In case of power failure, a battery back-up is activated immediately. Power supply is placed in ABS
(IP44) enclosure, which can accommodate a 17Ah/12V (SLA) battery. Enclosure is equipped with a tamper switch
signaling opening the door (front panel).
PSU module should be configured properly, depending on application, to work in burglary and
assault signalling systems or access control. For this purpose, appropriate charging current
should be selected (taking into account battery capacity and required charging time).

2. Installation.
2.1 Requirements.
Buffer power supply is designed to be installed only by qualified installer with necessary permits and
authorisations (required in installation country) to connect (interfere) with the ~230 V mains supply. Unit should be
mounted in confined spaces, in accordance, with normal relative humidity (RH=90% maximum, without condensing) and
temperature from -10°C to +40°C.
Device must be mounted in a vertical position with cable glands facing downwards. Mounting in any other
position is not permitted. Ensure free convective airflow around enclosure. In order to meet the EU requirements, follow
the guidelines on: power supply, enclosures and shielding: - according to application.
Because the power supply is designed for the continuous operation and is not equipped with ON/OFF switch, the
power supply circuit should have the appropriate overload protection. Moreover, the user shall be informed about the
method of unplugging (most frequently through separating and assigning an appropriate fuse in the fuse-box).
The electrical system shall follow valid standards and regulations.
2.2 Installation procedure.
CAUTION!
Before installation, cut off voltage in 230 V power-supply circuit. To switch power off, use an
external switch, in which distance between contacts of all poles in disconnection state is not
less than 3mm.
It is required to install in the supply circuits, in addition to power supply, circuit breaker with 6 A
nominal current.
1. Mount device and feed connection wires through glands and filler inserts. Then tighten the glands (unused
ones should be blanked off).
2. Connect power cables (~230 V) to L-N clips of PSU. Connect ground wire to clip marked by earth symbol
. Use a three-core cable (with a yellow and green protection wire) to make connection ). Lead the
power cables to the relevant terminals of the power supply via an isolation conduit. Wires should be
deisolated to a length of 7mm.
The shock protection circuit shall be done with a particular care: the yellow and green
wire coat of the power cable should be connected to the terminal marked with the grounding
symbol on the PSU enclosure. Operation of the PSU without the properly made and fully
operational shock protection circuit is UNACCEPTABLE! It can cause damage to the
equipment or an electric shock
3. If needed, connect the device cables to the technical outputs:
- EPS; technical output of AC network absence indication
- APS; technical output indicating battery failure
4. Connect equipment to the appropriate output terminals of power supply (positive connector +V, negative
connector -V).
5. Use the IBAT jumper to set the maximum battery charging current, taking into account charging capacity and
required charging time.
6. Mount the battery in the battery compartment of the enclosure. Mount the battery in the battery compartment of
the enclosure. Connect the batteries with the PSU paying special attention to the correct polarity and type of
connections.
7. Switch on ~230 V supply. LEDs on the PCB of power supply should light.
Output voltage of the PSU, without load U = 13,8 V DC.
During battery charge, voltage can amount to U = 11 - 13,8 V DC.

8. During battery charge, voltage can amount to:
-cutting off the 230 V current: EPS technical outputs will change status into opposite after about 30s
-battery disconnection: APS technical output will change status after a battery test have been completed
(~5min).
9. After installing and checking proper working, the enclosure can be closed (ensure that cover fits evenly over its
entire surface).

3. Operating status indication.
3.1 Optical indication.
Moreover, PSU is equipped with LED indicating presence of voltage at PSU output, located on PCB of PSU
module.
3.2 Technical outputs.
The PSU is equipped with indication outputs:
EPS FLT - output indicating 230 V power loss.
The output indicates 230V AC power failure In case of power failure, contacts of relay change over after
about 30 seconds.
APS FLT - output indicating battery failure.
The output indicates the PSU failure. In case of failure, contacts of relay change over. PSU failure can be
caused by the following events::
- defective or low battery
- battery fuse failure
- no continuity in the battery circuit
- battery voltage below 11,5 (23) V during battery-assisted operation
A battery failure is detected within a maximum of 5 minutes - after each battery test

CAUTION! The 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, current drawn from the PSU in battery mode should be limited. Required battery capacity can be calculated
using following formula:
QAKU=standby time *(IWY + Iz)
where:
QAKU –minimum battery capacity [Ah]
IWY –power supplies output current (drawing by the load
Iz –PSU current consumption (including optional modules) [A] (Table 4)
Total current of the receivers + battery charging current mustn’t exceed 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 IBAT
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.
