3M™2178-L/S Series Fiber Optic Splice Case Description

1.0 General

1.1 The 3M

™

2178-L/S Series Fiber Optic Splice Cases are closures that can be used in buried, underground,

aerial, and pedestal applications. These closures are suitable for short term pressurization during flash

testing. Please refer to your company's approved applications. Each splice case has two cable

entrance ports on each end. Port plugs allow the cases to be used for butt or inline splices. The rigid

non-encapsulated case provides moisture protection. A gasket is used to seal the closure and provide

easy reentry.

1.2 The 3M™2181-LS Cable Addition Kit expands the case to provide more cable entries. It can be used on

the 3M™2178-S, 3M™2178-LS or 3M™2178-LL Splice Cases. The cable addition kit can also be added

to increase splice capacity.

3M™2178-S, 2178-LS, 2178-LL Fiber Optic Splice Case Instructions

Note: If wall mount bracket is required for the 2178-S

Splice Case or the 2178-LS Splice Case, use the

3M™2198 Mounting Bracket Kit. Attach

brackets to base (as shown) prior to cable

preparation.

Torque bolts to 25 in-lbs ±5 in-lbs

(2.8 N•m ±0.6 N•m).

3.6 Additional Materials Required:

• Cable Cleaner

• #6AWG Ground Wire or equivalent

• Splice Tray / Organizer

•3M

™

Scotchlok™4460 D/FO Shield

Bond Connector, if using shielded

cables

• Cable Splicer Knife

• Tape Measure

• Wire Cutter for Steel Strength Members

• Electrician's Scissors

• Screwdriver

3.7 Tools Required:

• 3/8" (10 mm) Hex Driver

• 1/2" (13 mm) Hex Driver

• 7/16" (12 mm) Hex Driver

• Side Cutting Pliers

• Needle Nose Pliers

• Cable Stripper

4.0 Cable Preparation

Note: When removing cable sheathing, do not cut, kink, or damage underlying layers. If damage occurs,

cut back sheath to adequately inspect and repair.

4.1 Remove 96" (244 cm) of outer cable sheath (and shield or armor, if present). Remove successive sheath

layers and wrapping to expose primary tubes protecting fibers. Stagger layers as recommended by cable

manufacturer or per standard practice.

4.2 Remove all cable grease. Clean all primary tubes and dielectric strands with approved cleaner. Cover all

sharp edges with vinyl tape.

Note: Carefully follow health, safety and environmental instructions as given on Material Safety Data

Sheet or container label for cable cleaner solvent being used.

4.3 Trim any solid filler tubes and discard.

Note: Do not trim strength members at this time.

4.4 Scuff 5" (127 mm) of each cable end using supplied sheath scuff.

Note: Do not use a carding brush to scuff sheaths.

Note: If wall mount bracket is required for the

3M™2178-LL Splice Case, use the 3M™2199

Mounting Bracket Kit. Attach brackets to base

(as shown) prior to cable preparation.

Torque bolts to 25 in-lbs ±5

in-lbs (2.8 N•m ±0.6 N•m).

Note: Proper sealing of the 3M™2178-L/S Series Fiber Optic Splice Case depends on strict adherence to

these instructions and the use of specified materials. Deviations can cause leakage or case damage.

Maintain clean sealing surfaces to ensure proper sealing. DO NOT USE any release agents or other

unspecified materials. These types of materials may lead to loss of sealing effectiveness.

Note: Installation procedures are the same for all combinations of the 2178-S, 2178-LS, and 2178-LL Splice

Cases.

5.0 Strength Member Termination

5.1 Slide two sealing washers down each cable. Use sealing washers with smallest inside diameter which

will slide on cable.

Note: If necessary, sealing washers can be split and placed on the cable.

5.2 Locate cables in appropriate entrance ports, as shown.

5.3 Strength Member Termination for Non-Shielded Cable

a. Cut strength member 1.75" (44.5 mm) from cable

sheath end.

1.75" (44.5 mm)

b. Install strength members into 3M™ 2172 Strength Member Clamp by loosening screw and placing

strength member under screw assembly. Insure strength member is flush with end of clamp prior to

tightening the screw. Install rubber boot onto clamp.

Note: To insure proper fit, remove coating on strength member.

6.2 The gasket is factory installed in the 3M

™

2178-L/S

Series Fiber Optic Splice Case. For replacement of

the gasket, place the gasket into the sealing channel

with the gasket ports opening from the top. Match

"AIR VALVE END" note on gasket with air valve

end on closure.

6.1 Inspect closure base and ensure the surface is clean

and free from any debris.

6.0 Gasket Installation

Note: Gasket cannot be used as a replacement for the

original mastic sealant in a reentry.

5.4 Bonding and grounding for shielded cable.

Note: Use care when installing shield bond connectors so underlying layers of cable are not damaged.

a. Install 3M™Scotchlok™4460-D/FO Shield Bond Connector following instructions provided with

connector.

Note: To insure proper fit, remove coating on central strength

member.

b. If separate external grounding is required, bond

"Feeder Cable" and "Distribution Cable"

directly to separate ground studs.

Note: Torque ground stud nut to 35 in-lbs ±5 in-lbs

(4 N•m ±0.6 N•m).

c. If separate external grounding is not required,

bond across splice to either ground stud.

stabilizing pad

6.3 Use the 1.5" (38 mm) rubber tape included with the gasket

to build the cable seals. Check the placement of the tape

by positioning the strength member clamp where it will be

anchored to the cable tie down bracket.

Wrap the supplied rubber tape between sealing washers

2" (51 mm) from cable sheath end.

The tape should be wrapped to 1" (25 mm) outside

diameter. Use the Tape Collar Gauge to determine tape

wrap. Tape wrap should not be smaller than the left side

of the gauge, and not larger than the right side of the

gauge.

Note: Stretch tape slightly to ensure better fit between

washers.

Note: If using 1" (25 mm) cables, the supplied 1.5" (38

mm) rubber tape is not required.

6.4 If using sealing plug(s), apply the supplied 1.5" (38 mm)

rubber tape to the plug(s).

Wrap tape to 1" (25 mm)

outside diameter, approximately 2 1/2 wraps. Tape collar

gauge can be used to determine tape wrap.

6.5 Apply the supplied silicone grease to the inside and

outside of the port area on the gasket. Apply the grease

to the gasket area between the ports, and to the top of the

gasket along the sides of the closure.

Note: Carefully follow health, safety and environmental

instructions as given on Material Safety Data Sheet

for the silicone grease.
