3.1 Ambient temperature: -5 �~+40 �, average value in 24 hours should not exceed +35 �; 

3.2 Altitude: not exceed 2000m; 

Air conditions: Relative humidity of the air couldn't exceed 50% when the highest temperature is +40 �; 

much higher relative 

humidity is allowable under the condition of lower temperature, for example, when the temperature reaches +20 �, 

the relative 

humidity is up to 90%.As for dews, which contingently appear due to change of temperature, special steps should be taken. 

3.3 Pollution grade: 3; 

3.4 Mounting category: II; 

3.5 The product should be mounted at the site without obvious vibration and keep away from rain and snow; 

3.6 The product should be mounted in medium without rust gas and dust;
