2. Installation.
2.1 Requirements.
The buffer PSU module is dedicated for installation by the qualified electrician, holding relevant permits
and licenses (applicable and required for the specific country) for connecting (interference with) the 230V/AC and
low-voltage systems. The unit should be mounted in the non-open premises, in accordance with the II-nd
environmental class, with the normal relative humidity (RH=90% maximum, without condensing) and temperature
within the range -10°C to +40°C. The should be operated in the position ensuring that the air may freely flow
through ventilation openings in a convectional way.

Prior to entering for the installation, the balance of load should be drawn up. Pending the normal
operation, the sum of currents consumed by the consumers may not exceed I=3,5A, including baterry charging
current I
bat
.
As the PSU module is designed for constant operation, it is not equipped with supply isolator, the proper
overload protection in the supply circuit should be ensured. Also the user should be advised of the methods of
disconnecting the PSU module from the supply voltage (most frequently through the separation and indication of
the relevant fuse in the fuse box). The wiring system should be completed in accordance with the applicable
standards and regulations.
The unit should be installed in the metallic enclosure (cabinet, equipment) and, in order to meet the
requirements of U, the following rules should be observed: supply, development, shielding - accordingly to the
application.
The module requires 18÷22V AC power supply with galvanic separation (transformer insulation) from the
230 V AC network. Transformer power shall be selected according to the diagram S=f(I) (diagram 1).
Diagram.1. Relation between the required transformer capacity S and the output current I of the PSU module.
2.2 Installation procedure.
1. Install the enclosure or cabinet and insert the cabling through the cable passes
2. Install the PSU module voltage reducer on the assembly bolts (the bolts should be installed prior to the operation
of enclosure or cabinet assembling).
3. Deliver the AC or DC voltage to the ~AC~ terminals. For DC voltage, correct polarization is showed in the figure
no. 2.
4. Connect the conductors of consumers to the +AUX, -AUX terminals of the terminal box on the PSU module
5. If necessary, connect the conductors from the equipment to the technical output COM-NC-NO (alarm panel,
controller, signaling unit, L D diode, etc.). BS – AC supply failure output, AW – technical output of the power
supply operation status.
6. Set the appropriate battery charging current - jumper ‘J1’ (refer to table 1 and figure 2).
7. Using the jumper ‘JP-B’ determine whether the function of disconnecting the discharged battery U<10V (+/-5%)
is to be on or off. The batter protection is on if the jumper ‘JP-B’ is removed.
8. Activate the ~230V/AC supply (the AC red diode should be permanently illuminated, and AUX diode should be
permanently illuminated)
9. Check the output voltage (the PSU module voltage without load should be anywhere between 13,6V÷13,9V,
and during battery charging 11V÷13,8V). If the value of the voltage requires adjustment, the setting should be
made by means of the potentiometer P, monitoring the voltage at the AUX output of the PSU module .
10. Connect the battery in accordance with the indications: +BAT red to ‘plus’ , -BAT black to ‘minus’, (the LB
diode should go on and the lighting intensity should reduce with the charging time elapsed increasing).
11. Once the tests and control operation have been completed, lock the enclosure, cabinet, etc.

3. PSU module operation indication.
3.1 Optical indication.
The PSU module is equipped with three diodes indicating operation status: AC, LB, AUX.
• AC- red diode: under normal status (AC supply) the diode is permanently illuminated. The absence of AC
supply is indicated by the AC diode going off.
• LB – red diode: indicates the battery charging process; the intensity of illumination is dependent on the
charging current.
• AUX- green diode: indicates the DC supply status at the output of the PSU module . Under normal status,
the diode is permanently illuminated and in the case of short-circuit or overload, the diode goes off.
3.2 Technical output:
The PSU module is equipped with indication outputs:
• BS - AC suppl absence indication: - OC output type indicates AC supply loss in a normal status, while
supplying 230V the output is disconnected in case of supply loss, the power supply connects the output
after 20s.
• AW- technical output – power suppl operation status: OC type output can indicate a power supply
failure (shorting or overload): in a normal status (while proper operation) of regulator the output is short to
ground (0V) and in case incorrect operation parameters (voltage, temperature) the output is switched into
high impedance state – hi-Z.
4. Handling and operation.
4.1 Overload or short-circuits to the PSU module output.
The AUX output of the PSU module is equipped with the PTC polymer fuse assisted protection. If the load
of the PSU module exceeds Imax. (load 110% ÷ 150% @25ºC of the PSU module power), the output voltage is
automatically disconnected and this is indicated by the green diode going off. The voltage at the output may be
restored by disconnecting the output load for the period of about one minute.
In the case of the short-circuit to the AUX, BAT output, (load 200% ÷ 250% of the PSU module power) or
incorrect connection of the battery, the fuse F1 in the battery circuit becomes permanently damaged and the
restoration of the voltage at the BAT output requires the replacement of the fuse.
4.2 Batter assisted operation.
In the case of power failure, in the unit will instantly switch to the battery assisted operation.
In order to activate the operation of the PSU module from the battery itself, connect the BAT connectors in
accordance with the indications: +BAT red to ‘plus’ and, -BAT black to 'minus’ of the battery and press and keep
depressed for five seconds the START pushbutton on the equipment board.
The PSU module is equipped with the discharged batter disconnection s stem; the configuration of
functions through the dip switch ‘JP-B’. The batter protection is on if the dip switch ‘JP-B’is removed.
4.3 Maintenance
Any and all maintenance operations may be performed following the disconnection of the PSU module
from the power supply network. The PSU module 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 fuse replacement, only the substitutes in conformity to the original ones are allowed.
