*) If the battery is disconnected for over 30 minutes, the BAT diode will remain lit steadily.
Check whether the GEN FLT fault indication has been transmitted correctly during the tests.
Caution
do not connect the negative pole of the battery (B) to the negative pole OUT1 OUT2 (-).
When mains power is being supplied, the battery voltage is over 21.6 V.
The Warning indication (brief flashes of the ALARM LED) is displayed with intermediate voltages.
In battery operating mode, when there is no primary (230 V) power supply and the value drops below 21 V, the LVDD (Low
Voltage Disconnect Device) disconnects the battery to avoid damaging it.
