5. Installation.
5.1. Requirements.
The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for ~230 V in and low-voltage installations.
As 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 should operate in a vertical position in order to provide free and
convectional air flow through ventilating holes of the casing.
As the PSU performs a periodic battery test, measuring the resistance of connections, special attention
should be paid to the proper connection of the cables to the batteries. Installation cables should be firmly
connected to the battery side terminals and to the power supply connector. If necessary, it is possible to
permanently disconnect the battery from the power supply systems by removing the F
The side walls of the housing include the embossings, which should be used to carry out installation
cables. Use a blunt instrument to make an opening for cable gland from the outside of the housing. Then, carefully
mount the cable gland, protecting the PSU from water penetration, in the opening.

5.2. Installation procedure.
It is required to install an installation switch with a nominal current of min. 3A in the power supply circuits
outside the power supply unit.
1. Mount the PSU in a selected location with use of special metal expansion bolts. Do not use PVC dowels.
2. Connect the power cables (~230 V) to the L-N terminals of the PSU. The cable length inside the housing
should not exceed 10 cm. Connect the ground wire to the terminal marked with grounding symbol. Use a
three-core cable (with a yellow and green 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 grounding symbol on the
PSU enclosure. 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.
3. Connect the receivers’ cables to the AUX1 and AUX2 output terminals on the PSU board.
4. If needed, connect the cables from the devices to the technical inputs and outputs:
- ALARM; technical output of collective failure of the PSU
- EPS FLT; technical output of AC power loss indication
- PSU FLT; technical output of PSU failure.
- APS FLT; technical output of the battery failure.
- EXTi; input of collective failure
5. Install the batteries in a designated area of the enclosure (see Fig. 4). Connect the batteries with the PSU
paying special attention to the correct polarity. Batteries must be connected in series using the special
cable (included). Attach the temperature sensor to any of the batteries with mounting tape (included).
6. Switch on the ~230 V supply. The corresponding LEDs on the power supply PCB should be ON: green AC
and green AUX1 and AUX2. Green LB LED should light up while charging.
7. 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 (see section 4.1).
8. Once the tests are completed, close the enclosure.

15
6.2.1. Voltage indicator „Uo1”, „Uo2”
Voltage indicator displays the measured output voltage at the AUX1 and AUX2 outputs. If the voltage drops
below 26 V or exceeds 29.2 V, the PSU will indicate a failure.
The resolution of voltage measurement is 0.1 V and should be treated with caution. If a greater accuracy is
required, use a multimeter.
6.2.2. Total current of the receivers indicator „Io”
Total output current indicator displays the measured output current drawn from the AUX1 and AUX2
outputs. If the value of total current is exceeded, the power supply unit will indicate a failure.
Io = IAUX1 + IAUX2
The resolution of current measurement is 0.1 A and should be treated with caution. If a greater accuracy is
required, use a multimeter.
6.2.3. Resistance of the battery circuit indicator „bre”
Resistance of the battery circuit indicator displays the measured resistance of the battery circuit of the
PSU. The resistance value is affected by:
- The quality of the batteries
- The quality of the battery cables and connections
- The quality of the FBAT fuse
If the resistance value increases above 300 mΩ, the power supply unit will indicate a failure.
The measurement result is displayed with a resolution of 0.01 ohm.
6.2.4. Battery temperature indicator „t°C”
Battery voltage indicator displays the measured temperature of the batteries. The temperature is used by
the automatic control system for compensation of the battery charging voltage.
The measurement result is displayed with a resolution of 1°C.
6.2.5. 230 V mains voltage indicator „UAC”
230 V mains voltage indicator displays the measured mains voltage at the ~230 V mains terminals. If the
voltage drops below 195 V AC or exceeds 254 V AC, the power supply unit will indicate a failure.
The resolution of current measurement is 1 V and should be treated with caution. If a greater accuracy is required,
use a multimeter.
6.2.6. Failure history “FLh” .
The PSU remembers 30 last failures in non-volatile memory, which can be reviewed later.
In order to review the failures, use the "<" or ">" button to set the FLh parameter and confirm by pressing "OK".
The display will show the number of failure in the memory and its code. Pressing the "OK" button again will display
next failure in the memory.
The memory of the new power supply remembers the events that are the result of the efficiency tests
carried out at the production stage.

