CAUTION! In figure set of contacts shows a potential-free status of relay, which corresponds to power supply
failure.
3.3 Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an appropriate
standby time, Required battery capacity can be calculated using following formula:
Q
AKU
= Standby Period*(I
WY
+ Iz)
where:
Q
AKU
– minimum battery capacity [Ah]
I
WY
– power supplies output current (drawing by the load)
Iz – PSU current consumption (including optional modules) [A] (Table 3)
Total current of the receivers + battery charging current mustn’t cross maximum current of power supply.
3.4 Battery charging time.
The PSU has a battery circuit charged with direct current. The current selection is done with use of the I
BAT
jumpers. The table below shows how long does it take to charge a (fully discharged) battery up to min. 80% of its nominal
capacity.

3.5 Running PSU on battery backup.
Power supply allows you to run on battery backup when necessary. To do this, press the START button on PCB.
4. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the power
supply network. The PSU does not require performing any specific maintenance measures, however, in the case of
significant dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse replacement,
use a replacement of the same parameters.
WEEE LABEL
Waste electrical and electronic equipment must not be disposed of with normal household waste.
According to the European Union WEEE Directive, waste electrical and electronic equipment should
be disposed of separately from normal household waste.
CAUTION! The power supply unit is adapted for cooperation with the sealed lead-acid batteries (SLA). After the operation period they must
not be thrown but recycled according to the applicable law.
