Relais when restoring Grid?

Hello,

I have a 3 phase victron system (MP 5000) that works as expected. When a grid failure is detected there is about a single "click" and the MPs are running offgrid. That seems fine, but what i'm not sure about:

When grid connectivity is restored, the MPs are starting a "Relais-celebration", toggling something with about 20Hz for at least 3-5 seconds.

Is that "normal" behaviour, something like a must-do functionality test of all relais, some sort of "soft-connect" to precharge some capacitors, or is this more an Issue that needs to be looked at?

The multiple clicks of the relays after grid recovery is normal.

iirc there are 4 relays on the input side,
