charging current should be set as follows:
Grade 1, 2 - standby time 12h:
12h standby output current can be calculated from formula:
IWY=QAKU/12 - IZ
where:
QAKU –minimum battery capacity [Ah]
Iz –PSU current consumption (including optional modules) [A] (table 3)

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 230 V mains supply. Unit should be mounted in
confined spaces with normal relative humidity (RH=90% maximum, without condensing) and temperature from -10°C to
+40°C. PSU shall work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of
enclosure.
Because power supply is designed for the continuous operation and is not equipped with ON/OFF switch, power
supply circuit should have appropriate overload protection. Moreover, user shall be informed about method of unplugging
(most frequently through separating and assigning an appropriate fuse in fuse-box). 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 3 mm.
It is required to install in the supply circuits, in addition to power supply, circuit breaker with 6 A
nominal current.
1. Mount the PSU in a selected location and connect the wires.
2. Connect power cables (~230 V) to L-N clips of PSU. Connect ground wire to clip marked by earth symbol PE .
Use a three-core cable (with a yellow and green protection wire ) to make connection). Lead power cables to
relevant terminals of power supply via an isolation conduit. Wires should be deisolated to a length of 7mm.
Shock protection circuit shall be done with a particular care: yellow and green wire coat
of power cable should be connected to terminal marked with the grounding symbol on PSU
enclosure. Operation of PSU without the properly made and fully operational shock protection
circuit is UNACCEPTABLE! It can cause damage to 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
- FPS; technical output indicating
4. Connect equipment to the appropriate output terminals of power supply (positive connector +AUX, negative
connector -AUX).
5. Use the IBAT jumper to set the maximum battery charging current, taking into account charging capacity and
required charging time.
6. Mount battery in the battery compartment of enclosure. Connect the batteries with the PSU paying special
attention to the correct polarity.
7. Switch on 230 V supply. LEDs on the PCB of power supply should light. After installing and checking proper
working, enclosure can be closed.
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. Run PSU test: check LED and acoustic indication (see section 3.1) and technical output; through:
- cutting off 230 V current: LED AC go out, EPS technical outputs will change status into opposite after
about 30 s
-battery disconnection: APS technical output will change status after a battery test have been completed
(~5 min) and red APS LED lights up.
- dismantling of one of AUX fuses: red FPS LED lights up, FPS technical output will change status.

Green LED AC:
on –PSU is supplied with 230 V,
off –no 230 V power, battery-assisted operation
Green LED DC:
on –presence voltage in output of PSU
off –no voltage in output of PSU
Red LED APS:
off –no failure
on –indicates battery failure status
3. Operating status indication.
The power supply unit features LED status indication.
3.1 Optical indication.
The power supply unit features LED status indication. Presence of voltage at output of the PSU is indicated by
the green LED L1 ÷ Ln. Failure (fuse damage) is indicated by shutting illuminating the red LED FPS. Status of the PSU
(fuse damage AUX1 ÷ AUXn) can be remotely controlled via FPS technical output.
In addition, there is an additional indication on the lid of the power supply:
3.2 Technical outputs.
The PSU is equipped with indication outputs:
FPS –indicating fuse failure
Output indicates failure of at least one of AUX1-AUXn output fuses. In case of fuse failure, relay is switched
immediately.
EPS –output indicating 230 V power loss.
The output indicates 230 V power failure. In case of power failure, contacts of relay change over after about
30 seconds.
APS –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 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 load
Iz –PSU current consumption (including optional modules) [A] (Table 3)

3.4Battery charging time.
PSU has a battery circuit charged with direct current. Current selection is done with use of IBAT jumpers.
Table below shows how long does it take to charge a (fully discharged) battery up to min. 80% of its nominal capacity.

3.5Running 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. Operation and use.
4.1. Overload or short circuit of the PSU module output.
The AUX1÷AUXn PSU outputs are protected against short circuit by glass fuses. Activation of the protection
(glass fuse blowing) is indicated by shutting down green LED nearby appropriate outputs fuse
on the PSU module and illuminating the red LED FPS. In case of damage, replace the fuse (compatible with the original).
As a precaution, it is possible to use fuses with a higher current (up to 2 A) and a fast blow characteristic (F), which will
increase the current-carrying capacity of the given output. However, this does not affect the overall current capacity of the
power supply.
Total current of the receivers + battery charging current mustn’t exceed maximum current of power
supply output current.
4.2. Operation of the PSU OVP system.
If the OVP system is activated, the output voltage is automatically cut off. Operation can be resumed after
disconnecting the PSU from 230 V after approx. 1 minute.
5. 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 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.
