1. Technical description.
1.1. General description.
The PSU is designed for supply of up to 8 cameras IP requiring stabilized voltage of 48V DC.The output
voltage can be adjusted with a potentiometer between 46V÷52V DC. The power is carried over the spare pairs (4/5 &
7/8), which, according to the Ethernet network standard, are not used for data transmission (data transmission
uses 1/2 and 3/6 data pairs). The PSU is housed in a metal enclosure with signaling panel equipped with a
microswitch indicating door opening (front cover).
The PSU can not be used in Gigabit Ethernet networks, where all twisted pairs are involved in the
transmission of data!

2. Installation.
2.1.Requirements.
The buffer PSU should 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 2nd environmental class, with normal relative humidity
(RH=90% maximum, no condensation) and temperature range from -10°C up to +40°C. The power supply should
operate in a vertical position in order to provide free and convectional air flow through ventilating holes of the
enclosure.
During normal operation, the total current drawn by the device should not exceed I=2,8A.
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.
The PSU is designed for 10Mbit/s and 100Mbit/s Ethernet network (so-called Fast Ethernet). However, it
can not be used for a 1000 Mbit/s network (so-called Gigabit Ethernet). Connections between the power
supply and the camera can be done using UTP-3 cable (networks with data-rates up to 10 Mbit/s) or UTP-5 cable.
Due to the lower resistance wiring, it is recommended (especially at large distances between the power supply and
receivers) to use UTP-5 cable also for networks with data-rates up to 10 Mbit/s.

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 VADJ 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.
