The PSU has a battery circuit charged with direct current. The current selection is done via
I
BAT
jumpers.
The table below shows how long it takes to charge a (fully discharged) battery up to min. 80% of its nominal
capacity.

4.6 Operation without a battery.
In case of an expected PSU operation without an attached battery, make a necessary configuration setting
from the level of the LCD desktop (see chapter 3.4.2, table 7).
”Settings -> PSU -> Battery present: YES/NO”
In this mode the automation system allows adjustments of PSU’s output voltage without indicating a failure
connected with working of the battery.
CAUTION. During operation without battery assistance the PSU does not perform any parameter
control that monitors its proper operation. Therefore, this mode ought to be chosen thoughtfully.
