How to set Input Current Limit for 2 Split-Phase Quattros

I have two Quattro 48/5000/70's running split-phase 120/240, grid-tied. A Cerbo GX controls them and gives me access to Remote Console via a LAN connection.

Right now, L1 feeds a 60A breaker that feeds Quattro#1. L2 feeds another 60A breaker that feeds Quattro #2.

In Remote Console, Quattros > Input Current Limit, how should I set it? 60A or 120A or something else?

In other words, in Remote Console, are my input current settings for each Quattro or a sum of both?

Thanks to this forum for being such a great resource!

The Circuit breakers need to be rated at about 120% of the expected continuous current, so for 60A breakers you need to limit the phase current to 50A. Input current limit programmed is per phase, so would be programmed at 50A.
