because the cooling effect of inverter is deteriorated because of the thin air. Derating 6% per 1000 m higher of
the altitude.
2.2.2 Ambient Temperature
In order to enhance operating reliability of the inverter, be sure where the inverter mounted has a good ventilation;
when the inverter is used in a closed case, cooling fans or an air-conditioning must be installed to keep the ambient
temperature below 40℃
2.2.3 Preventive Measures
Installing the inverter, please set a shield to prevent metal debris falling into it, and remove the shield after installing.
Please remove the protection membrane when the ambient temperature is over 40° C or the internal temperature is
too high due to other reasons. Please pay attention to avoid small parts falling into the inverter.
2.3 Installation Direction and Space
Inverters of this series are all equipped fans for forced cooling. In order to be an effective cooling cycle, the inverter
must be mounted in the vertical direction, up, down, left and right away from adjacent articles or baffle (wall)
maintain adequate space, as Figure 2-1
