◎   Ambient air temperature: The ambient air temperature is not higher than +70° C, not lower than -5° C, the average value of 24 hours is not more than +35° C, and the FAFDD arc fault protection circuit breaker used in the ambient air temperature is higher than +70 C or lower than -35C should be negotiated with the manufacturer

◎   Sea level: The sea level of the installation site does not exceed 2000m

◎   Atmospheric conditions: the  relative  humidity of the atmosphere does not exceed 50% when the maximum temperature around +60'C, and can have a higher relative humidity at a lower temperature, such as 90% at 20C, for condensation occasionally caused by temperature changes, protective measures should be taken

◎   Installation conditions: The external magnetic field near the installation site of the arc fault protector should not exceed 5 times of the earth magnetic field in any direction; The installation position should be vertical, and the inclination of each direction should not exceed 10%; Installed in a place without shock vibration and without rain and snow attack; Standard TH35-7.5 steel mounting rail is adopted for installation

◎   Pollution level: Level 2

◎   Installation category: Class III

◎   Protection level :IP20(installed in the distribution box, distribution cabinet or box IP40) with N pole products, wiring, must be connected to the neutral line marked with N pole
