2. Installation.
2.1 Requirements.
The stabilized PSU 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 +50°C. The PSU shall work in
a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
During normal operation the total current consumption of the receivers cannot exceed
I=16x0,5A
As the PSU module is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user
shall be informed about the method of unplugging (most frequently through separating and 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 PSU in a selected location and connect the wires.
3. Connect the power cables (~230VAC) to L-N terminals of the PSU. 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 shock protection circuit 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 receivers’ cables to the
AUX1…AUX8
connectors
on the
LB8/AW (A, B) strips.
5. If necessary, connect the device’s wires (of an alarm panel, controller, indicator, etc.) to the technical outputs:
-
FPS (LB8/AW A, B)
output indicating a fuse failure (outputs of the LB8/AW A,B fuse strips).
-
TAMPER
output indicating unwanted opening of the PSU’s enclosure.
6. In electrical installations with significant voltage drops in the resistance of the wires that lead to the receivers, the
voltage value can be corrected with the P1 potentiometer (12V÷15V DC).
7. Check the PSU operating status indication
8. 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 of operation status. The presence of power at the outputs of the
PSU is indicated by the illumination of green LEDs on the front panel of the device.
L
FPS
red LED [!] indicates a
failure. The status of the PSU can be remote controlled by the FPS technical output.
