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, cut off the voltage in the 230V power-supply circuit.
2. Mount the PSU in a selected location and lead the connecting cables.
3. Connect the power cables (230V AC) to L-N terminals of the PSU. Connect the ground wire to the terminal
marked with grounding symbol:
. 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
symbol
in the PSU enclosure. 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 power supply line and video signal to the BNC module (See Figure 4):
- connect the supply voltage of the camera to the AUX1÷ AUX8 outputs
- connect the video signals from the cameras and the DVR to the BNC sockets
Figure 4. Connecting the camera and DVR to the BNC module.
5. Use the F1/PTC1 ÷ F8/PTC8 jumpers to select the type of short circuit / overload protection of individual circuits.
Jumper in the Fx position – melting fuse activation, PTCx – PTC fuse activation.
6.
Connect the technical outputs to the control panel or other device:
- FPS technical output of the PSU status – indicates the voltage loss at any of the outputs (AUX1 ÷ AUX8).
- TAMPER indicating enclosure opening.
7. Check the optical indication of the PSU status: green LED light on the BNC module.
8.In case of significant voltage drops on the receivers’ power cables resistance, it is possible to adjust the voltage
with the ADJ potentiometer (12÷15V DC).
9. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication.
3.1. Optical indication.
The PSU has 6 LED lights at the front panel:
