1.0 Kit Contents 3 High–K, Tracking Resistant, Silicone Rubber Terminations 3 Pre-formed Ground Braids 3 Constant Force Springs 3 3M™ EMI Copper Foil Shielding Tape 1181 Strips, 1/2" x 10" 6 Strips Scotch® Mastic Strip 2230 (black with white release liners, bagged) 1 3M™ Cable Cleaning Preparation Kit CC-2 1 Instruction Sheet Note: Do not use knives to open plastic bags. Kit Selection Table NOTE: Final Determination Factor is cable insulation diameter.
2.0 Instructions for Tape Shielded Cable Prepare Cable 2.1 Check to be sure cable size fits within kit range as shown in Table 1. 2.2 Prepare cable using dimensions shown in Figure 1. BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG. If necessary to prevent tape shield from unrolling, hold down edge with a single wrap of 3M™ EMI Copper Foil Shielding Tape 1181.
3.2 Position pre-formed ground braid with short tail over tape shield directly adjacent to cable jacket cut edge. PLEASE NOTE: The ground braid needs to make full contact with the metallic tape shield. Position long tail of ground braid, extending over cable jacket with solder block over mastic strip (Figure 3). Secure ground braid to cable jacket 4-1/2" (114 mm) from cable semi-con edge using vinyl tape (Figure 3).
3.5 Wrap two highly stretched half-lapped layers of electrical grade vinyl tape around Scotch® Mastic Strip 2230, constant force spring and exposed tape shield (Figure 5). NOTE: Take care not to cover exposed semi-con insulation shield. A minimum of 1" (25 mm) must be exposed.
.0 Install Termination 6.1 Slide the termination body onto the cable and remove core. Make sure the termination body (not the core) is butted up to the edge of the vinyl tape marker previously applied (Figure 7). Pull the core while unwinding, counterclockwise, starting with the loose end (Figure 7). Be sure to alternate the pulling and unwinding actions (pullunwind-pull-unwind-etc.) to help prevent the core material from binding up as the core is being removed.
Instructions for Wire Shielded Cable 7.0 Prepare Cable 7.1 Check to be sure cable size fits within kit range as shown in Table 1. 7.2 Prepare cable using dimensions shown in Figure 8 and Figure 9. BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG.
.0 Install Ground Braid 8.1 Select a Scotch® Mastic Strip 2230 from kit and remove white release liners. Using light tension apply a SINGLE WRAP of mastic around the cable jacket 1/4" (6 mm) from cut edge (Figure 10). Cut off excess. 1/4" (6 mm) Semi-Con 1st Scotch Mastic Strip 2230 ® Cable Jacket Figure 10 8.2 Position pre-formed ground braid with short tail over wire shield directly adjacent to cable jacket cut edge.
8.3 Wrap ground braid around cable shield wires one complete wrap, trim excess to prevent overlap and secure in place with constant force spring. Wrap spring in same direction as ground braid (Figure 12). Cinch (tighten) the spring after wrapping the final winding. 8.4 Select second Scotch® Mastic Strip 2230 from kit and remove white release liners. Apply a second SINGLE WRAP of mastic over solder block on ground braid and previously applied mastic (Figure 12). Cut off excess.
9.0 Install Lug or Connector Important Packaging Notice In order to make sure that you receive an undamaged termination, this 3M™ Cold Shrink QT-III Termination is packed with a RED SHIPPING CORE inside of the white core. Please remove the red shipping core BEFORE you install the termination. This shipping core can be recycled with other polypropylene waste 9.1 Check to insure 3M™ Cold Shrink QT-III Silicone Rubber Termination fits over the selected lug or connector.

NOTE: To ease jacket removal, install constant force spring as shown in Figure 18 and ring-cut 80% through jacket.
.0 Install Ground Braid 13.1 Select a Scotch® Mastic Strip 2230 from kit and remove white release liners. Using light tension apply a SINGLE WRAP of mastic around the cable semi-conductive jacket 1/4" (6 mm) from shield wires (Figure 19). Cut off excess. 1/4" (6 mm) Semi-Con Shield Wires 1st Scotch® Mastic Strip 2230 Figure 19 13.2 Position pre-formed ground braid with short tail directly over cut edge of folded back shield wires.

NOTE: Take care not to cover exposed semi-con insulation shield. A minimum of 1" (25 mm) must be exposed.
NOTE: Refer to pages 17-19 for 3M ™ connector and lug crimping information. NOTE: For Aluminum Conductors - Thoroughly wire brush conductor strands to remove aluminum oxide layer. Insert conductor into lug or connector and then remove conductor. This will transfer some of the antioxidant compound onto the conductor. Wire brush the anti-oxidant paste into the strands. Immediately insert conductor into lug or connector barrel as far as it will go.
