Working Condition
1.Ambient temperature should not be more than -25℃ but not less than 40℃; 24-hour average temperature should not be more than +35℃.
2.The altitude of installation site should not exceed 2000m in the case of indoor installation;
3.The relative humidity of ambient air should not exceed 50% at +40℃; a higher relative humidity is allowed under conditions of low temperature (e.g. 90% at +20℃). The condensation may be generated under the influence of temperature variation, which should be taken into consideration.
4.The vertical inclination of equipment should not exceed 5°.
5.The equipment should be installed in the places without violent vibration and impulse and as well the places without corrosion to the electric components
