Question about Liebert PowerSure ProActive PSA700 UPS System
I have a Liebert PSA itON 600 UPS and when i switched it on it keeps beeping even if not connected to a power supply. Please help...
To figure out what's wrong with the UPS, first you have to do a few things.
When calculating the rating a UPS can handle, it's voltage x amperage. If it's Watts multiply the number by 1.67 to give the rating of the device.
Add up all the devices (use the power supply rating in the computer) as well as any other device, and add them up.
If this rating was exceeded, then you have overloaded the UPS. If it was too long that you did this, then you wore out the battery.
When a UPS beeps even when not connected, that means the battery is very weak.
If the battery is more than 3 years old, it will need to be changed. If the online tests of the unit were done and the battery doesn't need replacing, then other parts of the UPS need fixing.
Check the battery.
