Applying Ambient Conditions
1. The ambient air temperature is not higher than +40°C, not lower than -10°C; 2. The altitude of the installation site should not exceed 1000 meters for the ordinary type and 4000 meters for the plateau type; 3. The relative humidity of the air, the monthly average maximum relative humidity of the wettest month is 90%, the monthly average minimum temperature of the month is 25C, and the condensation on the product surface due to humidity changes is considered; 4. There is no obvious shaking and shock vibration occasions. 5. In a place without explosion hazard, and there is no gas and dust (including conductive dust) sufficient to corrode insulation; 6. Places without rain and snow.
