The ambient air temperature is not higher than +40°C and not lower than -5°C.
2. The elevation of the installation site does not exceed 2000m.
3. Humidity: When the maximum temperature is +40°C, the relative humidity of the air does not exceed 50%, and higher relative humidity may be allowed at lower temperatures, for example, 90% at 20°C. Special measures should be taken for the occasional condensation caused by temperature changes.
4. The pollution level of the surrounding environment is 3.
5. The Electrical Knife Switch shall be installed in a place where there is no significant shaking, shock and vibration and there is no rain and snow. At the same time, there shall be no dangerous medium for explosion at the installation site, and there shall be no gas and dust in the medium that can corrode metal and destroy insulation.
