Hello,

I've got a problem with DC-USV-Modul 15. LED 'Alarm' indicator flashes within 2 sec interval which means it is "Battery not ready" error. Module is connected with 6EP1935-6MF01 battery pack. I've swapped to new batteries in battery block with identical specifications but error doesn't come off. Does this mean that DC-USV-Modul is defective and I need to replace it?

I've added a picture of the module current situation.

Split from DC-USV-Modul 15.
