3P 4P |
R:(Normal one, do not mark) automatically changeover and automatically recover S:Automatically changeover and not automatically recover T:two are the backup |
Note: Grid to generator only can select the working mode of automatically changeover and automatically recover.
Remark the ATS mode: grid to grid, grid to generator,in order to set up the parameter when factory out.
● Using environment temperature: ambient temperature: -35℃~+70℃, average value with in 24h does not exceed +35℃.
● Relative humidity: does not exceed 50% when at +40℃,it can has relatively high relative humidity when at low temperature.
● Pollution grade:3
● Height above sea level: does not exceed 5000m
● Electromagnetic environment:A
● Installation category of main circuit: Ⅲ
● Installation category: Ⅲ
● Installation environment: at the places of there is no danger of explosion and conductive dust,not enough to corrode metal and destroy insulation
● Installation angle: In places with no impact vibration and no rain and snow invasion, the inclination of the installation plate and each direction shall not exceed 5°
● The product should put lightly put when transportation, should not be inverted, to avoid violent collision.
