Hello, my name is Diego, I am writing in this forum because I am having problems finding the data sheet for a Siemens SINVERT inverter (which later became a refusol inverter), the issue is that my part number appears as REFU 0030457 DP 50Y1200 101953, however, I have not been able to find the data sheet, I don't know if anyone has it or could give me directions on how to find it, thank you very much.
