The power supply is designed for a continuous operation and is not equipped with a power-switch.
Therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the user should
be informed how to disconnect the power supply unit from the mains supply (usually by assigning an appropriate fuse in
the fuse box). The electrical system shall be made in accordance with applicable 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. The tamper bracket, located in the central part of the housing (see
Fig. 3 [3]), signaling the attempts to detach the PSU from the mounting surface, should be screwed to the
mounting surface.
Fig. 4. Mounting the tamper bracket.
3. Connect the power cables (230V AC) to the L-N terminals of the PSU. Connect the ground wire to the
terminal marked with the PE symbol (power supply module connector). Use a three-core cable (with a
yellow and green PE protection wire) to make the connection. The power cables should be connected to
the appropriate terminals on the connection board through the bushing.
The shock protection circuit shall be done with a particular care: the yellow and green
wire coat of the power cable should be connected to the terminal marked with
the PE symbol. Operation of the PSU without the properly made and fully operational
shock protection circuit is UNACCEPTABLE! It can cause damage to the equipment or
an electric shock
4. Connect the receiver cables to the AUX terminals at the power supply board.
5. 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
- Optional installation of the MPSBS relay module changing technical outputs of the OC type to relay type
(page 9, section. 3.3)
6. Use the I
BAT
jumper to set the maximum battery charging current, taking into account the battery
parameters.
7. Use the P
BAT
jumper to set to turn on/off deep discharge battery protection U<20V (+/-5%).
Deep
discharge battery protection is ON when the P
BAT
jumper is OFF.
8. Mount the battery in the battery compartment of the enclosure (Fig. 3). Connect the batteries with the PSU
paying special attention to the correct polarity.
9. Switch on the 230V AC supply. The corresponding LEDs on the power supply PCB should be ON: red AC
and green AUX. The yellow LB LED should light up while charging.
10. Check the output voltage (the power supply voltage without load should be 27,2
V ÷ 27,8V, 22V ÷ 27,6V
while battery charging). If the voltage requires adjustment, use the V
ADJ
, potentiometer while monitoring the
voltage at the AUX output of the power supply.
11. Check the current consumption of the receivers, taking into account the battery charging current, so as not
to exceed the total current efficiency of the PSU (section 1.1).
12. Close the cover after installing and checking the operation of the power supply.
