Description of Functions
F1319
Functions corresponding to high altitude areas
In high altitude areas, due to the unit cooling capacity, the current derating rate of parts and other reasons, it is
recommended to use larger inverters by one rank
.
However, when used in high-altitude areas of more than 1,000m above
sea level, the rated current can be derated, and this function should be used for selecting suitable altitude where
applicable.
