Installation.
2.1. Requirements.
The unit should be mounted in confined spaces, in accordance with the 2nd environmental class, with normal
relative humidity (RH=90% maximum, without condensation) and temperature from -
10°C to +45°C. Ensure the free flow
of air around the unit. The PSU shall work in a vertical position that guarantees sufficient convectional air-flow through
ventilating holes of the enclosure.
The switch load balance should be done before installation. The given value of 15,4W per port is the maximum value
referring to a single output. The total power consumption should not exceed 96W 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 in the power supply circuit should be provided. The electrical system shall be made in accordance with
applicable standards and regulations.
2.2. Installation procedure.
1. Connect switch to the PSD480250 48VDC power supply unit desktop type.
2. Connect the power supply to the AC 230V socket.
3. Connect the camera wires to the RJ45 connectors (PoE connectors (sockets RJ45 from 1 to 8).
4. Check the optical indication of switch operation (see Table 3).
