Yes and no, the adapter is only suitable for fixed installations to a limited extent. Namely, only if the unit does not run continuously and does not draw much current:
On the back of the packaging it says "It may only be operated for one hour within 6 hours with the rated current I and the maximum power P" (10A/2500W).
Furthermore, the adapter is not "fixed" in the sense of "no longer removable".

In principle, yes;
However, with a triple socket, the 2 remaining connections are no longer sufficiently accessible!
