About the device
In case the mains failure lasts for a longer time, the
batteries will discharge and the UPS will switch off,
before the deep discharge level is reached. In this
very moment the connected loads are also switched
off immediately.
In order to prevent this and an eventual data loss at the
PC, the UPS can be monitored by the PC it is connected
to. See section 7.3.

Remove short-circuit and restart UPS
F02 Overload fault
Disconnect all loads and restart UPS
F03 Battery overcharged
Contact service
F04 Battery fault

F05 Overvoltage on output
Contact service
F06 Overtemperature
Let UPS cool down
7. Handling and operation
The button on the front is used to switch the device on
or off, at mains presence or at mains failure (cold start).
Press the button shortly and firmly, until you can hear
a beep sound. After a short lead time the UPS will be
ready to work.
The display is touch sensitive. It means, the various
values and statuses are cycled through by tapping the
screen. By default, the illumination is turned off. In this
situation either an alarm or tapping the display once will
activate illumination again. Errors acoustically indicat-
ed. There are no further operating elements.
Display in offline operation:
7.1 Normal operation
Normal operation at an UPS means the presence of
mains voltage where the load(s) are supplied by the
UPS via an internal transformer, which is standard at
models with Line Interactive technology. The output
voltage is stabilized in a certain range by a so-called
boost & buck converter. During operation of the UPS
the can display show the measured input voltage, as
well as load level, battery level and output voltage:
(output voltage shown)
7.2 Battery operation (backup)
At a mains failure (mains loss or undervoltage), the
UPS will automatically switch to battery operation,
also called backup mode. Then the consumer(s) are
supplied from the batteries via a voltage converter. The
UPS signalizes this with an acoustic alarm.
Display in battery operation:
After return of the mains supply, the UPS will switch
automatically to normal operation, the batteries are
charged again and the acoustic alarm vanishes. The
recharge time varies depending on the duration of the
former mains failure. Means, the level the batteries
were discharged to.
