Hello Ajiajesh; In the case specifically of the AC power supplies developed for the S7-300 (PS 307) and the S7-400 (PS 407), considerations for grounding include the complete rack (PS, CPU, CP and I/O modules). These details are discussed in the Installation Manuals of the resective CPU families: SIMATIC S7-300 CPU 31xC and CPU 31x: Installation https://support.industry.siemens.com/cs/us/en/view/13008499 S7-400 and M7-400 Programmable Controllers Hardware and Installation https://support.industry.siemens.com/cs/us/en/view/19537233 The Sitop power supplies are a bit different, in that they are not designed specifically for PLCs, and can be used to supply any electronic system that accepts its power output. You should install them as required by your system design. SITOP PSU100S manual https://support.industry.siemens.com/cs/us/en/view/67476474 Hope this helps, Daniel Chartier |

Your grounding is floating at the moment, if you get that high voltage measurements against ground. |
