4. Working and the installing condition
4.1 Ambient max temperature is no more than +40℃, minimum temperature is not less than -5℃. No more than +35℃ within 24 hours;
4.2 Altitude is no more than 2000m;
4.3 When the highest temperature reaches 40℃ the air relative humidity of the installing place can't exceed 50%, when in the low temperature it will have the relative higher humidity. When the average largest relative humidity in the most humiddest it is month no more than 90%, then the monthly-average temperature is no more than 25℃. We must take measure of the dew in the surface of the product due to the temperature;
4.4 Installation conditions: Any direction of the outer magnetic field of the installation site should not exceed 5 times than earth's magnetic field; residual current operated circuit breaker should be mounted vertically, all places inclination no more than 5 °,power position above the handle , the installation place should be no significant impact and vibration.
