正常使用環(huán)境 Normal operating environment
◇ 周圍空氣溫度不高于 +40℃，不低于 -5℃。24h 以內(nèi)的平均溫度不得高于 +35℃。
◇ 戶內(nèi)安裝使用，使用地點(diǎn)的海拔高度不得超過 2000m。
◇ 周圍空氣相對(duì)濕度在較高溫度為 +40℃時(shí)不超過 50％，在較低溫度時(shí)允許有較大的相對(duì)濕度。( 例如 +20℃時(shí)為 90％ ) 應(yīng)考慮到由于溫度變化可能會(huì)偶然產(chǎn)生凝露的影響。
◇ 設(shè)備安裝時(shí)與垂直面的傾斜度不超過 5°。
◇ 設(shè)備應(yīng)安裝在無劇烈震動(dòng)和沖擊的地方，以及不足以使電器元件受到腐蝕的場(chǎng)所。
◇ 用戶有特別要求時(shí)與制造廠協(xié)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.
