Before installation, prepare a Switch'a load balance.
The given value of 30 W per port is the maximum value referring to a single output. The total power consumption
should not exceed 48 W when all PoE ports are being used
. The increased demand for power is particularly evident in the
case of cameras with heaters or infrared illuminators - when launching these features, the power consumption increases rapidly,
which may adversely affect the operation of the switch. As the device is designed for a continuous operation and is not
equipped with a power-switch, therefore an appropriate overload protection shall be guaranteed in the power supply circuit.
Moreover, the user shall be informed about the method of unplugging (usually through assigning an appropriate fuse in the fuse-
box). The electrical system shall follow valid standards and regulations.
2.2. Long Range mode
Switch enables operation in two modes: standard and extended range. When the Long Range switch is in
STANDARD position (see Fig. 5), PoE ports operate at 100 Mb / s up to 100 meters. After switching to EXTEND position,
range is increased to 250 meters and speed is reduced to 10 Mb / s. Additionally, VLAN function, which isolates the PoE
ports between each other (communication takes place between the UpLink ports and individual PoE), is activated. In both
modes, the UpLink port speed is 100 Mb / s.
Note:
Changing the modes requires a power restart!
2.3. Installation procedure
Before installation, cut off the voltage in the 230 V power-supply circuit.
To switch power off, use an external switch, in which the distance between the contacts of all
poles in the disconnection state is not less than 3mm.
1. Mount the PSU in a selected location and connect the wires.
2. Connect the power cables (230 V) to L-N clips of the PSU.
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 ‘
‘
symbol on the PSU enclosure. Operation of the PSU without the properly made and fully
operational shock protection circuit is UNACCEPTABLE! It can cause a device failure or
an electric shock.
3. Connect the ground wire to the terminal marked with the symbol (power supply module connector). Connect the
ground wire to the clip marked by the earth symbol
. Use a three-core cable (with a yellow and green
protection
wire) to make the connection. Lead the cables to the appropriate clips through the insulating bushing of the connection
board.
4. Connect the battery (mind the colours):
- battery output (+V): BAT+ cable / red,
- battery output (0V): BAT
– cable / GND / black.
5. Connect the power (230 V).
6. Connect the camera cables to the RJ45 connectors (PoE connectors) and connect the recorder to the network (the
UP LINK connector).
7. Connect the power supply of the DVR (by default, the device is equipped with a cable terminated with the DC 2.1 / 5.5
plug).
8. Check the optical indication of the switch operation.
9. After installing and checking proper working, the enclosure can be closed.
