* The given value of 30 W per port is the maximum value. The total power consumption should not exceed 96 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 -10 °C to +40 °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 30 W per port is the maximum value referring to
a single output. The total power consumption should not exceed 96 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 PSD520230 52 V DC power supply unit desktop typ
2. Connect power supply to 230 V socket
3. Connect camera wires to RJ45 connectors (PoE connectors (sockets RJ45 from 1 to 8)
4. Connect remain devices LAN to RJ45(G1/TP and G2/TP) connectors and SFP(G3/SFP and G4/SFP) sockets
5. Check optical indication of switch operation (see Table 3).
