1. General
Electric ratings: AC50/60Hz, AC220V/DC220V; Degree of protection: IP40; Standard: IEC/EN60947-5-1
2. Operating conditions
2.1 Ambient temperature is -5℃~+40℃, the average temperature during 24 hours couldn't exceed +35℃.
2.2 Altitude: ≤2000m.
2.3 Atmosphere condition: Relative humidity of the atmosphere couldn't exceed 50% when the highest temperature is +40℃; much higher relative humidity is allowable under the condition of lower temperature, for example, when the temperature reaches +20℃, the relative humidity is up to 90%. As for dews, which contingently appear due to change of temperature, special steps should be taken.
2.4 Pollution degree: 3
2.5 Overvoltage category: Ⅱ
