C. Procedure
(1) Installation
The installation procedure for the lacing tape is related to the
dimension code used.
R (a) Standard installation
R
R _1 Lacing tapes NSA8420-1, -2 or -7
(Ref. Fig. 004)
- Fold the tape in two and make a loop.
R - Wind tape around bundle.
- Turn the ends of the tape into the loop.
- Tighten the knot.
- Add a single knot.
- Cut the tape ends to approximately 6 mm (0.2362 in.) with
scissors.
R - Put a drop of CAF 4 (Material No. 08-004) on the knot (in
R high temperature areas only).
R _2 Lacing tapes NSA8420-3, -4 or -8
R (Ref. Fig. 005)
R - Wind the tape two times around the bundle.
R - Tighten the knot.
R - Add a single knot to the first knot.
R - Cut the tape ends to approximately 6 mm (0.2362 in.) with a
R heat stripper (TMC No. PB19 or PB19M), a hot soldering iron
R or scissors.
R
R _3 Lacing tapes NSA8420-3, -4, -7 or -8
(Ref. Fig. 006)
R - Wind the tape two times around the bundle.
R - Add a single knot on the two loops.
- Tighten the knot.
- Add a single knot.
- Cut the tape ends to approximately 6 mm (0.2362 in.) with a
heat stripper (TMC No. PB19 or PB19M), a hot soldering iron
or scissors.
R - Put a drop of CAF 4 (Material No. 08-004) on the knot (in
R high temperature areas only).

R (b) special cases
_1 Wiring of feeder cables to terminal blocks.
(Ref. Fig. 007)
To prevent cable friction when feeders are cross-connected to
terminal blocks, a hanging type knot must be made between two
crossed cables with lacing tape NSA8420-1, -2 or -7.
R _2 Separation of "G" routes in high temperature areas
R (Ref. Fig. 007)
R _3 Wiring of optical fiber cable
R Optical bundles are tied by lacing tape NSA8420 or cable ties
R NSA935401-3 after protection by a bushing NSA5539 installed on
each optical cable at each attachment point.
R _4 For overbraiding:
R _a Whipping knot with lacing tape NSA8420-7.
R (Ref. Fig. 008)
R _b Separation knot with lacing tape NSA8420-7.
R (Ref. Fig. 009, 010)
(2) Removal
R Cut the lacing tape with scissors held parallel to the cables so that
R you do not cut the cables.
