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 230 V 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 -25
°C to +40°C (table 5). The PSU shall work in
a vertical or horizontal position.
Before mounting the PSU module, perform a load balance. During normal operation, total current drawn by
the receivers cannot exceed
I=6 A.
As the PSU 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 (usually through assigning an appropriate fuse in the fuse-box). The
electrical system shall follow valid standards and regulations.
2.2 Installation procedure.
Before installation, make sure that the voltage in the 230 V power-supply circuit is cut off. To
switch power off, use an external switch, in which the distance between the contacts of all
poles in the disconnection state is not less than 3 mm.
1.
Mount the PSU in a selected location and connect the wires.
2. Connect the power cables to the L-N terminals.
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.
3. Connect the ground wire to the terminal marked by the earth symbol
“
”. Use a three-core cable (with a yellow
and green protection wire
) to make the connection. Lead the cables to the appropriate terminals of the
connection board through the bushing.
4. Connect the conductors of consumers to the terminals 24 V
– 0 V and/or the terminal box on the power-supply
unit (the balance of the power-supply load shall be performed).
5. Restore the mains power ~230 V.
6. Once the tests and control operation have been completed, close the PSU.
3. Operation and use.
3.1 Overload or short circuit at the PSU output
The 24 V
– 0 V PSU outputs are protected against a short circuit with glass fuse. If the PSU is loaded with
current exceeding 6 A
(110%for ÷ 150% of S power), there occurs the F2 and/or F1 fuse damage in the 230 V
circuit. In case of a failure, replace the fuse of the same parameters.
