Conditions of Use

Ambient air temperature: (a) The ambient air temperature is limited to +40 ° C, the average value of 24 h does not exceed +35 ° C; (b) The lower limit of ambient air temperature is –5 ° C.

Altitude: The altitude of the installation site is generally not more than 2000m.

Atmospheric conditions: The relative humidity of the air at the installation site does not exceed 50% at a maximum temperature of +40 ° C; higher relative humidity is allowed at lower temperatures, and the monthly minimum temperature of the wettest month does not exceed +25 ° C. The monthly average maximum relative humidity for the month does not exceed 90%. Measures must be taken due to condensation on the product due to temperature changes.
