Fiber Active Cabinet (FAC) 900
Installation Manual
_________________________________________________________
Note:
The minimum heights assume a distance of 15.25 inches above the ground to the top of the base platform. To
elevate the cabinet higher than 15.25 inches above ground, use a wall or H-frame with sufficient additional height.
•
Use the Clearfield wall/H-frame mount kit to provide the mounting fixture and conduit entry locations.
•
The Clearfield wall/H-frame mount kit provides assembly hardware for a wall or wooden H-frame, however
you must
provide the hardware
to attach the mounting fixture, as appropriate for your site requirements. For example, attach
-
ing the fixture to a concrete wall requires different hardware (anchors). Follow local codes and practices to supply the
required mounting hardware.
•
Use 4-inch conduit (maximum) for outside plant cables. See figure for entry locations.
•
Use 2.5-inch conduit (maximum) for AC cable. See figure for entry location.
• Include pull cords in all cable conduits.
•
For H-frames, Clearfield recommends the following
nominal
beam sizes, as required for the cabinet mounting configura
-
tion:
•
Low profile configurations:
Two 6" x 6" x 8.5' vertical beams, or two 8" x 8" x 8.5' vertical beams for seismically
active areas
•
High profile configurations:
Two 6" x 6" x 9.4' vertical beams, or two 8" x 8" x 9.4' vertical beams for seismically
active areas
•
(FAC 900 + EXM) Both low and high profile configurations:
One 2" x 8" x 8.0' horizontal beams on the top and
two 2" x 8" x 8.0' horizontal beams on the bottom to support the fixture
Note:
To use the supplied hardware, do not exceed the nominal size for the horizontal beams. A nominal size of 2" x 8"
x 8.0' correlates to an actual size of 1.5" x 7.25" x 8.0'.
•
(FAC 900 only) Both low and high profile configurations:
One 2" x 8" x 5.6' horizontal beams on the top and two
2" x 8" x 5.6' horizontal beams on the bottom to support the fixture
Preparing the Site
Prepare the site for installation of a wall/H-frame mount kit. A general practice is described below for reference. Adapt the
instructions as needed for local requirements, practices, or conditions.
To prepare the site for a wall/H-frame mount installation
Step 1:
Step 2:
Step 3:
At the installation site, verify the following:
• The wall or H-frame is installed and plumb.
• The wall or H-frame meets the cabinet mounting
requirements
.
Trench out conduit paths to the wall or H-frame from the cable feeder location. Place the cable conduits into
the conduit trench. At the wall or H-frame, allow the conduit to extend above ground to the approximate height
of the base platform. Refer to the
wall mounting guidelines
and
drawings
for conduit locations.
Route the earth ground wire through the conduit trench (from the ground electrode). Pull six feet of wire above
ground and position it adjacent to the wall or H-frame. Backfill the conduit trench with soil.
