This event may be caused by a blown charger fuse, or bad batteries.
To determine the cause of this behavior, perform the following troubleshooting steps:
  • With the UPS input connected to AC mains, disconnect all the batteries in the system: all internal batteries and any external batteries, if used.
  • Go to the Status section on the display and under Battery, check Voltage.
Note: You do not need to perform measurements on the UPS battery terminals.
  • If the voltage displayed on the UPS display is below the “Voltage level” (refer to the below values), the charger fuse is blown and the UPS requires replacement.
