2.Operation Conditions:

1. Mostly applied outdoor in system of 50Hz and 60Hz

2. Max Altitude is 3500m. Because of high altitude and bad thermal discharging in plateau, please indicate in order if in this situation.

3. Ambient Temp is between -20°C~+70°C and relative humidity does not excess 95%.

4. Wind pressure does not excess 700Mpa (equivalent to 34m/s)

5. Earthquake intensity is less than 8 degree.

6. Thickness of ice coverage is less than 10mm

7. Air dusty grade is not higher than IV grade

8. No corrosive or explosive gas and conductive dust around installation site.

9. As the resistor is a heat generating component, it should be installed in place with some space left around, and be away from heat source.