6.4. Technical outputs.
The PSU is equipped with galvanically isolated indication outputs changing status after a specified event:
EPS FLT – output indicating 230 V power loss.
The output indicates 230 V power loss. Under normal status – with the 230 V supply on, the output is closed. In
case of power failure, the PSU will switch the output into the open position after a time lag determined in the „EPS”
configuration menu (see section 6.3.3, Table 10).
APS FLT – output indicating battery failure.
The output indicates a failure in the battery circuit. Under normal status (during correct operation) the
output is closed. In case of failure, the PSU will switch the output into the open position. Failure can be triggered by
the following events:
- faulty batteries
- undercharged batteries
- disconnected batteries
- high resistance of the battery circuit
- battery voltage below 23 V during battery-assisted operation
- battery fuse failure
- no continuity in the battery circuit
PSU FLT – output indicating PSU failure.
The output indicates the PSU failure. Under normal status (during correct operation) the output is closed. In
case of PSU failure, it will switch into the open position. Failure can be triggered by the following events:
- U

ALARM - technical output of collective failure indication.
Output indicating collective failure. In the case of failure at any EPS, APS, or PSU output or at the EXTi
input, the collective failure signal ALARM will be generated.
CAUTION! In Fig.2 the set of contacts shows a potential-free status of the relay, which
corresponds to power supply collective failure of the PSU.
www.pulsar.pl EN54-7A17 RED POWER
27
6.5. Input of collective failure: EXTi.
The EXT IN (external input) technical input indicating collective failure is intended for additional, external
devices that generate the failure signal. The voltage appearing at the EXT IN input will trigger PSU failure, storing
the information about the event in the internal memory and sending the signal about the failure to the ALARM
output.
The EXT IN technical input has been made with galvanic isolation between the PSU’s systems and the
attached devices.
Fig. 11. Electrical diagram of the EXT IN input.
The connection of external devices to the EXT IN input is shown in the electrical diagram below. OC
outputs (open collector) or relay outputs can be used as the source of the signal.
Fig. 12. Examples of connections.
In the option with external switch, the V
jumper, which polarises the EXT IN input circuit and is
EXT
required in such configuration, must be on.
The EXTi input has been adjusted to work with fuse modules generating a failure signal in case of a fuse
fault in any of output sections (see section 6.7). To guarantee a correct cooperation between the fuse module and
the EXTi input, the connections shall be made as presented in the diagram below and the V EXT jumper must be
on.
Fig. 13. Example of a connection with the fuse module EN54-LB8.
www.pulsar.pl EN54-7A17 RED POWER
28
6.6. Indication of the enclosure opening - TAMPER.
The PSU is fitted with the microswitch tamper indicating enclosure opening.
The tamper cable is not connected to the terminal in the factory settings. In order to activate tamper,
remove the jumper from tamper terminal (Fig. 2 [12]) and plug in the tamper cable.
Each opening the enclosure will generate a failure signal at the PSU FLT and ALARM technical outputs
and will save the event in the internal memory of the PSU.
6.7. Increasing the number of outputs with optional EN54-LB4 or EN54-LB8 fuse
modules.
The PSU has two independently protected outputs for connecting the AUX1 and AUX2 receivers.
If the power supply unit is connected with more receivers, then it is recommended to secure each of them with
independent fuse. This solution will protect the power supply system, while the damage to only one receiver (shortcircuit on the line) could cause damage to other receivers connected to the same output.
The solution is provided by the optional fuse module EN54-LB4, 4-channel or EN54-LB8, 8-channel, while
its mounting location is provided within the housing (see Fig. 4). The figure below shows the connection between
the power supply, fuse module and receivers.
Fig.14. The connection of fuse module.
When installing the fuse module in the PSU, power supply current consumption, used for the
calculation of standby time (see section 7.8), should be taken into account.
Depending on the version, fuse module allows to connect 4 or 8 receivers to the PSU. Output state is indicated by
green LEDs.
Blown fuse is indicated as follows:
- corresponding LED turns off: L1 for AUX1 etc.
- red LED on
- PSU technical output on (Hi-Z state)
- switching PSU relay output into voltage free status (contacts as shown in the Fig.14).
In addition, blown fuse signal is transmitted to the input of collective failure EXTi (ALARM) and saved in the
internal memory of PSU.
The PSU’s relay output can also be used for remote control, including external optical indication.
www.pulsar.pl EN54-7A17 RED POWER
29
6.8. Overvoltage protection of the PSU output OVP.
In case of voltage exceeding 30,5 V±0.5 V at the switching regulator’s output, the system cuts off
the power at the outputs to protect the battery and the receivers from damage. The outputs will be batterypowered. The activation of the protection system is indicated by the OVP yellow LED on the PCB board, and the
PSU FLT and ALARM outputs.
6.9. PSU overload.
The PSU is fitted with the LED OVL (overload) on the PCB and indicator on the LED panel,
informing about output overload. If the nominal current of the PSU is exceeded, the led turns on and the
microprocessor starts a specially implemented procedure. Depending on time and overload level,
microprocessor may disconnect the AUX1 and AUX2 outputs and switch into the battery-assisted operation.
Restart will occur after 1 minute.
PSU overload is indicated by the PSU FLT and ALARM technical outputs.
6.10. Indication of exceeding Imax a current.
Exceeding the "Imax a" output current during the power supply operation is indicated by the
microprocessor using the LED OVL light (overload) on the PCB and LED indicator light on the LED panel
of the power supply after 30 seconds.
Information about exceeding the „Imax a” current is stored in the history of events. Battery charge current is
limited in order to protect the power supply against overload.
6.11. Short-circuit of the PSU output.
In case of short-circuit of the AUX1 or AUX2 output, one of the fuses - F
permanently blown. The restoration of the voltage at the output requires the replacement of the fuse

