Smart-UPS RT 5000 XL - Critical Alarm

[Anonymous user]

Good morning,

I came into work today and one of my 2 battery backups are throwing a Critical Alarm.
I am not really sure why - I am very new to dealing with battery backups and I have the power features on this backup the same as the other one and it is not throwing errors.

If anyone can explain to me why this is happening and how I should go about fixing it that would be awesome.
I have done a few Google searches, but I have not been able to find anything that I think is what I am looking for in this scenario.

Thank you!

Hi Chuck

Looking at the information you've included it simply is that your utility voltage is coming in at nearly 250 V and you have an output voltage of 208 V so it is information you that the UPS wouldn't be able to go to bypass (supply the load straight from utitlity power bypassing the UPS) because of this.

Thank you, Matt!

If I changed my output voltage on my UPS to 240V then, in theory, I should be fine right?

Hi Chuck

If your load can handle 240 V then setting the output to 240v will definitely help.  You may still see this message at times as a 10v difference between input and output is around the threshold but it will definitely reduce the message compared to the output being set to 208 V.
