| Operating Conditions Ambient air temperature Limit of temperature: -5ºC~+40ºC. The average no more than +35ºC within 24 les heures. Transportation and storage Limit of temperature: -25ºC~+60ºC, The temperature can be up to +70ºC within 24 les heures. Altitude ≤ 2000m Atmospheric condition When the temperature is +40ºC, the air relative humidity should not exceed 50%, only under lower temperature can allow for higher relative humidity. If the temperature is 20ºC, the air relative humidity could up to 90%, Special measures should be taken for occasional condensation due to humidity changes.
