We've decided to put Sinamics S120 in place of these 24 frequency inverters that I have to replace. Do you know if there are problems or incompatibility of Sinamics S120 working in a DC Bus from other manufacturer and in the same busbar of others frequency inverters? Thanks in advantage.

Further the max. for booksize modules is 820V. With fuses you should protect the SINAMICS modules. In catalogue PM21capture 13, page 35.... you will find examples for supply with DC- link adapters https://www.automation.siemens.com/mcms/infocenter/content/de/Seiten/order_form.aspx?nodeKey=key_9174327&infotype=catalogs But I don`t think that you will get an official release from SIEMENS. But if you would take the risk, you can try ... (you can do with your proprietary what you want, but what iswith the guarantee?...) Regards Zako
