Table 13:
Electrical data of the inverter modules
1)
The protection functions are designed for rated operation with 8 kHz.
2)
The output frequency is to be limited in such a way that it does not exceed 1/10 of the switching frequency.
Units with higher max. output frequency are subject to export restrictions and are only available on request.
