Permissible inverter overload
The inverters have different load capabilities, "High Overload" and "Low Overload",
depending on the expected.
Figure 6-2
Note
Please note the base load (100 % power or current) for Low Overload is higher than the
base load for High Overload.
The load characteristics shown in the diagram are only examples. We recommend the use of
the "SIZER" engineering software to select the appropriate Power Modules based on the
load situation. See Configuring support (Page 88).
