It is always critical to keep the device in the charging more for several hours
(min. 8 hrs.) to achieve the complete charging status of the accumulator before
the device can assume its proper support function.
6.1.3 Autonomous mode of the UPS
✓ The device is in standard operating mode (6.1.2).
In the event of a power failure, the UPS
immediately switches to the autonomous
mode. This situation can be simulated by
interrupting the power supply to the
device.
The display pictured here appears and
directly indicates the autonomous mode
via the battery symbol. In the example
here, the still present output voltage is
indicated.
The autonomous mode is further sup-
ported by a repeating acoustic signal.
The rhythm depends on the charging
status.
The UPS output remains on; the loads continue to be supported for the duration
of the autonomous period.
Through restoring the network connection, the UPS automatically returns to the
standard operating mode / charging mode.
6.1.4 Switching the UPS off in the STANDBY mode
✓ The device is in standard operating mode (6.1.2).
