3. preCAutions
3.1. Laser Handling precautions
WArninG: Never look directly into the end of a fiber 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 magnifiers 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 flammable with a flashpoint at 54ºF. It can cause irritation to eyes on contact. In case of contact, flush 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 fiber.
Pieces of glass fiber 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 fibers are very sharp and can pierce the skin easily.
Do not let these pieces of fiber 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 fibers 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 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. 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: Liquidtight cord connectors for cut cable applications and split grommet for midspan applications. Includes one breakout tray. No 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 specific applications.
Refer to splice tray instruction to determine length required in tray.

• If you are installing cable with multiple buffer tubes that will be looped in the enclosure, use a midspan access kit (p/n OSE-A288-MSPN-KIT, purchased separately) to access the fiber 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.)
