New Back-UPS humming

This was originally posted on APC forums on 5/23/2017


Hi,

I've brought a brand new Back-UPS ES 700. It seems to just whine/hum permanantly in the background. I tested it briefly yesterday by turning the AC off, and so it spent the evening charging but making the noise I thought that was the cause of the hum. But even at 100% charge today it's making the same noise. Every 10 or so seconds the humming interupts for a fraction of a second which just makes it more noticeable.

There is load on the master, the surge and some of other UPS-covered ports.

Both LED's are green and powerchute is reporting not problems.

Is this normal? It seems broken to me as it's very noticeable in even a reasonably loud room.

Thanks

Hi,

The UPS may have a slight hum but it should not make enough noise to be bothersome. If the unit is making more noise than you feel is proper you should contact local support. They will assist with a few simple trouble shooting steps and if needed provide a replacement unit. Local support contact information can be found at this link http://www.apc.com/uk/en/support/contact-us/index.jsp

Hi John,

Can you provide the model and serial number of the UPS, this can be located on the bottoms of the UPS.

Regards

How many models are there that are "Back-UPS ES 700"? The Model is "BE-700G UK" I'm uncomfortable sharing serial number on a public forum

Re: New Back-UPS humming

Bought yesterday a new BR1500G-FR and it produces a nerve wrecking humming, louder than my Desktop and 2 NAS combined. I can't have something like this in my office. Will this go away? Is there a solution?

Thanks!
