Appendix D
Cable Replacement Procedure
Page D-5
1.
Slide plastic case and then the grommet onto new cable.
2.
Slit the jacket lengthwise 1 3/8 in (35mm). With ScTP, cut the
foil shield back to the jacket, leaving the drain wire intact. Pull
the jacket away and then cut it off close to the bundle.
NOTE:
Observe carefully the direction of the wire’s twist.
Proper installation requires this same twist direction
right up to the screw terminals. When viewed from
the end most wire twists clockwise as it approaches
the wire’s end.
3.
Arrange the cable and wire pairs as shown in Figure D-2. Do
not untwist the pairs any more than required to strip the wire
ends.
4.
Cut the two inner wire pairs (orange and blue for EIA/TIA
T568A) to 1 1/8 in (28mm) from the jacket.
5.
If using ScTP, cut the bare drain wire to 1 inch (25 mm).
6.
Remove insulation 1/4 in (6 mm) from the end of each wire and
twist to capture all strands. Optionally, tin the ends to capture
all strands.
7.
Re-twist each wire pair in their original direction. Use two or
three full twists for the two outer pairs and one or two twists for
the two inner pairs.
