Why is the battery indicator illuminated on my Emerson GXT4-5000RT230 UPS?

If the battery indicator is illuminated on your Emerson UPS, it means the unit is running on battery power. First, ensure the UPS is securely plugged into the wall. If it is, the input protection fuse might have blown. In that case, save your data, close applications, replace the UPS input fuse, and then restart the UPS. Also, the mains power may be out of tolerance. Ensure the mains supply voltage is within acceptable limits for the UPS.
