afaik all you need is a phase coupler - marmitek.nl might have some.
I the manual it mentions:
If the power line system in your home is 3-phaes, you need to adjust your #4034E to "3-phase" status. That means before you use your #4034E, you need to confirm which status your #4034E is between "1-phase" and "3-phase".
I suppose that status influences the way it functions.
