Trip Frequency Settings
Note:
There are three thresholds for over-
and underfrequency protection. The first
threshold value specifies the lower range. The
middle threshold range is freely adjustable.
The third threshold value indicates the upper
range.
Open menu <Setting for>.
1. Select <Trip Frequency Settings>
2.
Set thresholds in accordance with the
following principles.
Principle:
-
First maximum threshold ≤ sec
ond
maximum threshold
≤
third
maximum threshold
-
First minimum threshold ≥
second minimum threshold ≥
third minimum threshold
-
Trigger time for the first threshold ≤
trigger time for the second
threshold ≤ trigger time for the
third threshold

Connection Time Settings
Note:
Set monitoring time when one of the
voltage and frequency values has been
changed. If the measured values are within
the range defined by the selected grid
standard, the inverter can start or reconnect
Open menu <Setting for>.
1.
Select <Connection Time Settings>.
2. Define <Start connection time> for
restart.
3. Define <Reconnect time> for
reconnection time.
4. <Confirm> all settings.
