2. Installation.
2.1 Requirements.
The buffer PSU shall be mounted by a qualified installer with appropriate permissions and qualifications
for 230V/AC installations and low-voltage installations (required and necessary for a given country). The device
shall be mounted in confined spaces, according to the environment class II, with normal air humidity (RH=90%
max. without condensation) and the temperature from -
10°C to +40°C. The PSU shall work in a vertical position
that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
Before installation, prepare a PSU load balance. During normal operation, the total current drawn
by the device may not exceed I = 2,2A
*
. Maximum battery charge current: 0,3A
*
. Total device c
battery: 2,5A max
*
.
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.
1. Before installation, cut off the voltage in the 230V power-supply circuit.
2. Mount the PSU in a selected location and connect the wires.
3. Connect the power cables (~230Vac) to L-N clips of the PSU. Connect the ground wire to the clip marked by the
earth symbol PE (PSU module connector). Use a three-core cable (with a yellow and green PE protection wire) to
make the connection. Lead the cables to the appropriate clips through the insulating bushing of the connection
board.
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
‘
‘
symbol on the PSU enclosure. Operation of the PSU without the properly made and
fully operational shock protection circuit is UNACCEPTABLE! It can cause a device
failure or an electric shock.
4. Connect the
receivers’ cables to the terminals
V+ (+), V-(-)
of the PSU module.
5. Connect the power (~230V)
6. Connect the battery (mind the colours):
- battery output (+V): BAT+ cable / red,
- battery output (0V): BAT
– cable / GND / black.
7. Check the PSU operation indicator: green LED (green LED on the power supply module).
8. Check the PSU output voltage:
- the PSU voltage without load should amount to U=27,6V DC.
9. After installing and checking proper working, the enclosure can be closed.
