Solution
If the charger is overvoltage, the UPS will shutdown. If the
charger is undervoltage and the batteries are nearly depleted,
this alarm will give a temporary warning before the UPS shuts
down. UPS requires service. Contact your local dealer, Liebert
representative or Liebert Worldwide Support Group.
Check battery connections, completely power down and restart
UPS.
NOTE: If the battery circuit
opens while the UPS is running,
it will be detected when the next
battery test is performed.
