Hello community, I greet you and ask for your help with the following problem that I have, I was performing maintenance on an 80 KVA Symmetra UPS and the machine after removing a power module and reinserting it began with overload alerts, how rare is that it sent 999% load, remove all the power modules and all the load at the output and continue with that error the machine does not let me put it online, change the current sensors at the output, the communication module, the module of bypass, the control modules and it continues with the failure, I think it must be a wiring issue because the machine is manufactured in 2008, however I would like to know if you have ever had a similar failure or any clue to solve.
