INSTALLATION INSTRUCTIONS
3.1
FIXTURE INSTALLATION
Three different installation modalities are provided for LEA lights.
Direct installation on the breakable coupling, normally for threshold, threshold wing bar and
runway end lighting. In this case the fixture is supplied completely assembled with breakable
coupling and FAA L-823 plug.
Figure 4: direct mounting
On the top of a supporting pole with breakable coupling, normally for approach (centreline and
crossbars), approach side row barrettes and stop bars.
In this case the fixture is supplied without supporting pole and breakable coupling, which must be
ordered separately.
The aluminum pole, dia 60 mm, is available of length not exceeding 2 m (four standard lengths
are available: 50 cm - 1 m - 1.5 m - 2 m) and must be on-site cut at the proper length depending
on the approach profile design.
The fixture can be supplied assembled complete with FAA L-823 plug (two-single pole wires, 50
cm long), and grounding wire for installation on poles of length not exceeding 30 cm, or semi-
assembled, that is two-pole cable lead with FAA L-823 plug, 2.50 m long, not wired to the fixture.
The cable lead must be on-site cut at the proper length and then wired to the fixture by means of
the special bulkhead connector.
NOTE: the fixture must not be opened to wire the cable lead with FAA L-823 plug.
