Working and Installation Conditions
1. Ambient temperature: -5℃ ~ 40℃; and the average temperature in 24 hours should be ≤35℃.
2. Elevation: ≤2000m
3. The relative humidity should be no more than 50% at the maximum ambient temperature of 40℃, while it could be relative higher when the ambient temperature is relatively lower. In the month with the highest relative humidity, the minimum average temperature should be no more than 25℃m, and meanwhile, the month's maximum average relative humidity should be no more than 90%. Special measures should be taken to avoid or remove condensation caused by temperature changes.
Relative humidity: ≤ 50% (at the maximum ambient temperature +40℃); Special measures should be taken to avoid or remove condensation caused by temperature changes.
4. The AC contactor should be installed on steady surfaces without shaking or vibration.
5. Installation method: screw mounting
6. Installation class: class III
7. Pollution grade: Grade: 3

Usage Instructions
In operation, the switch contactor's silver contacts may become black or seem like being burned due to frequent switching on and off. This phenomenon is normal. Please don't need to polish the contacts if it doesn't affect normal work. Or else, the silver contacts' lifespan may be reduced. When the blacking or burning phenomenon is serious and influences normal work of the AC contactor, users can slightly polish the contact surface using a nail file, and the silver contacts can serve for work before exposing of the contact plate.
