High Overload and Low Overload
The Inverters have different power ratings for "High Overload" and "Low Overload".
The load characteristics are given below and refer to a duty cycle of 300 s. In case of no
further specification or in the case of rated values, the values always refer to low overload.

Figure 6-1 Duty cycle, High Overload and Low Overload
Note
Please note that 100 % power or current for Low Overload is higher than 100 % 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 using duty
cycles. See section .
