General
1.1 This instruction describes recommended
procedure for the installation of the six-panel
Environmental Distribution Center (EDC)
(p/n EDC-06P-NH) manufactured by Corning
Cable Systems.
p/n 003-545
Description
2.1 The EDC that stores and protects fiber
optic connections and splices in an outdoor
environment. The cabinet carries a NEMA 250
Type 4X and Type 13 rating in addition to a
IEC 529 IP66 rating. The unit provides
environmental protection and strain-relief for
one distribution cable and up to six drop cables.
2.2 Connector panels are used to provide
interconnection between the distribution and
drop cables. The EDC accommodates up to six
LANscape® connector panels. Colored icons are
available with different symbols for a quick
visual reference of the data type at each
connector location. Panels and connector panel
icons are ordered separately.
2.3 The unit accommodates six Type 2S or
three Type 4S splice trays that protect
mechanical or fusion splices. Splice trays are
ordered separately.
2.4 The unit can be field connectorized using
buffer tube fan-out (BTF) kits, which are
ordered separately.
2.5 The EDC comes with brackets to mount
the unit to a wall or a standard utility pole. The
unit may be rack-mounted with an optional
rack-mount kit.

2.6 The unit may be padlocked with a user
supplied padlock after installation of the
provided quick-release latch kit.
WARNING: Cleaved glass fibers are very
sharp and can pierce the skin easily. Do not let cut
pieces of fiber stick to your clothing or drop in the work
area where they can cause injury later. Use tweezers to
pick up cut or broken pieces of the glass fibers and place
them on a loop of tape kept for that purpose alone.
Good housekeeping is very important.
2.7 Factory stubbed units are available with a
specific length of preconnectorized cable
installed and strain-relieved in the unit.
3.
Precautions
3.1
Laser Handling Precautions
3.4
WARNING: Never look directly into the
end of a fiber that may be carrying laser light.
Laser light may be invisible and can damage your eyes.
Viewing it directly does not cause pain. The iris of the
eye will not close involuntarily as when viewing a
bright light. Consequently, serious damage to the
retina of the eye is possible. Should accidental eye
exposure to laser light be suspected, arrange for an eye
examination immediately.
WARNING: DO NOT use magnifiers in the
presence of laser radiation. Diffused laser light can
cause eye damage if focused with optical instruments.
Should accidental eye exposure be suspected, arrange
for an eye exam immediately.
3.2
CAUTION: The wearing of safety gloves to
protect hands from accidental injury is strongly
recommended when using sharp instruments.
CAUTION: Isopropyl alcohol is flammable
with a flashpoint at 50°F. It can cause irritation to
eyes on contact. In case of eye contact, flush eyes with
water for at least 15 minutes. Inhaling fumes may
induce mild narcosis. In case of ingestion, consult a
physician.
Cable Handling Precautions
NOTE: Fiber optic cable is sensitive to excessive
pulling, bending and crushing forces. Consult the cable
specification sheet for the cable you are installing. Do
not bend the cable more sharply than the
minimum recommended bend radius. Do not
apply more pulling force to the cable than
specified. Do not crush the cable or allow it to
kink. Doing so may cause damage that can alter the
transmission characteristics of the cable — the cable
may have to be replaced.
3.5
Installer Precautions
WARNING: Do not install this unit or work
with telephone wiring during a lightning storm.
Telephone lines can carry high voltages from lightning
causing electrical shock resulting in severe injury or
death.
Safety Precautions
CAUTION: The wearing of safety glasses to
protect the eyes from accidental injury is strongly
recommended when handling chemicals and cutting
fiber. Pieces of glass fiber are very sharp and can
damage the cornea easily.

Preparing Cable
9.1 Route the incoming distribution (feeder)
cable through the fitting on the left at the base
of the unit.
9.2 Perform cable sheath removal steps per
instructions for the type of cable being
installed. Cut the cable to 3 meters (10 feet)
inside the unit.
NOTE: Do not expose the bare fiber until you are
ready to terminate it.
1) Wrap a section of clamp material around
the cable to determine the length needed
for one full wrap.
2) Use side cutters to cut the clamp material
so that it ends up one section shorter than
this length.
3) Place the cut length of clamp material 5 cm
(2 inch) from the end of the cable sheath.
4) Install a hose clamp over it, covering as
many holes as possible. Hand tighten with a
slotted screwdriver or a 5/16-inch driver.
5) Wrap the sheath retention assembly with
vinyl tape. (Shown without vinyl tape for

