LED green AC:
on
– PSU is supplied with 230 V
off
– no 230 V power
LED red FPS:
off
– no failure
on
– indicates fuse failure
1. Mount the PSU in a selected location and connect the wires.
1. Connect power cables (~230 V AC) to L-N clips of PSU. Connect ground wire to clip marked by earth symbol
.
Use a three-core cable (with a yellow and green protection wire) to make connection
).
Lead the cables to the appropriate clips through the insulating bushing of the PSU.
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.
2. Switch on 230 V supply. LEDs on power supply PCB should be ON. Optionally, you can install additional PKAZ168
signalling module (chapter 3.1).
3. Check output voltage and adjust if necessary using potentiometer.
4. Disconnect the PSU from the mains and make the rest of the connections - connect wires to the
AUX1...AUXn
connectors
.
If necessary, connect the wires from devices (control panel, controller, siren, etc.) to the PSU technical
outputs FPS (fuse failure indication output).
5.
Once the tests and control operation have been completed, close the enclosure/cabinet.
3. Operating status indication.
The power supply unit features LED status indication:
3.1 Optical indication.
Presence of voltage at each output of the PSU is indicated by the green LED nearby each outputs fuse.
Failure (fuse damage) is indicated by shutting down green LED nearby appropriate outputs fuse on the PSU module
and illuminating the red LED FPS.
Status of the PSU (fuse damage AUX1 ÷ AUXn) can be remotely controlled via the
FPS technical output.
Moreover, signalling can be extended with optional PKAZ168 module:
Caution -
one of the LEDs in the module remains inactive
4. Technical output.
The PSU features a relay type output indicating FPS fuse failure.
Caution! In Fig. 3 set of contacts shows a potential-free status of relay, which corresponds to power supply failure.

5. Operation and use.
5.1. 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.
