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.
