The buffer power-supp y is used for uninterrupted supp y of devices requiring stabi ized vo tage of 12V DC
(+/-15%). The power-supp y provides vo tage within the fo owing range: U= 11.0V÷13.8V DC of tota current
efficiency equa to 10A. In case of power vo tage decay, prompt switching to battery supp y occurs.
The power-supp y has got a meta casing (RAL 9003 co our) with a space for 17Ah/12V battery. The casing
features a micro-switch indicating door (front) opening and separating from the wa .

2. Installat on.
2.1. Requ rements.
The buffer power-supp y sha be mounted by the qua ified insta er having appropriate (required and
necessary for a given country) permissions and qua ifications for connecting (operating) 230V AC insta ations and
ow-vo tage insta ations. The device sha be mounted in c osed rooms, according to the environment c ass II, of
the norma air humidity (RH=90% max. without condensation) and the temperature within the range from -10°C to
+40°C. The power-supp y sha operate in a vertica position so that free and convectiona air f ow through
venti ating ho es of the casing is guaranteed.
Before insta ation, the ba ance of the power-supp y oad sha be performed. During the norma operation,
the sum of currents co ected by receivers sha not exceed I=10A (P=138W max.), inc uding the maximum battery
charging current Ibat.
As the power-supp y is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate over oad protection in the power supp y circuit sha be guaranteed. Moreover, the user
sha be informed about the method of iso ation of the power supp y from the power vo tage (usua y through
assignment and marking of an appropriate fuse in the fuse-box). The e ectrica system sha be made in
accordance with va id standards and regu ations.
2.2. Installat on procedure.
1. Before nstallat on s started, the voltage n the 230V power-supply c rcu t shall be solated.
2. The power-supp y sha be mounted in a se ected ocation and connection cords sha be ead.
3. The power cab es (230 VAC) sha be connected to L-N termina s of the power supp y. The earth conductor
sha be connected to the termina marked by the earth symbo . The connection sha be made by means of
a three-core cab e (with a ye ow and green PE protection wire). The power cab es sha be ead to appropriate
termina s of the connection board through bushing.
The c rcu t of the shock protect on shall be performed w th a part cular care, .e. the
yellow and green protect on w re of the power cable shall be connected from one s de to
the term nal marked by the symbol of n the cas ng of the power-supply. Operat on of
the power-supply w thout the properly made and fully operat onal c rcu t of the shock
protect on s UNACCEPTABLE! It can result n fa lure of dev ces and electr c shock.

