Ambient conditions

1, For the normal design, the  altitude should be not more than 1,000m. If  above 1,000m, it will design  according to the  altitude correction factor  of the  highland and manufacture as per the requirements suitable for the highland altitude.

2, The ambient  air temperature  ranges -35℃~+40℃, and  the average  temperature within 24h ≤ +35℃. If  exceeding the specified time, it  has to reduce the capacity  according to the actual condition;

3, The relative  humidity  should not  exceed 50%  at +40℃,  while  at lower  temperatures, larger  relative humidity  is acceptable,  e.g.  90% at  +20℃.  Considering the  change  of temperature may sometime cause the condensation, the daily average should be less than 95% and the monthly average less than 90%;

4, The  water  vapour   average  should  be ave2.2*10-3Mpa  or  below   while  the  monthlyrage not larger than  1.8*10-3Mpa;

5, The gradient between installation surface and vertical plane is ≤ 5°;

6, The seismic intensity should be not more than 8 degree;

7, Frequent severe violation is acceptable;

8, No pollution is  allowed to the ambient  air, such as corrosive  substance, flammable gas, vapour and so on.
