MetaSystem Top line HF 950

MetaSystem Top line HF 950

(OP)
I have a problem with UPS Metasystem Top line HF 950, i have changed all power amplifier boards but Protection LED still lighted red and sound alarm is beeping.
I think that I need some software for canceling that error. Can somebody help me?

RE: MetaSystem Top line HF 950

Have you checked your mains voltage ?  It could be out of tolerance, either high or low. Chances are the alarm is trying to tell you something, you need to figure out what is out of tolerance. How big a load have you put on the unit ? Could the warning be telling you that if you had to go on battery, you'd be exceeding the capability ?
