PLUG 2211136 - Caterpillar

Applications
Tying/securing bundles of electrical wire or cables together in high temperature applications as would be done in manufacturing wire harnesses/assemblies, and in some cases, securing the harness bundle to a fixed mounting surface with a ladder clip, T-slot, chain link, or weld clip.
Securing cover jackets, sheathing and covers on hoses, exhaust, and electrical harnesses.
General use of cable straps for applications other than stated above may not apply to Figure 1 tensioning settings. Validation of a proper setting will need to be done beforehand or contact Design Control A526 for assistance.General Requirements
Cable straps are intended to restrain the product onto a mounting component or intended support surface.
Cable straps shall not be loosely tensioned. A loose stainless steel cable strap may allow wear of the restrained product, wear between the product and the adjacent mounting surface, or allow movement of the product through the strap.
Cable straps must not be overly tight to the product. An overly tight cable strap may damage the harness/hose covering or wiring insulation. An overly tight cable strap may damage electrical conductors and splices within the harness bundle.
Cable straps used for electrical applications shall be used to press the electrical wiring harness or cable to adjoining surface perpendicular to the axis of the harness bundle or cable. Before cable strap tensioning, the electrical wiring harness or cable shall be positioned in a manner that minimizes axial loading.Specific Requirements
Table 3 is a manufacturer's guide to determine the correct tool tension setting. Validation of the product to be secured shall be done.
Cable straps are to be hand tightened first as the part is routed/placed in correct position.
When tensioning cable straps, the tension tools will require up to (2) pulls of the lever. The first pull will bring the cable strap tight to the wiring harness or electrical cable; the second pull will tension the cable strap and cut the tail flush to the head of the cable strap.

Illustration 6 g03869552
Tensioning tools shall be serviced regularly to assure proper tensioning and avoid a sharp edge at the cutoff location, which could cause laceration to the skin. If a sharp edge is found when the cable tie is cut, the tension tool requires maintenance to have the blade changed.
Remove the screws from the nose piece. Carefully lift off the nose piece and remove and discard the old blade. Install the new blade with the bevel side facing towards the tool and the
