An explosion-proof distribution box can operate reliably under the following conditions:
1. The environmental temperature should not exceed +40°C as the upper limit and should not be lower than -20°C as the lower limit, with a 24-hour average not exceeding +35°C;
2. The installation site should be at an altitude not exceeding 2000 meters;
3. The location should be free from significant oscillation, vibration, and impact;
4. The site should have an average relative humidity below 95% and an average monthly temperature above +25°C;
5. The pollution level should be rated as Grade 3.
When installing an explosion-proof distribution box, factors like installation location, environmental temperature, humidity, external impacts, and vibrations must be taken into consideration.