7. Reserve power supply circuit.
The PSU is fitted with intelligent circuits: battery charging circuit with the function of the accelerated
charging and battery control, which main task is to monitor the condition of the batteries and the connections in the
circuit.
If the controller detects a power failure in the battery circuit, appropriate indication and activation of the APS
FLT and ALARM technical outputs takes place.
7.1. Battery detection.
The control unit of the PSU checks the voltage at the battery terminals and, depending on the measured
values, determines the appropriate reaction:
U
below 4 V - batteries not connected to the PSU circuits
BAT
U
= 4 to 20 V - faulty batteries
BAT
U
over 20 V - batteries connected to the PSU circuits
BAT
7.2. Protection against short-circuit of the battery terminals.
The PSU is fitted with the circuit protecting against short-circuit of the battery terminals. In case of short
circuit, control circuit immediately disconnects the batteries from the rest of the power supply circuit, so the loss of
output voltage on power supply outputs is not observed. Automatic reconnection of the batteries to the PSU's
circuits is only possible after the removal of the short-circuit and correct connection of the circuits.
7.3. Protection against reverse battery connection.
The PSU is protected against reverse connection of the battery terminals. In case of incorrect connection,

7.6. Measurement of the resistance of the battery circuit.
The PSU is checking the resistance in the battery circuit. During the measurement, the PSU driver takes
A failure may indicate considerable wear or loose cables connecting the batteries.
www.pulsar.pl EN54-7A17 RED POWER
31
7.7. Battery temperature measurement.
The PSU has a temperature sensor to monitor the temperature parameters of installed batteries. The sensor is
located near the batteries; hence, temperature readings should not be confused with the ambient temperature.
Temperature measurement and compensation of the battery charging voltage can extend the life of the
batteries.
7.8. Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an
appropriate standby time, current drawn from the PSU in battery mode should be limited.
Required, minimum battery capacity to work with the PSU can be calculated with the following formula:
Q
= 1.25 ﴾ ﴾Id + Iz﴿ •Td + ﴾Ia + Iz﴿ •Ta + 0.05 Ic ﴿
AKU
where:
Q
– The minimum battery capacity [Ah]
AKU
1.25 – the factor related to the decrease in battery capacity due to aging
Id – the current drawn by the load during inspection [A]
Iz – PSU current consumption [A]
Td – required inspection time [h]
Ia – the current drawn by the load during an alarm [A]
Ta – alarm duration [h]
Ic – short-term output current
Rearranging the above equation, the approximate runtime of the system with two 17 Ah batteries can be
determined.
The following data can be assumed:
Id = 2,5 A
Iz = 0,078 A
Ia = 5 A
Ta = 0,5h
Ic = 7 A
The approximate runtime of the system with two 17 Ah batteries will amount to 4h 9min.
www.pulsar.pl EN54-7A17 RED POWER
32
8. Remote monitoring (options: Wi-Fi, Ethernet, RS485, USB).
The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a
monitoring centre. Transmitting data concerning PSU status is possible due to an additional, external
communication module responsible for communication in Wi-Fi, Ethernet or RS485 standard. The USB –TTL
interface enables the connection between the PSU and the computer.
Different connection topologies, presented later in this chapter, are only a part of possible communication
schemes. More examples can be found in the manuals dedicated to individual interfaces.
When installing optional features in the power supply unit, power supply current consumption, used
for the calculation of standby time, should be taken into account (see section 7.8.).
8.1. Communication via the USB-TTL interface.
The easiest way of communication between the PSU and the computer is provided by the USB-TTL "INTU”
interface. This interface allows direct connection between the computer and the PSU and is recognizable by the
operating system as a virtual COM port.
Fig. 15. USB-TTL communication using the USB-TTL „INTU” interface.
8.2. ETHERNET network communication.
Communication in the Ethernet network is possible due to the additional interfaces: Ethernet „INTE” and
RS485-ETH „INTRE”, according to the IEEE802.3 standard.
The Ethernet „INTE” interface features full galvanic isolation and protection against surges. It should be
mounted inside the enclosure of the PSU.
Fig. 16. Ethernet network communication using the Ethernet „INTE” interface.
www.pulsar.pl EN54-7A17 RED POWER
33
The RS485-WiFi „INTRE” interface is a device used to convert signals between the RS485 bus and the WiFi network. For proper operation, the unit requires an external power supply in the range of 10÷30 V DC e.g.
drawn from a PSU of the EN54 series. The unit is mounted in a hermetic enclosure protecting against adverse
environmental conditions.
Fig. 17. Ethernet network communication using the RS485 „INTRE” interface.
8.3. The Wi-Fi wireless communication.
The Wi-Fi wireless communication can be implemented on the basis of additional interfaces: WI-Fi ‘INTW’
and RS485-WiFi, operating within 2,4GHz frequency band, according to the IDEE 802.11 bgn standard.
The WiFi “INTW” interface shall be mounted in a selected location inside the enclosure so that the
antenna is exposed to the outside.
Fig. 18. The Wi-Fi communication using WI-FI „INTW” interface.
www.pulsar.pl EN54-7A17 RED POWER
34
The RS485-WiFi „INTRW” interface is a device used to convert signals between the RS485 bus and the
WiFi network. For proper operation, the unit requires an external power supply in the range of 10÷30 V DC e.g.
drawn from a PSU of the EN54 series. The physical connection of the interface takes place under galvanic
isolation. The unit is mounted in a hermetic enclosure protecting against adverse environmental conditions.
Fig. 19. The Wi-Fi communication using the RS485-WIFI „INTRW” interface.
8.4. RS485 network communication.
Another type of network communication is the RS485 communication using two-wire transmission path. To
achieve this kind of data exchange, the PSU should be equipped with the additional RS485 TTL "INTR" interface,
converting data from the PSU into the RS485 standard and the USB-RS485 "INTUR" interface, converting data
from the RS485 network to the USB. Offered interfaces are galvanically isolated and protected against surges.
Fig. 20. RS485 communication using the „INTR” and „INTUR” interfaces.

