Terms of Use
The ambient air temperature shall not exceed 40 ℃, not be lower than -5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃.
Indoor use, use at an altitude of ≤ 2000m.
When the relative humidity of the surrounding air reaches a maximum temperature of+40 ° C, it should not exceed 50%. A higher relative humidity is allowed at lower temperatures, with 90% at+20 ° C. The influence of condensation that may occur accidentally due to temperature changes should be considered.
The device should be installed in a place without severe vibration and impact, and in a place where electrical components are not subjected to undue corrosion.
