Conditions of Use
• The ambient air temperature is not higher than +40°C and not lower than -5°Co. When the average temperature within 24 hours must not exceed +35°Co, it needs to be derated according to the actual situation.
• For indoor use, the altitude of the place of use must not exceed 2000m.
• The relative humidity of the surrounding air does not exceed 50% when the highest temperature is +40°C, and a larger relative humidity is allowed at lower temperatures, such as 90% at +20°C, and the possibility of temperature changes should be considered Will have the effect of condensation.
• When the device is installed, the inclination to the vertical surface does not exceed 50°C, and the entire group of cabinets is relatively flat (in accordance with the GBJ232-82 standard).
• The device should be installed in a place where there is no violent vibration and impact and not enough to prevent the electrical components from corroding.
