2. Installation
2.1 Requirements
The buffer PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable
and required for a given country) for 230V/AC 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 condensing) and 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.
1. Output current 1A (without a battery)
2. Output current 0,9A + 0,1A battery charge
Total current of the rec battery: 1A 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
Before installation, make sure that the voltage in the 230V power-supply circuit is cut off.
1. Mount the PSU in a selected location and connect the wires.
2. Connect the power cables (~230Vac) to L-N clips of the PSU. Connect the ground wire to the clip 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 clips through the insulating 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 ‘
‘
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.
3. Connect the receivers’ cables to the + AUX, - AUX connectors of the terminal block on the PSU board (optionally
connect the MZN1 module to the + AUX
output, and the receivers to the module’s output).
4. If necessary, connect the device conductors to the TAMPER technical output (the indicator preventing the PSU
from unwanted opening)
5. Activate the ~230V AC supply (the AC diode and the AUX diode should be permanently illuminated)
6. Check the output voltage (the PSU voltage without load should amount to 13,6
V÷ 13,9V, during battery charge:
12,8V÷13,8V). If the value of the voltage requires adjustment, it should be set by the P1 potentiometer, monitoring
the voltage at the AUX output of the PSU.
7. Connect the battery in accordance with the markings (colours):
+BAT red to ‘plus’, -BAT black to ‘minus’
8. Once the tests and operation control have been completed, the enclosure can be locked.
