Some updates... that scary "spider web" wiring is no longer live, just old wires dangling around.
And two days ago the elevator stopped working for some reason. Went up to the 4th floor and refused to come down again. I assume the problem lies next to the door, there are sensors that tell the controls whether the doors are closed or not and probably they quit working.
While checking into it I found three out of the five fuses that beast is running on are jumpered with strands of copper wire though...
There are 2 6 Amp fuses for the lights (hot and neutral, both jumpered) and 3 20 Amp fuses for the 3ph motor (once 380V, now 400), one of which has been "repaired".
