Output
The battery will be disconnected if the AC is off and the battery voltage falls below this
10/20.2V
threshold. Reconnection will occur only once AC power is restored.
A successful battery test will result in the Red LED flashing on and off every second during the
11.50V
2-minute test. If the LED emits 5 rapid flashes followed by a 1-second pause, this indicates a
23.0V
battery failure, and the battery should be replaced.
Should the output voltage fall below this threshold, a 'Low Voltage Warning' will be
11.40V
22.80V
triggered. For more details, refer to the Fault Conditions and Indication table.
