3. Working Condition

• Electrical Symbol
  
• Applicable Condition
   
  • Ambient Usage Temperature and Storage Temperature
    Ambient Usage Temperature: -35⁰C~+70⁰C, Standard Temperature: +30⁰C, correction factor of different ambient usage temperature refer to sheet 1.
    Storage Temperature: -40⁰C~+70⁰C
  • Altitude
    The altitude of the mounting site ≤2000m.
  • Relative Usage Humidity and Relative Storage Humidity
    The relative humidity shouldn’t exceed 50% when the ambient air temperature is +40 degrees, higher humidity can be allowed in lower temperature. For example, the humidity can be 90% when the ambient temperature is +20 degrees. Necessary measures should be acted for the condensation produced by the changed temperature.
