Phase sequence wiring on S19 Hydro

[Beny44]

As I wrote in an adjacent thread I'm having problems with chain drops on the PSU. Temperature is out of the question, that's not it. Internet should be fine as well. Last idea is the power supply. There could be a voltage drop in the mains if it is necessary to follow the phase sequence, as with an electric motor?
Tnx
