Working conditions
◊ the ambient air temperature shall not be higher than + 40 ° C and not lower than - 5 ° C, and the average temperature within 24 hours shall not be higher than + 35 ℃;
◊ for indoor installation and use, the altitude of the place of use shall not exceed 2000m;
◊ the relative humidity of the surrounding air shall not exceed 50% when the maximum temperature is + 40 ° C. It shall be allowed to have a large relative humidity at a lower temperature (for example, 90% at + 20 ° C), taking into account the impact of occasional condensation due to the change of temperature;
◊ when installing the equipment, the inclination with the vertical plane shall not exceed 5.;
◊ the equipment shall be installed in places without violent vibration and impact, as well as places where it is insufficient to cause corrosion of electrical components;
◊ if users have special requirements, they can negotiate with the manufacturer.
