power switch

[Anonymous user]

Hi,
I just purchased a XS1300 ups and noticed that the Power on/off and Display switches are always lit even when unit is off. Is this normal?
Thanks

Yes, this is normal.

The unit itself and the buttons are all black, therefore the only way you'd be able to see the Power button when the lights are out is if it is illuminated.

Thank you, for your quick response. But this leads to another question.
How do you tell which state the ups is in? Other devices have lights that indicate on/off, including computers (black), monitors (black) and my old ups. There is no problem finding these switches unless one operates in the dark.

This would all depend on how you have the UPS setup. If the LCD display dims out after a period of time to conserve power (user-defined setting), it would look the same as if the UPS were off. I think the key here is that once the UPS is turned on, it's not designed to be used as a on/off device. It should be on continuously so that there is no battery degradation.

I understand now, it's the LCD that is the on/off indicator. You mentioned battery degradation, is not the battery still being charged when in the off position? are you referring to the quality of the input power?
Thanks for your patience!

Moreso pertaining to powering off and then back on the UPS. It will charge when the UPS is off, but every time you turn the UPS on, it's using the battery, also using the inverter, rectifier and transfer switch. Degradation of these parts would be larger than every 2 weeks when the UPS runs a self-test because of turning the UPS on and off daily, or more than 1x daily.
