Configuration and assembling
The fixtures LERA are supplied in different configurations depending on the assembly mode provided for the device:
●
Direct assembly: the fixtures are complete with frangible coupling (configuration/assembling: P-001). The
body is directly installed on the coupling that is fastened to the anchorage (threading 2” GAS). The fixture
in this configuration is completely assembled, with bipolar plug FAA L-823 Style
●
Mounting on pole with frangible coupling: the fixtures are supplied without pole and without coupling
(configuration: C). Depending on the configuration the fixtures can be supplied in the following configurations:
000: fixture without power cable, suitable for the mounting on pole with frangible coupling. The bulkhead
connector installed on the body of the fixture is equipped with connector which allows the connection to
be made without opening the fixture. The parts required for assembly (bipolar cable and connector kit
FAA L-823 Style 5, pole Ø 60 mm and frangible coupling) must be ordered separately. For further details,
please refer to the mounting accessories table.
050: fixture already assembled, complete with power supply cable (two unipolar conductors L = 500 mm
with plug FAA L823 Style 4) and ground cable, suitable for the mounting on pole with frangible coupling
of maximum height 300 mm. The parts required for assembly (pole Ø 60 mm and frangible coupling)
must be ordered separately. For further details, please refer to the mounting accessories table.
250: fixture semi-assembled, complete with power supply cable (bipolar cable L = 2500 mm) equipped with
plug FAA L-823 Style 1 and ground cable, suitable for the mounting on pole with frangible coupling. The
cable is supplied separately: it is possible to cut the cable to length and proceed to assembly. The bulkhead
connector installed on the body of the fixture is equipped with connector which allows the connection
to be made without opening the fixture. The parts required for assembly (pole Ø 60 mm and frangible
coupling) must be ordered separately. For further details, please refer to the mounting accessories table.
The threshold, wing bars and runway end use fixtures are normally mounted on the frangible
coupling (configuration/assembly: P-001).
Axis fixtures and approach bars are normally mounted on a pole with a frangible coupling
(configuration: C | NOTE: actual pole length fixed by the installation project!).
The approach bars, side approach bars fixtures are normally mounted on folding poles
(configuration: C | NOTE: actual pole length fixed by the installation project!).
