Model meaning
Operating conditions
1. The ambient air temperature should not be higher than +40°C, not lower than -5°C, and the average temperature within 24 hours should not be higher than +35°C. When it exceeds, the derating operation shall be performed according to the actual situation;
2. For indoor use, the altitude of the site of use shall not exceed 2000m;
3. The relative humidity of the surrounding air does not exceed 50% when the maximum temperature is +40°C, and a larger relative humidity is allowed at lower temperatures, such as 90% at +20°C, which should be considered due to temperature changes. Accidental effects of condensation;
4. When the device is installed, the inclination from the vertical plane should not exceed 5, and the entire group of cabinets should be relatively flat (in line with GBJ232-82 standard);
5. The device should be installed in a place without severe vibration and shock and not enough to cause the electrical components to be corroded;
6. When users have special requirements, they can negotiate with the manufacturer.