4. Connect the conductors of the oads to the +AUX-, +AUX1-, +AUX2-, +AUX3- termina s of the termina box on
the power-supp y unit.
5. If necessary, connect the conductors from the equipment to the technica outputs:
- BS AC status indication (a arm pane , contro er, signa ing unit, LED diode, etc.)
- AW technica output of fai ure
- TAMPER signa ization of power-supp y unit opening or separating from foundation.
6. Using the jumper ‘J1’, ‘J2’ determine maxima battery charging current, take into consideration battery
parameters (refer to tab.1 page 4).
7. Using the jumper ‘J’ determine whether the function of disconnecting the discharged battery U<10V (+/-5%) is
to be on or off. The battery protect on s on f the jumper ‘J’ s removed.
8. Activate the 230V AC supp y (the AC diode shou d be permanent y i uminated, and AUX O1, O2, O3 diode
shou d be permanent y i uminated).
9. Check the output vo tage (the power-supp y unit vo tage without oad shou d be anywhere between
13.6V÷13.9V, and during battery charging 11V÷13.8V). If the va ue of the vo tage requires adjustment, the
setting shou d be made by means of the potentiometer P1, monitoring the vo tage at the AUX output of the
PSU.
10. Connect the battery in accordance with the indications: +BAT red to ‘p us’ , -BAT b ack to ‘minus’, (the LB red
diode shou d go on and the ighting intensity shou d reduce with the charging time e apsed increasing).
11. Once the tests and contro operation have been comp eted, ock the enc osure, cabinet, etc.
3. The power supply operat on nd cat on.
3.1. Opt cal nd cat on.
The PSU is equipped with two diodes on the front pane :
RED DIODE:
• ights – the power-supp y unit supp ied with 230VAC
• does not ight – no 230VAC supp y
GREEN DIODE
• ights – DC vo tage at the AUX output of the power-supp y unit
• does not ight – no DC vo tage at the AUX output of the power-
supp y unit
Moreover, the PSU is equipped with three diodes indicating operation status: AC, LB, AUX, O1, O2, O3,
and UVP, p aced on the PCB (fig.2) of the power-supp y unit modu e:
• AC - red d ode: under norma status (AC supp y) the diode is permanent y i uminated. The absence of AC
supp y is indicated by the AC diode going off.
• LB - red d ode: indicates the battery charging process; the intensity of i umination is dependent on the
charging current.
• AUX - green d ode: indicates the DC supp y status at the output of the PSU. Under norma status, the
diode is permanent y i uminated and in the case of short-circuits or over oad, the diode goes off.
• O1, O2, O3 - green d odes: indicate the status of DC power supp y at AUX1, AUX2, AUX3 outputs, which
are independent y protected with 2.5A po ymer safety equipment. In norma state, the diode emits
continuous ight – in the case of short-circuit or over oad, the diode goes off.
• UVP – red d ode: s gnals the act vat on of the UVP overvoltage protect on. In norma state, the diode
is off – in the case of short-circuit or over oad, the diode emits continuous ight.
3.2. Techn cal outputs.
The PSU is equipped with indication outputs:
• BS - absence of AC supply output: - OC output type indicates the oss of AC supp y in a norma status,
with the supp y equa to 230V, the output is deactivated and in case of power supp y oss the PSU
activates the output after 30s.
• AW - techn cal output of fa lure: OC output type indicates fai ure the occurrence of at east one of the
fo owing fai ures: SCP, OLP, UVP, vo tage converter fai ure. In norma state (correct operation), the output
has the L status "ground" (0V) – in the case of fai ure, the output is open (hi-Z high impedance).

10
• TAMPER - output nd cates open ng the power-supply un t: output as vo t-free contacts which indicate
power-supp y unit door status and fastening to the ground: NC unit opened and/or wrong y fastened (e.g.
unit unconnected with the ground): NO.
4. Serv ce and operat on.
4.1. Overload of short-c rcu t to the power-supply output.
The output circuit has an e ectronic current protection. If permissib e va ue of the I
max
output current is
exceeded, the power-supp y unit output vo tage is disconnected and this is indicated by the O1, O2, O3 and AUX
diodes going off. The vo tage is restored automatica y, when the receivers are disconnected from the output.
Additiona y, the AUX1, AUX2, AUX3 outputs of the power-supp y unit are independent y protected, using
the PTC po ymer fuses. If the output is oaded with the current that exceeds 2.5A, the output vo tage is
automatica y disconnected, which is indicated by the O1, O2 or O3 green diode going off. The restoration of the
vo tage at the output requires the disconnecting output oad for the period of at east one minute.
In the case of the short-circuit to the AUX, BAT output, ( oad 200% ÷ 250% of the PSU power) or incorrect
connection of the battery, the fuse F1 in the battery circuit becomes permanent y damaged. The restoration of the
vo tage at the BAT output requires the rep acement of the fuse.
4.2. Battery operat on.
In the case of power fai ure, in the unit wi instant y switch to the battery assisted operation.
In order to activate the operation of the PSU from the battery itse f, connect the BAT connectors in accordance with
the indications: +BAT red to ‘p us’ and, -BAT b ack to 'minus’ of the battery and press and keep depressed for five
seconds the START pushbutton on the equipment board.
The PSU s equ pped w th the d scharged battery d sconnect on system (UPV); the conf gurat on of
funct ons through the jumper ‘J’. The battery protect on s on f the jumper ‘J’ s removed.
4.3. Ma ntenance.
Any and a maintenance operations may be performed fo owing the disconnection of the PSU from the
power supp y 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 c eaned with compressed air. In the case of fuse
rep acement, on y the substitutes in conformity to the origina ones are a owed.
