Half-Tap Splicing

Basic Technique for Half-Tap Splicing 3M

™

3M710 25-Pair Modules

23. Prepare the sheath opening,
allowing additional slack to the
“through” cable pairs as follows:
Less than 900 pair cables = 

127mm (5mm)

900 - 1800 pair = 127 - 178 mm

(5-7”)

1800 and above = 178 - 230mm 

(7-9”)

24. Fit an index strip to the
Unipresser. Select a “trough”
group to be half-tapped and
dress the pairs into the index
strip. The cable side to be
removed must exit the index
strip towards the operator and
“T” bar. 

The conductors must

lay through the index strip
straight and must not be
pulled tight.

25. Check for wire dressing
errors with an error tester. (fig. 4
#2) DO NOT CUT AND SEAT
THE CONDUCTORS.

26. With the cathedral windows
facing the operator/front, posi-
tion a straight/half-tap module
body on top of the index strip
and engage the two with finger
pressure. Ensure the “trough”
cable pairs exit the module neat-
ly and do not restrict movement
of the “T” bar.

27. Operate the “T” bar handle to
seat and lock th body to the
index strip. At the same time, the
module contacts connect across
the “trough” cable conductors.

28. Dress the new cable pairs
into the module;e body and

repeat steps 16 through 22.
