◇ 設(shè)備安裝時(shí)與垂直面的傾斜度不超過(guò) 5°。 

◇ 設(shè)備應(yīng)安裝在無(wú)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.
