2.3.4 Installing the L-867B
Base
To install the base, perform the following procedure:
1. Install the L-867B per the site plans and specifications. See FAA AC 150/5340-30 for
additional installation instructions.
2. Orient the cable entrance hubs of the base in the proper directions.
3. Level the light base so that the mounting flange surface is flush with the finished grade.
4. With the light base at proper orientation and held at proper elevation, pour concrete
around the outside of the base. If the base is installed outside the concrete pad, backfill
with compacted earth.
5. Slope top of concrete away from the flange portion of the base.
6. In closed duct systems installed in soil conditions of good drainage, use light bases
having a drain hole to prevent water accumulation.
7. Pull field cable and connect the L-830, if specified, in the light base.
8. Install the base plate w/gasket on top of the light base. The baseplate is designed to
receive the RGL frangible coupling using a female thread.
2.3.5 Installing on a L-867B
Base
To install the L-804, perform the following procedure:
1. If using the current driven L-804, install the L-804 RGL assembly and frangible column,
and connect the L-823 cordset supplied with the RGL to an L-830, 100 W/6.6 A isolation
transformer. See Figure 9 in the Wiring Schematics section for wiring connections for
current driven monitored and unmonitored versions.
If using the voltage driven L-804, install the L-804 RGL assembly and frangible column,
and connect the L-823 cordset supplied with the RGL to 120 or 220-240 Vac input. See
Figure 10 and Figure 11 in the Wiring Schematics section for wiring connections for
voltage driven monitored and unmonitored versions.
If using the Direct Lamp Access L-804, install the L-804 assembly and frangible column,
and connect the L-823 cordsets supplied with the RGL to the two BRITE outputs. The
connection order is not important. See Figure 12 in the Wiring Schematics section for
wiring connections for the Direct Lamp Access versions.
2. Bolt the base plate to the light base.
NOTE: Only use two of the mounting bolts at this time and only hand tighten these bolts.
After horizontal aiming has been completed and verified, install the remaining baseplate
bolts and then torque bolts to 180 – 190 In-Lbs.
3. Aim the L-804 RGL both vertically and horizontally per site plans and specifications.
Aiming procedure is as follows:
