2.3.4.1 Installation on L-868
Base
The light assembly is shipped complete, and is ready for installation.
To install the fixture on an L-868 base, see FAA AC 150/5345-30 and the project site-specific
plans and specifications for details on L-868 base installation.
NOTE:
Mounting bolts are not supplied with the fixture. Mounting bolts and anti-rotation lock
washers are normally supplied with the base can spacer or flange ring. If a flange ring is used,
the bolt length is 1-1/4 inch (32mm) plus the thickness of the flange ring.
Also read the following guidelines:
1. Clean the base receptacle. Make sure the base receptacle is completely clean and dry.
The mating surfaces must be clean and free of foreign particles.
2. Fit an appropriate lifting tool into the two threaded holes, which are located 180° apart in
the cover.
NOTE:
The lifting tool can be made from two 1/2 x 13 eyebolts (1-inch ID) and a 1/2-inch
diameter, 16-inch (406mm) long rod or pipe inserted through the eyebolts.
3. Carry the light assembly to the base.
4. Place the light assembly beside the opening in the L-868 base so that the L-823 connector
can be connected with the mating receptacle from the L-830 or L-831 isolation transformer
in the base. Make sure that the connection is solid and secure. Refer to “Electrical Supply
” on page 7 for required isolation transformers.
NOTE:
Make sure items such as spacers, shims and gaskets are installed on the light
base as indicated on site plans, specifications and drawings.
5. Position the light assembly over the L-868 base and set it onto the base. Align the light
according to FAA AC 150/5345-30 and project plans and specifications. Remove the
eyebolts and lifting rod.
6. Attach the six fixing bolts and anti-vibration washers.
7. Turn on the power to determine whether the LED fixture will illuminate. Operate for a
minimum of five minutes.
8. See “Torquing and Installation Guidance for In-pavement Fixtures” on page 17.
CAUTION
Never hold the light fixture by the wires. Doing so may damage the
insulation, break the waterproof seal and cause insulation faults and water
leakage.
WARNING
Ensure that the cord set wires are NOT pinched between the base can and
the fixture. Pinched wires can cause water to be drawn inside the fixture.
WARNING
Due to the risk of bolts vibrating loose, do not use any type of washer with
the fixing bolts (such as split lock washers) other than an anti-vibration
washer. Anti-vibration washers identified as CEC or Nord-Lock
®
or
equivalent must be used. Nord-Lock part number NL-3/8-SS is
recommended for replacement applications.
