Hi Ivan,

For us to answer your query, it is best to provide us the exact UPS model of your APC750 UPS. At the back, there is a barcode sticker where the model and serial number is located. This is to help us identify what the flashing red light means.

Aside from this, I would also appreciate if you can provide the type of load that you are using with the APC750 UPS (including its power rating). One possibility of the red light being present is an overload alarm if the load attached on the UPS exceeds its rating.

I hope this helps. Please let me know if you need any clarification, by replying to this thread.
