2. Model and meaning
3.Conditions of Use
>The ambient air temperature should not be higher than +40°C and lower than -5°C. The average temperature over a 24-hour period should not be +35°C. If it is higher than this, it should be operated at a reduced capacity according to the actual conditions. If it exceeds the average temperature of 24 hours, it should be operated with reduced capacity according to the actual situation.
>For indoor use, the altitude of the place of use shall not exceed 2000m.
>Relative humidity of the surrounding air shall not exceed 50% when the maximum temperature is +40℃, and it is allowed to have a larger relative humidity when the temperature is lower, such as 90% when it is +20℃, and it shall be taken into account that condensation may occur due to the change of temperature.
>The inclination of the device to the vertical plane when it is installed shall not exceed 50℃ and the whole group of cabinets is relatively level. (in accordance with GBJ232-82 standard).
>The device should be installed in a place where there is no violent vibration and shock and where the electrical components are not subject to due corrosion.
