The given value of 30 W per port is the maximum value. The total power consumption should not exceed 60 W.
2. 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 -
30°C to +70°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. Depending on application, appropriate power supply should
be selected, PoE available only at 48-57 V (52 V recommended). The given value of 30 W per port is the maximum value
referring to a single output. The total power consumption should not exceed 60 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 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 power supply unit(s), paying attention to polarization and other parameters.
2. Connect the power supply(s) to the 230 V socket.
3. Connect the camera wires to the RJ45 connectors (sockets RJ45).
4. Check the optical indication of switch operation (see Table 3).
