Environmental Conditions

• The ambient air temperature shall not be higher than +40 ° C, not lower than -5 ° C, and the average temperature within 24 hours shall  not be higher than +35 ° C;

• For indoor installation and use, the altitude of the use place shall not exceed 2000m;

• The relative humidity of the surrounding air should not exceed 50% at the maximum temperature of +40℃, and a larger relative humidity  should be allowed at a lower temperature (such as 90% at +20℃), considering that the effect of condensation may occur occasionally due  to changes in temperature;

• The inclination between the equipment and the vertical plane shall not exceed 5°;

• The equipment should be installed in a place without violent vibration and impact, and not enough to corrode the electrical components;

• Users have special requirements can be negotiated with the manufacturer to solve.