8.5. „PowerSecurity” program.
The ”Power Security” program is available on www.pulsar.pl
Its detailed description can be found in the manual.
PowerSecurity is a program designed to operate with power supplies of the PSBEN, EN54 and
EN54C/LCD series.
The graphical interface of the program has been designed so that it is convenient to combine power
supplies into groups giving the possibility of monitoring multiple parameters in one window simultaneously.
The program constantly monitors the parameters of all power supplies; in case of failures the backlight changes
accordingly in both the manager window and the Windows taskbar. In addition, the program allows you to
download the operation history of the power supply, the history of events, and visualization in the form of charts
and tables. The downloaded data can be saved.
The program also provides functionality in the form of a remote battery test. The result of the battery test
takes the form of a message.
The PowerSecurity software is a free software. Operation requires a PC with the operating system
Windows 10 or older.
The application can also be used by people who install and service power supplies. The main panel of the
program is shown below.
Fig. 21. The main panel of the "Power security" program.
www.pulsar.pl EN54-7A17 RED POWER
36
Fig. 22. The main panel of the "Power security" program - the "Synoptic board" tab.
The manager window allows you to combine monitored power supplies into groups / subgroups offering
greater control and transparency for more complex systems.
The device window can be switched between two modes: the synoptic board or the list mode. This is
especially useful when the PowerSecurity program works with a large number of power supplies.
The application enables both visualization and analysis of read data. Exceeding the permissible
parameters is signaled by a change in color of the relevant field to yellow and a flashing indicator light. It is possible
to view the current power supply parameters, historical parameters in the chart, electrical parameters, the status of
technical outputs, and to read the event log on individual tabs.

10. Technical inspections and maintenance.
Technical inspections and maintenance 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 it is used in dusty conditions. In case of fuse replacement, use only compatible replacement
parts.
Technical inspections should be carried out not less frequently than once per year. During the inspection,
check the batteries and run the battery test.
4 weeks after installation, re-tighten all threaded connections, see Fig. 2 [11] and Fig. 3 [2].
CAUTION!
According to the recommendations of the CNBOP and VdS institutes, the batteries should
be replaced after four years of service, regardless of their status.
