2. Installation.
2.1 Requirements.
The AC/AC power supply is to be mounted by a qualified installer, holding relevant permits and licenses
(applicable and required for a given country) for 230V/AC interference 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, without condensation) and temperature from -10°C to +40°C. The PSU shall wor k in
a vertical position that guarantees free convectional air flow through the ventilating holes of the enclosure
Before installation is started, the balance of the power-supply load shall be performed. During normal
operation total current drawn by the receivers cannot exceed I=4.0A@24V AC. As the PSU 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 unplugging
(usually through assigning an appropriate fuse in the fuse-box). The electrical system shall follow valid standards
and regulations.
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 selected location and connect the wires.
3. Connect the power cables (~230V AC) with L-N power supply terminals. Connect the ground wire to the terminal
marked by the earth symbol – “
”. Use a three-core cable (with a yellow and green PE protection wire) to make
the connection. Lead the cables to the appropriate terminals of the connection board through the bushing.
The circuit of the shock protection shall be performed with a particular care, i.e. the yellow
and green wire coat of the power cable shall stick to one side of the terminal marked with
the '
' earth symbol in the PSU enclosure. Operation of the power supply without a
properly made and fully operational shock protection circuit is UNACCEPTABLE! It can
result in device damage or an electric shock.
.
4. . Connect the cables of receivers to the OUT1÷OUT4 terminals on LB4-SEP fuse block.
5. If necessary, connect devices’ wires (alarm panel, controller, indicator, etc.) to the PSU’s technical outputs:
- AW output indicating fuse activation (output of the LB4-SEP fuse block).
- TAMPER output indicating unwanted opening of the PSU enclosure
6. In case of installation, where significant voltage drops occur in the resistance of the cables leading to the
receivers, there is a possibility of voltage value correction by the U1/U2 jumpers, independently for each output.
7. Connect 230V AC supply.
8. Check LED indication for PSU operating status: LED L1÷L4 (green) should be constantly illuminated.
9. Once the installation and operation control have been completed, the enclosure can be locked.
3. Operating status indication.
The PSU is equipped with LED indication the status of operation. The presence of power at the outputs of the PSU
is indicated by the illumination of green LEDs on the PCB of the LB4-SEP fuse block. A failure is indicated by the
red LED [!] AW. The PSU status can be remotely controlled by the AW technical output.
