher than 40 ℃ , the inverter should be derated, at the same time the ventilation and heat dissipation should be enhanced. Be away from the location full of dust or metal powder, and mount in the location free of direct sunlight. Mount in the location free of corrosive gas or combustible gas. Humidity should be lower than 95% with no dew condensation. Mount in the location where vibration is less than 5.9m/s2 （ 0.6G ） .
Please try to keep the inverter away from EMI source and other electronic devices which are sensitive to EMI. 3.1.2 Mounting Space and Direction Generally in vertical way. For the requirements on mounting space and distance, refer to Fig.3-1. When several inverters are installed in one cabinet, they should be mounted in parallel with special incoming and out coming ventilation and special fans. When two inverters are mounted up and down, an air flow diverting plate should be fixed as shown in Fig.3-2 to ensure good heat dissipation. 23
