SRT10kva does not recognize RBC installed

[Mburi]

I encountered the above Ups which according to customer there was a power outage for almost 12hrs, after power restored it went into bypass.When I arrived there almost 3weeks later it was no longer on bypass.This time it was not able to detect RBC installed even if you remove them it keeps showing on the dispay that RBC are in good health.What measures to take to restore it. The RBC have completely discharged.

Hi @Mburi 

Thank you for reaching out to the SE Community, my name is Jon and I will assist you with this query.  Apologies for the late revert, let me share with you FAQ articles that I was able to find to assist you with the issue.

Aside from ensuring that all of the batteries of the UPS and battery backs are connected/reseated properly, we would also need to check that the installation dates were correct and that the firmware of the UPS is up to date.  Keep in mind that when you upgrade the UPS firmware, the battery packs should be attached.

Here are the FAQ articles that I was able to find:

• Smart-UPS SRT UPS Reports: Internal RBC Disconnected or Battery Pack x, RBC y is Disconnected 
• SRT Battery Detection 
• How do I update the firmware of my CSH, SCL, SMC, SMT, SMTL, SMX, SRT, SRTL, XP and XU series Smart-... 

I hope this helps.
