■Product Overview
■Model Meaning
■Operating Conditions
Ambient air temperature not higher than +40°C, not lower than -5°C, and the average temperature within 24 hours not higher than +35°C. If exceeded, derating operation is required according to the actual situation;
Indoor use, the altitude of the installation site shall not exceed 2000m;
Relative humidity of ambient air does not exceed 50% at the highest temperature of +40°C. At lower temperatures, higher relative humidity is allowed, such as 90% at +20°C. Consideration should be given to the possible occasional formation of condensation due to temperature changes;
The inclination of the device installation to the vertical plane does not exceed 5°, and the entire group of cabinets is relatively flat (complying with GBJ232-82 standard);
The device should be installed in places without severe vibration and impact, and where electrical components are not subject to corrosive damage;
Special requirements from users can be resolved through consultation with the manufacturer.
