Matters needing attention

 ● The ambient air temperature shall not exceed +70 ° C, not lower than -25 ° C, and the average temperature value within 24h shall not exceed +35 ° C.   ● The elevation of the installation site does not exceed 2000m.  
 ● Humidity: When the maximum temperature is +60 ° C, the relative humidity of the air does not exceed 95%, and special measures should be taken for condensation occasionally caused by temperature changes.   ● The ambient pollution level is level 3.  
  ● The switch should be installed in a place where there is no significant shaking, shock shock and no rain or snow attack, and the installation site should be free from explosive dangerous media, and there is no gas and dust in the media that is enough to corrode metal and destroy insulation.
