Battery Operation / Autonomous Operation - AEG Protect A. 1000 Operating Instructions Manual

The connected loads are powered using the monitored and
filtered mains voltage, which is additionally stabilised by the
integrated A.V.R. control unit. The "LINE MODE" symbol
shows that the unit is active.

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 batteries. This drains the capacity of the
batteries and they are discharged. This status is signalled by
the battery symbol flashing as well as an intermittent acoustic
signal (chapter 4.3 / no. 2 / pg. 19).
If the UPS does not automatically return to normal operation
after a few minutes, close all your work as usual and switch off
the loads (e.g. PC) before the batteries are fully discharged.
This lengthens the service life of the batteries! Switch OFF the
UPS by pressing the main switch.
During the discharge process as the battery capacity
consistently drops, the battery symbol flashes, accompanied
by an intermittent acoustic signal (once every 10 seconds).
The electronics of the UPS switch off the voltage supply of the
loads shortly after the battery undervoltage limit is reached
(the battery logo above the battery voltage display also
flashes; acoustic signal sounds every second).
Never store the unit in this condition! The discharged battery
system should be recharged within a week at the latest.
When the mains voltage comes back, the UPS must be
switched on again using the main switch (only applies if it was
previously switched off manually), in order to recharge the
battery and thus store sufficient battery capacity for any
possible future mains failures.
The batteries are automatically charged when the mains is
present. The battery charging time (to 90% of rated capacity)
is about 6 hours after being previously fully discharged.
