Normal Service Conditions

The maximum ambient temperature should be -5°C≤+40°C, average temperature should ≤ 35°C at 24h. The altitude of installation place should not exceed 2000m. The relative humidity should not exceed 50% at 40°C, it permitted higher relative humidity when at higher temperature, the average max mum 90% at maximum humidity month, and this month’s average minimum temperature not exceed +25°C and should take consider of the condensation on the product’s surface for temperature change.
