Total current of the receivers + battery charging current mustn’t cross maximum current of power supply.
In case of power failure, a battery back-up is activated immediately. The PSU is constructed based on the switch
mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003) which can
accommodate a battery (batteries). A micro switch indicates door opening (front cover).

2. Installation.
2.1 Requirements.
The buffer PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230 V interference and low-voltage installations. The unit should be mounted in confined
spaces, with normal relative humidity (RH=90% maximum, without condensing) and temperature from -10°C do +40°C.
The PSU shall work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the
enclosure.
As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an
appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user shall be informed
about the method of unplugging (usually through assigning an appropriate fuse in the fuse-box). The electrical system
shall follow valid standards and regulations.
2.2 Installation procedure.
CAUTION!
Before installation, make sure that the voltage in the 230 V power-supply circuit is cut off.
To switch off power use an external switch in which the distance between the contacts of all poles in
the disconnection state is not less than 3mm.
It is required to install an installation switch with a nominal current of min. 6 A in the power supply circuits
outside the power supply unit.

Green LED AC:
on –the PSU is supplied with 230V AC,
off –no 230 V power, battery-assisted operation
Green LED DC:
on –presence of DC voltage in the output of the PSU
off –no voltage in the output of the PSU
Red LED CHARGE:
off –no battery charge
on - battery charging process
1. Mount the PSU in a selected location and connect the wires.
2. Connect the power cables (~230 V) to AC 230 V clips of the transformer. Connect the ground wire to the clip
marked by the earth symbol . Use a three-core cable (with a yellow and green protection wire) to make the
connection. Lead the cables to the appropriate clips of the subplate through the insulating bushing.
The shock protection circuit shall be performed with a particular care, i.e. the yellow and
green wire coat of the power cable shall stick to one side of the ‘ ’ terminal - in the PSU
enclosure. Operation of the PSU without a properly made and fully operational shock
protection circuit is UNACCEPTABLE! It can cause a device failure or an electric shock.
3. Check output voltage and adjust if necessary using potentiometer (see table: displaying parameters of the power
supply).
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 the battery parameters.
6. Mount the battery in the battery compartment of the enclosure (Fig. 3). Connect the batteries with the PSU
paying special attention to the correct polarity and type of connections (Fig.4):
a) b) c)
.
Fig. 4 Connecting batteries depending on voltage version of power supply:
a) version 12V, b) version 24V, c) version 48V
7. Switch on the 230 V supply. LEDs on cover of power supply should light (CHARGE diode only during charging).
8. After installing and checking proper working, the enclosure can be closed.
3. Operating status indication.
The power supply unit features LED and acoustic 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.

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.
