Hy, we forgot to connect the earth to a masterdrive rectifier (50kw, 120A, +integrated brake chopper, Siemens, 6SE7 031-2EP85-0AA0). It worked for several months, then last week the power board was damaged, and it caused fault f002 on all the masterdrive inverters connected to it. Could this be caused by the non-connection of the earth? Thank you …
