Inverter Gird Parameter Setting: Frequency Protection - Kaco blueplanet 25.0 NX3 M3 Manual

2.2.6 Inverter gird parameter setting: frequency protection

Tap 'Grid Frequency Protection, the next page will display the parameter.
There are three threshold level for the over-frequency and underfrequency protection. The first threshold means the
smallest range, and the third threshold means the largest range.
All thresholds need to follow the principles as below:
1. The first maximum threshold ≤ The second maximum threshold ≤ The third maximum threshold
2. The first minimum threshold ≥ The second minimum threshold ≥ The third minimum threshold
3. The first threshold tripping time ≤ The second threshold tripping time ≤ The third threshold tripping time