CAUTION: The connector is a delicate device.
Obey the following precautions. Damage to the
surface of the connector will make it unusable:
•
Use a clean tissue soaked in alcohol to
gently clean the connector. Do not press
heavily on it as you clean.
•
Dry the connector prior to installation with
compressed air or a dry tissue.
•
Clean all areas that will contact the
connector adapter.
•
Do not force the connector into the
receptacle. If the connector does not fit
easily into the receptacle, back it out and
reinstall.
•
Install threaded connectors into the adapter
and tighten. Do not OVERTIGHTEN. Do
not allow the connector body (ferrule) to
turn as you screw it into place. This causes
the surfaces to grind against each other.
10.5 Remove the blank connector panels from
the unit (Figure 15). Install the loaded
connector panels into the connector support
bracket (Figure 16).
11. Splicing
11.1 The unterminated ends of pigtails are
spliced to buffered fibers in a splice tray
(Figure 14). Prepare the buffer tubes for
splicing.
a) Route three complete loops of fiber around
the radius guides in a counterclockwise
direction. The radius guides are divided into
three sections. Begin routing from the back
section and work your way forward with
each loop in a different section of the guide.
b) Reinstall the splice tray holder and install
one of the splice trays you will be using.
c) Place ALL the buffer tubes as they will lie
after installation and mark the cable 2 cm
(3/4 inch) from where it will enter the corner
of the splice tray as shown in Figure 17.
(This is where the buffer tube will be
removed.)
d) Refer to the instructions provided with the
splice tray to determine the appropriate
length of fiber required in the tray. Measure
from the first mark toward the end of the
buffer tubes and mark the buffer tubes.
e) Trim the excess buffer tube beyond the
second mark.
10.6 Repeat for all required panels.
Plunger
f) Remove the splice tray and the coiled buffer
tubes.
Pull the plunger fastener
out all the way so that
the fingers collapse.
Housing
Position the fastener into
the mounting holes in
the housing.
g) Remove the buffer tubes to the marked
point (plus the length needed inside the
tray). Strip and clean the fibers according to
the cable manufacturer’s instructions.
Fingers
Push the plunger in to
expand the fingers and
lock the unit to the housing.
To remove the unit, pull the plungers out.

11.2 Prepare the pigtail for splicing in the same
manner.
11.3 Work on one splice tray at a time. Bring
both pigtails and buffered fibers to a convenient
splicing area - one pair at a time. Secure these
fibers to the same corner of the splice tray.
11.7 Place the spliced trays into the holder as
shown in Figure 19. The fibers exiting the trays
are positioned around the radius control guide.
Secure the trays to the holder using the
provided hook-and-loop strap.
IMPORTANT: When securing 900 µm fiber to
the splice tray, 1.5 inches of electrical tape around
the sheath as protection for the 900 µm fiber is
recommended. Feed a cable tie through the strainrelief holes in the corner of the splice tray. Carefully
tighten the cable tie around the tape-wrapped
portion of the fibers to secure the fibers to the tray.
DO NOT tighten the cable tie too tightly.
11.4 Splice fibers as described in instructions
for the splicing method you are using.
11.5 As you complete a splice, label the
connector end of the pigtail with its port
identifier. Record information appropriately on
the record label inside the front door
(Figure 18).
11.6 Repeat for all required splice trays.
Figure 19
11.8 Once all splicing is complete, route all
buffer tubes (beginning at the cable sheath
opening) and pigtails (starting at the connector
panels) counterclockwise around the radius
guides (Figure 20).
Figure 18
NOTE: Accurate record keeping is imperative for
an organized installation.
Figure 20
Page 10
SRP-003-545 • Issue 4 • July 2004
a) Place pigtails on the outside of the loops
and the buffer tubes closest to the guides.
b) Make sure the fiber from the connector
boot is not pulled too tightly and the bend
radius is not violated.
c) The first loop should be in the back section
of the radius guides and each successive loop
should be in the section above the previous
loop.
12. Installing Fan-outs
12.1 Fiber optic cable can be installed using
BTF kits (ordered separately).
12.2 Slide the splice tray holder toward the top
of the housing and remove it. Remove the splice
tray holder mounting bracket also (Figure 22).
(The fan-out bracket is underneath it.)
d) At the third loop, reinstall the splice tray
holder and trays (Figure 21).
NOTE: Cable ties can be loosely attached to
organize the coils of buffer tubes and pigtail
assemblies.

12.5 Route the buffer tubes around the radius
guides and secure the fan-out assemblies to the
fan-out bracket as shown using a cable tie
(Figure 24).
NOTE: The splice tray holder and its mounting
bracket should be reinstalled to allow future splicing
capabilities.
13. Installing Drop Cable
13.1 The EDC is designed to accept up to six
drop cables. Feed 3 meters (10 feet) of drop
cable through the fitting you installed on the
right at the base of the closure.
1) Route three complete loops of the subunit
around the radius guides (Figure 28).
2) Match the subunits to the corresponding
panels and simulate how they will lie.
3) Mark the length on the subunit and trim the
cable to this length.
13.2 Gently secure cable with no central
members to the bracket using cable ties.
