13.2
High Overload and Low Overload
Permissible inverter overload
The inverter has two different power data: "Low Overload" (LO) and "High Overload" (HO),
depending on the expected load.
Figure 13-1
Note
The base load (100% power or current) of "Low Overload" is greater than the base load of
"High Overload".
We recommend the "SIZER" engineering software to select the inverter based on duty
cycles. See Configuring support (Page 341).

If the power data comprise rated values without any further specifications they always refer
to an overload capability corresponding to Low Overload.
