-ABS0677
-ABS0774
-E0254
-E0420
-E0659
-E0664
-E0675
Two-Bundle fasteners (double V) with the codes that follow :
-ABS0354
-E0255
-E0660
Multiple-bundle fasteners for the :
-ABS0355
-E0661
-E0663
-
NSA935504
This group of cable support is used in pressurized areas only.

B. Procedure
(1) Use the applicable cable support, depending on the instruction data
or the bundle diameter. R (Ref. Fig. 005)
____
NOTE : When open supports are used, example NSA935504 and equivalent, the diameter of the bundles must not be more than the width of the vee in the support.
(2) Install the cable support on the structure.
R (Ref. Fig. 006) There are three methods :
(a) Clip-type attachment:
For ABS0354 or ABS0774:
A plastic hammer can be used.
____
NOTE : You must use an anti-corrosion paste (Mat. No. 05-7070) to install this type of cable support if paint coating is removed.
(b)
Rivet-type attachment: For E0659, E0664 or NSA935504: The head of the rivet is supported on the cable support side.
(c)
Screw-type attachment:
_For ABS0677, E0254, E0255, E0660, E0675 or NSA935504:
1 Add a screw type NSA1096 and a clipnut:
_For ABS0355, E0420, E0661 or E0663:2 -Assemble the components to form the cable support.
-Make sure that the support is correctly turned. R (Ref. Fig. 007)
-Tighten the cable support to between 0.25 m.daN (22.1238 lbf.in) and 0.35 m.daN (30.9734 lbf.in).
-After installation and tightening, make sure that the blade is supported correctly and that the assembly is stable.

(3) Install the bundle on the cable support. R (Ref. Fig. 008)
-If necessary, protect the bundle at location of support.
____
NOTE : You must make sure that a coaxial cable (e.g. E0406WD) has a protection of an NSA935510 bobbin at the fastener point.
____
NOTE : On bundles of a diameter more than or equal to 35 mm (1.3779 in.), use silicone tape NSA935403 or adhesive fiber glass tape ASNA3565 or red tape ASNA5107 to prevent damage to the periphery of the bundle at location of support (approximately 2 turns).
