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=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.

. Connect the receivers’ cables to the
AUX1…AUX5
connectors
on the
LB5 strips.
5. 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).
6. Check the PSU operating status indication
7. 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.
3.1. LED indication
LED1…LED5
green diodes indicate power at the outputs:
LB5-
AUX1…..AUX5.
In case of a power loss at the output (fuse activation), an appropriate diode goes out. (L1 for AUX1, L2 for
AUX2 etc.)
