NS-1250 Occasionally Cycles from Green-Yellow-Green

[Anonymous user]

Lately, I've noticed that my NS-1250 briefly cycles from Green to Yellow (beeps 4 times) and back to Green a few times a day. It doesn't affect the operation of my system - just cycles. Anything I should be concerned about?

Thanks for your help.

Good day,

Here are some of the reasons for a beeping UPS. The unit you have probably detected interference in the supplied input power and switched to on-battery operation momentarily.

Thanks for the information - that makes sense. Hey, at least I know it's doing its job.
