3. Operation conditions
1. Ambient temperature: the maximum temperature is +40℃ and the lowest temperature is -5℃. The average temperature in 24 hours should be less than +35℃.
2. The relative humidity of ambient air should be less than 50% when the highest temperature is +40℃. The higher relative humidity is allowed at lower temperature, for example, when temperature is +20℃, the relative humidity can be 90%. Dewing may happen accidently due to the change of temperature.
3. Altitude should be less than 2000m.
4. Earthquake magnitude should be less than 8.
5. The place should be free from serious contamination, chemical corrosion and strong vibration.
6. If the users have special requirements, coordinate with manufacturer.
4. Ordering Instruction
Orderer should offer the following technical document:
1. All types of products include main circuit plan No. and auxiliary circuit plan No.
