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 (~230VAC) to L-N terminals of the PSU. Connect the ground wire to the terminal
marked by the earth symbol
– “
” on the plate. Use a three-core cable (with a yellow and green PE protection
wire) to make the connection. Lead the cables to the appropriate terminals of the connection board through the
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 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.
4. Connect the
receivers’ cables to the terminals of the recorder’s module and the CCTV cameras’ module.
5. If necessary, connect the devices’ wires 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. With the I
BAT
jumpers determine the maximum battery charging current, in accordance with the battery
parameters (see tab.1)
7. With the P
BAT
jumper determine if the discharged battery disconnection system U<10V (+/-5%). shall be on or off.
The battery protection is on when the P
BAT
jumper is removed.
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, AUX1, AUX2 and AUX3. The yellow LB LED should light up while charging.
10
. Check the output voltage (the PSU module voltage without load should amount to 13,6 V÷ 13,9 V, during
battery charging 11V-13,8V). If the value of the voltage requires adjustment, it should be set by the V
ADJ
potentiometer, monitoring the voltage at the AUX output of the PSU.
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. Once the tests and operation control have been completed, the enclosure can be locked.
