Operation

Once you have connected the UPS to a suitable mains
connection, you can start operation using the UPS main
switch.
On and Off switch

Normally, the UPS operates continuously. The UPS now supplies
the output with voltage, this being signaled by the green LED
LINE MODE which lights up permanently (pos. 7 p. 42).
5.5.1

Normal Operation

During normal operation, i.e. when mains voltage is available,
the built-in battery charger keeps the battery fully charged and
the mains voltage monitoring system switches the inverter to
standby mode.
The connected loads are powered using the monitored and
filtered mains voltage, which is additionally stabilised by the
integrated AVR control unit.
The UPS capacity utilisation can be read off the bar chart of
the operating panel (pos. 9, fig. p. 42).
5.5.2

Battery Operation / Autonomous Operation

When there is a mains failure or if the input voltage moves
outside the tolerance range, the inverter automatically
switches over to autonomous mode and supplies the loads
with voltage from the battery. This drains the capacity of the
battery and it is discharged. This status is signalled by the
yellow LED BAT.MODE flashing as well as an intermittent
acoustic signal (s. p. 42)
