Hello "how come?" Could you be a little more detailed in your question? You are posting in the "other Process Control Systems" folder; which system are you working on? Without more information, I would guess your question related to differnt ground connections required for EMC protection of your CPU rack (PE being "Protective Earthing"), especially since you are asking about connecting IE and PE together (shielding and Protective Earth?). If that is the case, you could look at the following manual on EMC installation guiidelines; it is for Sinumerik units (CNC controllers), but it covers a lot of the principles involved in protecting electronic units in the field. Hope you find it as informative as I did when I read it. http://support.automation.siemens.com/WW/view/en/28518276 If the matter refers to anything else, please try to explain your requirements qith a little more details. Hope this helps, Daniel Chartier |
