ought to be followed- accordingly to the application. The module requires 27-30V AC power supply with galvanic
separation (transformer insulation). The minimum power of the transformer: 40VA.
2.2 Installation procedure
1. Install an enclosure, a distribution board or a cabinet and lead the cables through the cable ducts.
2. Install the PSU module on the DIN rail: Mount the module onto the rail and block with a clip (Fig. 3)
3. Deliver the output voltage from the AC transformer to the ~AC~ terminals (27-30V, min40VA).
4. Connect the receivers’ cables to the +AUX, -AUX terminals of the terminal block on the PSU module’s board.
5. If necessary, connect the device conductors to the technical output, two pairs of contacts Cx-NCx-NOx
(alarm panel, controller, indicator, LED, etc.)
6. Activate the ~230V/AC supply (the AC red diode and AUX green diode should be permanently illuminated)
7. Check the output voltage (the PSU module voltage without load should amount to 27,6V-27,8V, during battery
charging 22,0-27,6VV). If the value of the voltage requires adjustment, it should be set by the V
adj
potentiometer,
monitoring the voltage at the AUX output of the PSU module.
8. Connect the battery in accordance with the signs: +BAT red to ‘plus’, -BAT black to ‘minus’, (the LB red diode will
be lit and the light should fade throughout the time of charging).
9. Once the tests and operation control have been completed, the enclosure/cabinet can be locked.

3. Operating status indication.
3.1 LED indication
The PSU module is equipped with four diodes indicating operating status: AC, LB, AUX, F
BAT
.
•
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 out.
•
AUX- green diode: indicates the DC supply status in the output of the PSU module. Under normal status,
the diode is permanently illuminated. In case of a short circuit or overload the diode goes out.
•
LB- yellow diode: indicates battery charging process, the light intensity depends on the battery charging
current: 0,5A=100%.......0,0A=0%.
•
F
BAT
- blue diode: under normal status, it is off. In case of fuse damage (burnt fuse-) the diode is lit.
3.2 Technical outputs
The PSU module is equipped with indication outputs:
•
FAC - absence of AC supply output: - OC type output indicating AC power loss. In normal status, with
230V AC supply, the output is connected to ground (L level– 0V). In case of power loss, the PSU will switch
the output into a high impendence state, hi-Z, after 10 seconds.
•
FAC - absence of AC supply output: - relay output indicating the absence of AC supply. In case of power
loss, the PSU module will switch the relay contacts after approx. 10 seconds.
CAUTION! In Fig.2. the contact set in the potential-free status corresponds to a state with no AC
power (AC power failure).
•
FPS - technical output of the PSU operation status: OC type output indicating the PSU failure. In
normal state (during correct operation) the output is connected to ground (L level – 0V). In case of incorrect
operating parameters (voltage, current, temperature), the output is switched into a high impendance state –
hi-Z.
