4.2 Prepare cable as describe in the previous
armored cable prep section Wrap the sheath
with Scotch®All Weather Telephone Vinyl
Plastic Tape 88T or equivalent to protect fiber
from the sharp cable sheath edges. Do not wrap
the last inch (25 mm) of the cable sheath.
4.3 Prepare the closure base by locating the ground
studs inside the closure base. Loosen the upper
nut 3 to 4 turns on the ground stud using a 1/2
inch (13mm) nut driver. It is not necessary to
remove the small vinyl caps.
4.4 Place the forked end of the ground wire between
the pair of washers. Re-torque the ground stud
nut to 30 in-lbs.

678-8140-2401-0-B
4.5 Position and route grounds to minimize
interference with cables ports and splicing.
Cable end ground connections are made after
the cables are installed in the base.
Note: The installation and removal of the ECAM
27MM-D is the same for both the metallic and
the non-metallic versions. For demonstration
purposes, the metallic version will be used
throughout the instruction manual.
5.0 3M™Double Cable Assembly ECAM 27MM-D Removal
5.1 Using a 3/8 inch (10 mm) nut driver loosen the
clamp screws on the external cable assembly
module (ECAM). Pull clamps outward and
rotate as shown. Lightly re-tighten screw to
hold clamps in place.
5.2 Loosen the three screws and separate the top and
bottom halves of the 27-mm ECAM double cable
assembly using a 3/8 inch (10 mm) nut driver.
5.3 Loosen the three screws to remove the cable
clamp from the bottom half of the of the 27-mm
ECAM double cable assembly using a 3/8 inch
(10 mm) nut driver. Keep the longer center screw
located in the center position.

6.0 Cable Gauge Decal
Use the supplied cable gauge to determine the proper
cable clamp shells, washers and correct amount of
mastic needed to build a sealing collar.
6.1 Place the cable gauge decal on the cable as shown below. Be sure to place decal in-line with the cable.
Correct Incorrect
6.2 Read between the arrows on the decal to
determine the amount of mastic, clamp shells
and washer needed to properly assemble
the 3M™Double Cable Entry Port ECAM-
27MM-D. This information can be recorded in
the log at the bottom of this page.
Note: If the arrows on the decal point at the line
between two different sizes, use what is listed in
the box below the line. Also note that no clamp
shells are required if gauge indicates ‘NONE’ in
the shell column.
Note: If two differently-sized cables are used repeat this
procedure for the second cable and record this
information in the Cable 2 section of the log. LOG Mastic Cut

Note: To plug an unused port in the 27-mm Double ECAM assembly, use 14.0 inches (356 mm) of mastic rolled
into a cylinder.

7.0 Cable Clamp Shell Selection
7.1 Locate clamp shells on the clamp shell tree.
Note that each clamp shell is numbered.
Remove the required clamp shell sets from part
tree. Make two sets of clamp shells for each
cable.
7.2 If multiple shells are required for a specific
cable size, locate these and assemble into sets.
7.3 Note the orientation of pin and socket and
assemble as shown.
7.4 Assemble clamp shell(s) into the cable clamp.
Note the orientation of pin and socket and
assemble accordingly.

9
78-8140-2401-0-B
7.5 Assemble clamp shell(s) onto bottom half of
cable housing. Note the orientation of pin and
socket and assemble accordingly.
Note: Differently-sized cables may require differently-
sized clamps. Ensure that the correct clamp sets
matches the cable when assembling in bottom
housing and cable clamp.
8.0 Cable Seal Installation
8.1 First thoroughly clean the cable sheath using an
alcohol wipe. Make sure cable sheath is free of
any grease or dirt.
Note: Carefully follow health, safety and environmental
instructions as given on Material Safety Data
Sheet for the alcohol wipe.
Scuff the first 3" of each cable sheath using
the supplied sheath scuff. Ensure the cable is
completely scuffed around the perimeter of the
cable.
Hint: Scuffing is easier if you tear the sheath scuff in
narrow strips along the length of the strip.
Washer Selection
8.2 Locate and remove two washers on parts trees for each cable (four washers total). Note that washer
sizes are on washer as shown. Note that inches are on one side of the washer and millimeters are on the
other side.
Note: See chart in section 6.2 for required washer.

