According to the PN-83/T-42106 standard
2.1 Requirements.
The buffer PSU should be mounted by a qualified installer, holding relevant permits and licenses
(applicable and required for a given country) for 230V/AC and low-voltage installations. The unit should be mounted in confined spaces, in accordance with the 2nd environmental class, with normal relative humidity
(RH=90% maximum, no condensation) and temperature range from 10°C up to +40°C. The power supply should operate in a vertical position in order to provide free and convectional air flow through ventilating holes of the enclosure.
The power supply load balance should be done before installation:
1. Output current 10A + 1A battery charging
2. Output current 9A + 2A battery charging
3. Output current 8A + 3A battery charging
4. Output current 6A + 5A battery charging
Total current of the receivers + battery is max. 11A
The power supply is designed for a continuous operation and is not equipped with a powerswitch. Therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the user should be informed how to disconnect the power supply unit from the mains supply (usually by assigning an appropriate fuse in the fuse box). The electrical system shall be made in accordance with applicable standards and regulations. The power supply shall be mounted in a close casing (a cubicle, a terminal device) and in order to fulfill
LVD and EMC requirements the rules for power-supply, encasing and shielding shall be observed according to application.
2.2 Installation procedure.
1. Before installation, make sure that the voltage in the 230V power-supply circuit is cut off.
2. Mount the power supply in the enclosure or cabinet and lead the connection cables.
3.
Connect the power cables (230V AC) to the L-N terminals of the PSU. Connect the ground wire to the terminal marked with the PE symbol (power supply module connector). Use a three-core cable (with a yellow and green PE protection wire) to make the connection.
The shock protection circuit shall be done with a particular care: the yellow and green wire coat of the power cable should be connected to the terminal marked with the PE symbol. Operation of the PSU without the properly made and fully operational shock protection circuit is UNACCEPTABLE! It can cause damage to the equipment or an electric shock
4. Connect the receiver cables to the AUX, AUX1, AUX2 and AUX3 terminals at the power supply board.

5. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- PSU; technical output indicating PSU failure.
- LoB; technical output indicating low battery voltage
- Optional installation of the MPSBS relay module changing technical outputs of the OC type to relay type
(page 9, section. 3.4)
6. Use the I
BAT
jumper to set the maximum battery charging current, taking into account the battery parameters.
7. Use the P
BAT
jumper to set to turn on/off deep discharge battery protection U<10V (+/-5%). Deep discharge battery protection is ON when the P
BAT jumper is OFF.
8. Mount the battery in the battery compartment of the enclosure. Connect the batteries with the PSU paying special attention to the correct polarity.
9. Switch on the 230V AC supply. The corresponding LEDs on the power supply PCB should be ON: red AC and green AUX. The yellow LB LED should light up while charging.
10. Check the output voltage (the power supply voltage without load should be 13,6 V ÷ 13,9V, 11V ÷ 13,8V while battery charging). If the voltage requires adjustment, use the V
ADJ
, potentiometer while monitoring the voltage at the AUX output of the power supply.
11. Check the current consumption of the receivers, taking into account the battery charging current, so as not to exceed the total current efficiency of the PSU (section 1.1).
12. Mount the additional optical indication plate and connect to the socket on the PCB of the power supply using a cable (Fig. 2 pt. 7).
13. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication
.
3.1 Power supply operation indication.
Additionally, the PSU is fitted with LED lights indicating the operating status: AC, LB and AUX at the PCB of the PSU:
AC - red LED : is permanently illuminated during normal operation (AC power ON). No AC power is indicated by turning off the LED.
LB - yellow LED : indicates battery charging. The light intensity depends on the charging current.
AUX - green LED: indicates DC power status at the PSU output. During normal operation, it is permanently illuminated. In case of short-circuit or output overload the LED is off.
3.2 Optical indication with the PKAZ108 additional module.
The PKAZ additional module is equipped with three LEDs indicating operation status: AC, DC, and BAT.
AC :
on – The PSU supplied with 230V AC voltage
off – no 230V AC mains supply
DC :
on – DC voltage at the AUX output
off - no DC voltage at the AUX output
BAT :
on – battery voltage U
BAT
> 11,5V
off – battery voltage U
BAT
< 11,5V

3.3 Technical outputs.
The PSU has indication outputs:
EPS - technical output indicating 230V AC power failure .
The output indicates 230V AC power failure. Under normal status – with the 230V AC supply on, the output is shorted to ground GND. In case of power failure, the PSU will switch the output into hi-Z high impedance state after a time set by the T
AC jumper.
PSU – output indicating PSU failure .
The output indicates PSU failure. Under normal status (correct operation) the output is shorted to ground
GND. If there is no DC voltage at the output (eg short circuit), the output is switched into hi-Z high impedance state.
PSU failure can be caused by the following events:
- Short circuit at the output
- Output overload
- DC/DC voltage converter failure
- Under voltage protection activation
LoB – output indicating low battery voltage.
The output indicates low battery voltage. Under normal status (U
BAT
> 11,5V) the output is shorted to ground GND, when the battery voltage drops too low (U
BAT
< 11,5V) the output is switched into hi-Z high impedance state.
The power supply unit does not feature a battery detection function. In the case of no battery or non battery connected, the output is in the normal mode.
The power supply technical outputs are open collector (OC) type, as shown schematically below.
Fig. 4. Electrical diagram of the OC technical outputs.
3.4 Relay technical outputs.
If the OC type outputs are not sufficient to control the unit, it is possible to use the MPSBS relay module changing technical outputs of the OC type to relay type.
Fig. 5. The diagram of connecting the MPSBS module.

4. Service and operation.
4.1 Overload or short-circuit of the power supply output (SCP activation).
The AUX output of the PSU is protected against short-circuit by PTC polymer fuse. If the power supply load current exceeds Imax. (110% ÷ 150% @ 25°C of the PSU power), automatic disconnection of the output voltage, indicated by switching off the green LED, takes place. To restore the voltage at the output, disconnect the load from the power supply output for approximately 1 minute.
In case of a short-circuit at the AUX, BAT output or reverse battery connection, the F
BAT
fuse in the battery circuit becomes permanently damaged. The voltage restoration at the BAT output requires fuse replacement.
4.2 Running the PSU from the battery.
The power supply is equipped with the button on the PCB allowing to run the PSU from the battery, when needed. To do that, press and hold the START button on the unit board for 1 second.
4.3 Deep discharge battery protection UVP.
The power supply is equipped with deep discharge battery protection (UVP). If the voltage at the battery terminals drops below 1
0V±0.5V during battery-assisted operation, the batteries will be disconnected.
The battery protection is on when the P
BAT jumper is off.
Caution.
It is not recommended to disable UVP since deep discharge of the batteries reduces their ability to store energy, their capacity and lifetime.
4.4 Maintenance.
All maintenance procedures can be performed after disconnecting the power supply from the power network.
The PSU does not require any specific maintenance; however, its interior should be cleaned with compressed air if used in dusty conditions. In case of fuse replacement, use only compatible replacement parts.
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.
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.
