2.3

The EDC will hold up to three Type 2R

0.2-inch high or two Type 4R 0.4-inch high
reduced length splice trays (ordered separately).

2.4

The unit can be field connectorized using

Corning Cable Systems 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 (purchased separately).

2.6

The unit may be pad-locked with a user-

supplied padlock after installation of the
provided quick-release latch kit.

2.7

Factory stubbed units are available with a

preconnectorized length of fiber optic cable
installed and strain-relieved inside the unit.

Precautions

3.1

Laser Handling Precautions

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

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.

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.

CAUTION: 

The filling compound remover

used to clean loose-tube cable contains petroleum
distillates which are harmful or fatal if swallowed.
DO NOT induce vomiting. Call physician
immediately.

3.3

Glass Fiber Precautions

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.

3.4

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 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.
