Rotary Switch Wiring Diagram
Working Conditions
1. The ambient air temperature ≤ +40 ° C, and the average temperature within 24 h ≤ +35 ° C.
2. The lower limit of ambient air temperature ≤ -25 °C.
3. The altitude of the installation location is ≤2000m.
4. When the maximum temperature is +40 °C, the relative humidity of the air does not exceed 50%, and the higher relative humidity can be allowed at lower temperatures, for example, 90% at 20 °C. Special measures should be taken for condensation that occasionally occurs due to temperature changes.
