Battery Operation / Autonomy Operation

Mains
Diagram
The mains is not within the required tolerance range or has
failed. In this case power is supplied to the inverter from the
charged battery without interruption. The power supply to the
loads is therefore also ensured in the event of a mains failure.
This drains the capacity of the battery and it is discharged. This
status is signalled by the battery symbol (LED BATTERY)
lighting up, as well as an intermittent acoustic signal every 4
seconds and every second before switching off. This can be
suppressed by pressing the "ALARM OFF" button. With
decreasing battery capacity the alarm is activated automatically.
Depending on the expansion level, age and condition of the
battery and in particular on the load to be supplied, the standby
time can vary from a few minutes to several hours.
The LED bargraph (LED chain on the left hand side of the ON
/ OFF button) show during operation the actual utilization of
the UPS (s. page 38 ff).
The inverter is switched off if the battery voltage drops below
a factory-set minimum voltage value.
Never store the unit in this condition! The discharged battery
system should be recharged within a week at the latest.
When the voltage and frequency are within the tolerance
range once more, the rectifier and the battery charger switch
back on automatically. The rectifier then continues supplying
the inverter and the battery charger takes over charging the
battery.