10 78-8140-2401-0-B
Mastic Collar Build
8.3 Mark cables approximately .25 inches (6 mm)
from the end of sheath. This is to locate the
mastic collar.
8.4 Washers can be split along notch for installation
over the cable.
8.5 Install two washers on each cable near sheath
end as shown.
8.6 Unroll mastic and measure out the required
amount. Repeat for second cable.
Note: See chart in section 6.2 for required mastic
length.
Note: Warm mastic before use if temperature is below
50°F (10°C).

11
78-8140-2401-0-B
8.7 Trim the corners from the mastic forming points at both ends.
8.8 Wrap the mastic starting 0.25 inches (6 mm)
from the sheath end. Wrap mastic evenly around
cable. DO NOT STRETCH MASTIC.
8.9 Release liner can be wrapped around mastic collar temporarily to keep mastic clean. Be sure to remove
the liner before installing the cable into 3M™Double Cable Entry Port ECAM-27MM-D housing.
Relocate washers next to collar. Repeat for second cable.

12 78-8140-2401-0-B
8.10 Peel the mastic rope from the liner and place into the groove in the 3M™Double Cable Entry Port
ECAM-27MM-D bottom half. Press mastic rope in place and route as shown. Make sure at least 0.25
inches (6 mm) of the mastic rope extends out both ends as shown.
8.11 Install the first cable into the external cable
assembly module (ECAM) housing bottom half.
Note the grooves in the housing for locating
washers.
Note: If differently-sized cables are used, ensure the
cable is placed into the correct cable clamp shell
set in bottom housing.
Note: On cables prepared for grounding, install the
cable into the bottom housing with cable sheath
tab facing up as shown.
8.12 Install the second cable into the housing. Note
that the washers are offset from the first set.
Note: Ensure washers are properly seated into their
corresponding grooves in bottom housing.

13
78-8140-2401-0-B
8.13 Install the cable clamp by positioning over the
cable set.
Note: If differently-sized cables are used,v ensure the
cable is placed into the correct cable clamp shell
set in bottom housing.
8.14 Start the center clamp screw (longer screw) and
lightly tighten. Evenly tighten the two outer
screws (shorter screws) along with the center
screw by alternating between. Torque all three
clamp screws to 30 in.-lbs.
8.15 Place top half of the 3M™Double Cable Entry Port ECAM-27MM-D. Align top and bottom housings
and squeeze the halves together evenly.
 CAUTION
Do not pinch fibers between halves.
8.16 Start all three of the screws. Then evenly tighten
the three clamp screws by alternating between
screws.

8.17 Finish tightening the two screws marked 'A' until the gaps between the halves are closed or nearly
closed. Then finish tightening the screw marked 'B'. Torque all three screws to 45 in.-lbs.
Note: Do not exceed 50 in.-lbs. of torque
8.18 Trim excess mastic using snips or knife.
Note: Do not cut flush or pull out rope mastic. Leave
1/8 inch (4mm) of the ends of the rope mastic
protruding.
8.19 Press mastic flat using a finger tip.
9.0 Cable Strength Member Installation; For all loose buffer tube and
dielectric central tube cables
9.1 Remove vinyl caps and cable strength member
(CSM) clamps from the CSM bracket. Position
CSM rod next to bracket and trim to fit as
shown.

15
78-8140-2401-0-B
9.2 Reinstall cable strength member (CSM) clamps
as shown and torque to 25 in.-lbs.
9.3 Install vinyl caps over the CSM clamps. Color
coded cable ties can be installed at this time
to attach caps, and can also be used to identify
feeder or distribution cables.
10.0 Cable Strength Member Installation; For armored loose tube cable
10.1 Please refer to 4460-D-SS instruction manual, 78-8135-4338-2 (3M™Scotchlok™Shield Bond

11.0 Cable Strength Member Installation For Armored Central Tube Cable
11.1 Please refer to 4460-D/FO-SS instruction manual, 78-8128-0289-6 (3M™Scotchlok™ Shield Bond
Connector Assembly 4460-D/FO and 4460-D/FO-SS) for shield bond installation.
12.0 3M™Double Cable Entry Port ECAM-27MM-D Installation
12.1 Lightly lubricate the oval gasket using the
supplied silicone lubricant before installing
the gasket into the groove in the base of the
3M™Fiber Dome.
Note: Follow health, safety and environmental
information. Refer to product label or Material
Safety Data sheet for silicone lubricant.
12.2 Feed cable through oval port
 CAUTION
Do not kink fiber. Handling small groups of
buffer tubes reduces chances of kinking.
