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 network cables (Ethernet) to the PoE module:supply voltage is present only at the PoE sockets and
the cameras should be connected to them. Connection diagram is shown in Figure 4:
Fig. 4. Connection of cameras and network devices to the LAN and PoE terminals.
5. In case of significant voltage drops on the receivers’ power cables resistance, it is possible to adjust the voltage
with the V
ADJ
potentiometer
(46÷52V DC).
6. Check the optical indication of the PSU status.
7. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication.
The presence of voltage at the input of PoE modules is indicated by LEDs on the front panel.
4. Service and operation.
4.1. Activation of the overload protection of the power supply unit.
When the OVP system is activated, the output voltage is automatically cut off. Restart is possible after
disconnecting the PSU from the mains supply 230V for at least 20 seconds.
4.2. Activation of the OVP system of the PSU
When the OVP system is activated, the output voltage is automatically cut off. Restart is possible after
disconnecting the PSU from the mains supply 230V for at least 20 seconds.
4.3. Maintenance.
All maintenance procedures can be performed after disconnecting the power supply from the power
network. The PSU does not require any specific maintenance; however, its interior should be cleaned with
compressed air if used in dusty conditions.
