2. Installat on.
2.1 Requ rements.
AC/AC power supply shall be mounted by the qualified installer having appropriate (required and necessary for a
given country) permissions and qualifications for connecting (operating) 230 /AC installations and low-voltage
installations. The device shall be mounted in closed rooms, according to the environment class II, of the normal air
humidity (RH=90% max. without condensation) and the temperature within the range from -10°C to +40°C. The power-
supply shall operate in a vertical position so that free and convectional air flow through ventilating holes of the casing is
guaranteed.
Before installation is started, the balance of the power-supply load shall be performed. During normal operation
the sum of the currents consumed by the receivers cannot exceed I=4.0A@24 V AC. Because the power-supply is
designed for a continuous operation and is not equipped with a power-switch, therefore an appropriate overload
protection in the power supply circuit shall be guaranteed. Moreover, the user shall be informed about the method of
isolation of the power supply from the power voltage (usually through assignment and marking of an appropriate fuse in
the fuse-box). The electrical system shall be made in accordance with valid standards and regulations.
2.2 Procedure of nstallat on.
1. Before n t at ng the nstallat on t s necessary to ensure that the voltage n the 230 V power c rcu t s
d sconnected.
2. Mount the power supply in the selected place and guide connecting conductors
3. Connect the power cables (~230 AC) with L-N power supply terminals. Connect the earth conductor to the clamp
marked with earthing symbol. The connection should be performed with 3-core cable (with yellow-green PE
protecting conductor). Power conductors should be connected to proper terminals, through seal wire.
The circuit of the shock protection shall be performed with a particular care, i.e. the yellow and green
protection wire of the power cable shall be connected from one side to the terminal marked by the
symbol of in the casing of the power-supply. Operation of the power-supply without the properly
made and fully operational circuit of the shock protection is U ACCEPTABLE!
It can result in failure of devices and electric shock.
4. Connect the cables of consumers to the OUT1÷OUT4 terminals on LB4-SEP fuse block.
5. If necessary, connect device cables (alarm unit, controller, signaller, etc.) to technical outputs of the power supply:
- AW output signalling the activity of the fuse (output of the LB4-SEP fuse block).
- TAMPER output signalling opening of the power supply casing.
6. In case of installation, where significant drops in voltage in effective resistance of receiver supply cables can occur, it is
possible to correct the value of output voltage with the help of U1/U2 jumper, independently for each output.
7. Connect 230 AC supply.
8. Check optical signalling of the power supply operation: LED L1÷L4 (green) should be constantly illuminated.
9. Close the casing after installing and verifying the correctness of the power supply activity.
3. S gnall ng the operat on of power supply.
The power supply is equipped with optical signalling the status of operation. Presence of voltage on power supply outputs
is signalled by illumination of green LED diodes on the plate of LB4-SEP fuse block. Failure is signalled by red LED diode
[!] AW. Condition of the power supply may be controlled remotely by AW technical output.
3.1 Opt cal s gnall ng.
• LED L1.L4 (green) signal the supply status on OUT1÷OUT4 outputs.
In case of loss of voltage on the output (burnout of the fuse/ activation of the PTC), appropriate LED diode stops
to be illuminated (L1 for OUT1, L2 for OUT2, etc.).
• LED [!] AW (red) indicates failure of at least one output (number of the output is signalled by the green LED
L1÷L4).
3.2 Techn cal outputs.
The power supply is equipped with signalling output, enabling to submit information about the failure or sabotage.
• AW – relay type output signalling the activity of one of the output fuse.
Attent on! Fig.2 shows non-potential state of relay i.e. the state of failure.
• TAMPER - output signalling opening of the power supply casing, output of the potential-free contact signaling
the status of the power supply doors, power supply closed: NC, power supply open: NO.

4. Serv ce and operat on.
4.1 Overload and short-c rcu t of the power supply output.
Outputs OUT1÷OUT4 of the power supply are protected against short-circuits with fuse-element safety device
(inserts) or PTC. In case of damaging fuse-element safety device it is necessary to exchange the fuse (compliant with the
original).
If PTC polymer fuses protection was chosen, then automatic disconnection of the output voltage was signalled
by switching off the green diode. It is then necessary to disconnect the load from the power supply output for the period of
about 1 min.
Loading the power supply with the current exceeding Σ4.0A@24 AC (110% ÷ 150% of the S power) results in
the failure of the F
MAIN
fuse in the 230 AC circuit and/or F1÷F4 fuses. In case of failure it is essential to exchange the
fuse, compliant with original.
4.2 Ma ntenance.
All maintenance procedure may be performed after disconnecting the power supply from the power network. The
power supply unit does not require performing any special maintenance procedures, however, in case of significant drop
of the dustiness, it is only essential to remove the dust from the interior with the help of compressed air. In case of
changing the fuse it is essential to use substitutes compliant with the original parts (recommended).
WEEE MARKI G
The used electric and electronic device may not be thrown out together with common household
wastes. According to WEEE directive, binding within the EU, in case of used electric and electronic
devices separate means of utilization should be utilized.
