2. Installation.
2.1. Requirements.
The buffer PSU module 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 II-nd environmental class, with normal relative humidity (RH=90% maximum,
without condensing) and temperature from -
10°C to +40°C.
The unit should be mounted in a metal enclosure (cabinet) in a vertical position so as to ensure free, convection
air flow through the vents.
In order to meet the EU requirements, follow the guidelines on: power supply, enclosures and shielding:
- according to application. The module requires 30-32V AC power supply with galvanic. (transformer) isolation.
1. Output current 1A (without battery)
2. Output current 0,8A + 0,2A battery charge
3. Output current 0,5A + 0,5A battery charge
Total device c battery: 1A max.
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, cut off the voltage in the 230V power-supply circuit.
2. Install the enclosure or cabinet and lead the cables through the cable ducts.
3. Install the PSU module on mounting pins (the mounting pins should be installed before the assembly of the
enclosure/cabinet).
4. Deliver the AC voltage to the ~AC~ terminals.
5. Connect the
receivers’ cables to the +AUX, -AUX terminals of the terminal box on the PSU board.
6. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- PSU; technical output indicating PSU failure.
- LoB; technical output indicating low battery voltage
7. Using the I
BAT
pins, determine the maximum battery charging current the should be determine, in accordance
with battery parameters.
8. Using the P
BAT
pins, determine whether the function of disconnecting the discharged battery U<20V (+/-5%) is to
be on or off.
The battery protection is on
if the P
BAT
jumper is removed.
9. Make the connections between the battery and the power supply panel paying special attention to the correct
polarity.
