2. Installation
2.1. Requirements
1. The device should be mounted by a qualified installer, holding relevant permits and licenses (applicable and required
for a given country) for 230 V and low-voltage installations. It is required to install an installation switch with a nominal
current of min. 3 A in the power supply circuits outside the power supply unit.
2. The device shall be mounted in confined spaces, according to the environment class II, with normal air humidity
(RH=90% max. without condensation) and the temperature from -
10°C to +40°C.
3. The switch shall work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of
the enclosure. 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.
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. 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). 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 power (230 V).
5. Connect the camera cables to the RJ45 connectors (PoE connectors).
6. Check the optical indication of the switch operation.
7. After installing and checking proper working, the enclosure can be closed.
