SINAMICS G180转换器和相关系统
components are rated for an ambient temperature of 40 °C
and installation altitudes up to 1000 m above sea level.
在> 40°C的环境温度下,输出电流必须

在安装高度>海拔1000米,必须是
taken into account that the air pressure, and therefore air density,
随着高度的增加而降低。因此,
cooling efficiency and the insulation capacity of the air also
减少。
Due to the reduced cooling efficiency, it is necessary, on the one
hand, to reduce the ambient temperature, and on the other
hand, to lower heat loss in the compact unit by reducing the out-

The values apply under the precondition that a cooling air flow
through the units is ensured as stated in the technical data.
