3. PRECAUTIONS
3.1. Laser Handling Precautions
WARNING: Never look directly into the end of a ber that may be carrying laser light.
Laser light can 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 magniers in the presence of laser radiation. Diffused laser light
can cause eye damage if focused with optical instruments. Should accidental eye exposure to
laser light be suspected, arrange for an eye examination immediately.
3.2. Safety Precautions
WARNING: Isopropyl alcohol is ammable with a ashpoint at 54ºF. It can cause irritation to
eyes on contact. In case of contact, ush eyes with water for at least 15 minutes. Inhalation
of vapors irritates the respiratory tract. Exposure to high concentrations has a narcotic effect,
producing symptoms of dizziness, drowsiness, headache, staggering, unconsciousness and
possibly death.
CAUTION: Recommend the use of safety glasses (spectacles) conforming to ANSI Z87, for
eye protection from accidental injury when handling chemicals, cables, or working with ber.
Pieces of glass ber are very sharp and have the potential to damage the eye.
CAUTION: The wearing of cut-resistant safety gloves to protect your hands from accidental
injury when using sharp-bladed tools and armored cable is strongly recommended. Use
extreme care when working with severed armor. There will be a sharp edge where armor is
cut. To minimize the chance of injury from the cut armor, cover the exposed edge with a wrap
of electrical tape. To minimize the chance of injury from sharp-bladed tools, always cut away
from yourself and others. Dispose of used blades and armor scrap properly.
3.3. Glass Fiber Precautions
CAUTION: Cleaved or broken glass bers are very sharp and can pierce the skin easily.
Do not let these pieces of ber stick to your clothing or drop in the work area where they can
cause injury later. Use tweezers to pick up cleaved or broken pieces of glass bers and place
them on a loop of tape kept for that purpose alone. Good housekeeping is very important.
3.4. Cable Handling Precautions
CAUTION: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces.
Consult the cable specication 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 specied. 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.

STANDARD RECOMMENDED PROCEDURE 003-333 | ISSUE 9 | MARCH 2012 | PAGE 3 OF 6
3.5. Lifting Precautions
CAUTION: The Optical Splice Enclosure weighs over
50 pounds. Two people are required to move or lift it into
position.
4. MOUNTING
The enclosure ships with the mounting brackets attached in the location shown to mount the enclosure:
• on the wall,
• onto T-slot rails
• or into a 23-inch utility rack with frontal projection.
4.1. Wall-Mounting
IMPORTANT: Make sure there is adequate space above
and below the unit to route cables. Do not
violate the minimum bend radius for any
cable being installed. If you are installing a
pass-through kit, maintain between 0.8 to
2 inches between the two units.
Step 1: Choose a dry, vertical surface on
which to mount the cabinet. The type
of hardware used is dependent on
the mounting location; wall anchors
may be required for adequate support
on sheetrock walls. Wall-mounting
hardware is not provided.
Step 2: Using the mounting template provided,
mark the locations for the six mounting
screws.
Step 3: Leaving a 1/8-inch gap behind the
screw head, install the two top mounting screws in the wall using the distances shown.
Step 4: Hang the unit on the two screws through the upper holes in the mounting brackets. Tighten
the screws against the brackets.
Step 5: Install the remaining screws in the lower holes in the brackets and tighten securely.
4.2. T-Slot Mounting
T-slot rack mounting kits are purchased separately. Refer to the Accessories section of this instruction
for part number information. Follow the instructions provided with the kit.

4.3. Rack-Mounting with Front
IMPORTANT: Make sure there is adequate space above and
below the unit to route cables. Do not violate
the minimum bend radius for any cable being
installed. If you are installing a pass-through kit,
maintain between 0.8 to 2 inches between the two
units.
Determine the location of the enclosure in the utility rack.
If mounting the cabinet into the 23-inch rack with frontal
projection, use the two OSE mounting brackets as they
were factory-installed on each side of the cabinet.
(OPTIONAL: Recessed Mounting) If mounting the
cabinet into the 23-inch rack with recessed projection,
remove the mounting brackets and reattach them in the
alternate location shown.
Step 1: Insert two screws in the top two position on
either side of the 23-inch rack where the OSE
bracket is to be mounted.
Step 2: Leave a 1/8-inch gap between the rack and the
screw head to hang the unit.
Step 3: Lift the cabinet into position on the rack and
hang the cabinet on these bolts through
the upper holes in the mounting brackets.
Tighten the screws against the brackets.
Step 4: Install the lower mounting screws and tighten
them against the mounting brackets.
5. GROUNDING
Locate the external ground locations shown. Ground
unit per local practices.
6. CABLE PREPARATION
NOTE: Cable-entry hardware kits are purchased separately.
Follow the instructions provided with the
kit. Select the appropriate cable-entry
hardware for the cable being installed.
• OSE-CBL-34 through -39: Liquid-tight
cord connectors for most cable types.
Includes central member strain-relief
capability.
• OSE-A288-SCR-36 or -38: Liquid-
tight cord connectors for cut cable
applications and split grommet for mid-
span applications. Includes one breakout
tray. No central member strain-relief
capability.

• OSE-A288-MSPN-KIT: Split grommet for mid-span applications. Includes central member strain-
relief capability.
Step 1: Determine cable entry location and remove the required knockouts. Start at the rear corner
and work toward the front and center.
Step 2: Strain-relieve the cable as detailed in the instruction provided with the cable-entry hardware
kit.
Step 3: Remove cable sheath as described in the sheath removal instructions for the cable you
are installing. Suggested lengths shown here can be altered for particular preferences or
specic applications.
• If you are installing cable with multiple buffer tubes that will be looped in the enclosure, use a mid-
span access kit (p/n OSE-A288-MSPN-KIT, purchased separately) to access the ber in one buffer
tube without disturbing the other buffer tubes.
• If you are installing ribbon cable or cable with single tube construction that will be looped in the
enclosure, use a breakout kit (p/n OSE-A288-SCR-36 and -38, purchased separately). The
breakout kit contains grommets and strain-relief hardware.
Step 4: Ground armored cable as illustrated in the instruction provided with the cable-entry
hardware kit. Additional ground kits (p/n HDWR-GRND-KIT) may be purchased separately.)
7. ROUTING CABLE WITH MULTIPLE BUFFER TUBES
NOTE: An optional workshelf kit (purchased separately) is available to provide a larger work surface. Refer
to Section 2 for part number information. Follow the instructions provided with the kit.
Step 1: Place a splice tray in the bottom position in the splice tray stacker assembly.

Step 2: Route at least one full loop of buffer tubes in a clockwise direction around the radius guides,
through the routing clips, and into the splice trays as shown. Note that the cable can enter
from the top or bottom of the cabinet. Do not bend cable too sharply.
NOTE: Use cable ties every 10-12 inches to bundle buffer tubes. Do not overtighten cable ties.
Step 3: Mark buffer tubes where they will enter the splice tray.
8. SPLICING
Step 1: Bring splice tray and ber to splice tray shelf.
Step 2: Strip buffer tubes at the mark made in Section 7.
Step 3: Secure buffer tubes to splice trays. Splice bers as explained in the instructions provided
with the try and for the splicing method you are using.
Step 4: Once splicing is complete, load the splice tray into the stacker, beginning at the bottom.
Step 5: Secure all trays using the provided hook-and-loop strap.
NOTE: A Slotted Core Ribbon kit (purchased separately) is required for installation of slotted core ribbon
cable. Refer to Section 2 for part number information. Follow the instructions provided with the kit.
Step 6: Conrm cable does not violate minimum bend radius before securing exterior door.
