正常使用環境 Normal operating environment

◇周圍空氣溫度不高于 +40℃，不低于 -5℃。24h 以內的平均溫度不得高于 +35℃。 

◇戶內安裝使用，使用地點的海拔高度不得超過 2000m。 

◇周圍空氣相對濕度在溫度為 +40℃時不超過 50％，在較低溫度時允許有較大的相對濕度。( 例如 +20℃時為 90％ ) 應考慮到由于溫度變化可能會偶然產生凝露的影響。 

◇設備安裝時與垂直面的傾斜度不超過 5°。 

◇設備應安裝在無劇烈震動和沖擊的地方，以及不足以使電器元件受到腐蝕的場所。 

◇用戶有特別要求時與制造廠協商解決。 

◇ Ambient air temperature is not higher than +40℃ and not lower than -5℃ . The average temperature within 24 hours shall not be higher than+35℃ . 

◇ For indoor installation and use, the altitude of the place of use shall not exceed 2000m m. 

◇ The relative humidity of ambient air shall not exceed 50% at the highest temperature of +40℃ , and a larger relative humidity is allowed at the lower temperature. (for example, 90% at +20℃ ) consideration should be given to the effect that condensation may occasionally occur due to temperature changes. 

◇ When the equipment is installed, the inclination to the vertical plane shall not exceed 5. 

◇ The equipment shall be installed in places free from severe vibration and impact, and places insufficient to corrode electrical components. 

◇ When users have special requirements, negotiate with the manufacturer to solve them.
