68 ALFOplus 24GHz (North America) - Release 01.05.0x - MN.00395.E - 004
8.2 GENERAL
The ALFOplus radio system is made up of an outdoor unit, protected by a metallic shield.
Compliance to electromagnetic compatibility is guaranteed through the following precautionary measures:
• during the design phase
- use of protection circuits against lightning by means of electrical dischargers
- use of filters on the power supply input circuits against noise propagating on the power supply
wires
• during the installation phase
- use of shielded cables
- use of ground connections.
The installation phases of the whole system are described in the following paraghaphs and it must be done
only by service person suitably trained.
Warning Remember that the whole radio link can work only if ODUs chosen for local and remote side have
equal sub-band and different SSB (H and L).
8.3 ELECTRICAL WIRING
The electrical wiring must be done using appropriate cables thus assuring the equipment responds to the
electromagnetic compatibility standards.
The cable terminates to flying connectors which have to be connected to the corresponding connectors on
the equipment front.
Position and pin-out of the equipment connectors are available in this section.
8.4 CONNECTIONS TO THE SUPPLY MAINS
During the final installation, protect the ODU by a magneto-thermal switch (not supplied with the equip-
ment), whose characteristics must comply with the laws in force in one’s country.
The disconnection from the supply mains is made disconnecting the auxiliary connector M12 5 pin from the
ODU or disconnecting the LAN PoE cable.
The typical magneto thermal switch has characteristics at least 60Vdc @6A with overcurrent relay class
“C” or “K” tripping curve.
Seal the M12 connector when it isn’t used, in order to avoid the removal of the cover without tools (coupling
torque=4Nm).
The operating temperature of power cable must not exceed 60°C.
