Functions and Features

◆The ambient air temperature should not be higher than +40℃ and not lower than -5℃. The average temperature within 24h shall not be higher than +35℃.
◆Indoor installation and use, the altitude of the place of use shall not exceed 2000m.
◆The relative humidity of the surrounding air does not exceed 50% when the maximum temperature is +40℃, and a relatively large relative humidity is allowed when the temperature is lower. (eg 90% at +20°C) The effect of condensation that may occasionally occur due to temperature changes should be considered.
◆When the equipment is installed, the inclination from the vertical plane should not exceed 5%.
◆The equipment should be installed in a place without severe vibration and shock, and a place that is not enough to cause corrosion of electrical components.
◆When users have special requirements, negotiate with the manufacturer.
