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 VFD should be de-rated, 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 90% with no dew condensation.
Mount in the location where vibration is less than 5.9m/s2
（
0.6G
）.
Please try to keep the VFD away from EMI source and other electronic devices
which are sensitive to EMI.
3.2 Mounting Space and Direction

Generally in vertical way.
For the requirements on mounting space and distance, refer to Fig.3-1.
When several VFDs are installed in one cabinet, they should be mounted in
parallel with special incoming and out coming ventilation and special fans.
When two VFDs are mounted up and down, an air flow diverting plate should
be fixed as shown in Fig.3-2 to ensure good heat dissipation.
