STEP 1 Prepare Cable
1. Check to be sure cable size fits within kit range as shown in the Termination Selection Chart, Page 1.
2. Train cable into position and cut to length required for installation. Allow sufficient neutral wire length for grounding connection.
3. Prepare cable using dimensions shown. Be sure to allow for depth of terminal lug. Provide additional exposed
conductor distance to account for growth during crimping of ALUMINUM lugs or connectors as follows:

4. Using 50% stretch, carefully wrap one (1) band of mastic around the cable jacket 1/4” (6mm) from jacket end as shown.
Position mastic carefully, it also serves as a marker for positioning the terminator. Cut mastic flush, do not overlap.
5. Bend neutral wires back over and press into sealing mastic, secure to cable jacket 4--6” (100--150mm) from cut edge using
vinyl tape or binding wire, see figure below.
6. Using 50% stretch apply a second mastic band over the neutral wires and previously applied mastic. Cut flush, do not overlap.
7. Wrap two half--lapped layers of vinyl tape around mastic seal, carefully maintaining the 1/4” (6mm) dimension, see below.

STEP 2 Install Lug or Connector
1. The termination assemblies are designed for use with Elastimold copper or aluminum lugs. If other lugs are used and will not
fit through the termination core, clean the insulation and slide termination on cable before installing lug. Do not remove core
at this time.
2. Position connector/lug and crimp according to directions. Do not crimp the last 1/4” to 3/8” of the connector. Remove excess
oxide inhibitor and sharp crimp flashings following crimping.

STEP 3 Clean Cable Insulation and Lug Barrel Using Standard Practice
1. Wipe the cable insulation with an approved solvent. Do not allow solvent to touch semi--con insulation shield.
2. If abrasive must be used:
a. Use on insulation only. Do not use abrasive on semi--con insulation shield.
b. Use only aluminum oxide abrasive; grit 120 or finer.
c. Be careful not to reduce the cable insulation diameter below that allowed by the kit.
STEP 4 Install Termination
1. IMPORTANT: A track resistant moisture seal must be made between termination insulator and lug/connector using gray
silicone rubber tape (contained in kit). Wrap a band of silicone tape around the base of the terminal lug.
a. If barrel diameter is equal to or greater than cable primary insulation, the tape band should not exceed 2 layers.
b. If barrel diameter is smaller than the cable primary insulation, use tape strip to form the tape band equal to
insulation diameter, see below.
2. Cover the edge of the semi--con insulation shield with a liberal coating of silicone grease. On this product the silicone
grease does not serve as a lubricant. It must be used to fill the step at the semi--con cut off.

3. On lowertermination with folddown skirt pullloose end of removable core through top of termination until the core isflush with
bottom of the termination.

4. Slide the termination body onto the cable align terminator with forward edge of mastic seal, see below. Carefully begin to
remove core while unwinding, counter--clockwise, starting with the loose end. Make sure the termination body, not the
core, is butted up to the leading edge of the masticseal, see below. Do not push or pull on the termination assembly
while removing the core material.

5. Apply a thin film of silicone lubricant to the skirt and mastic seal area. Do not lubricate skirt tabs. Carefully fold down skirt
over mastic seal.

6. With termination installed, complete the lug area moisture seal using the remaining gray silicone rubber tape.
Overlap the termination insulator by approximately 1” and extend the tape wrapping over a non--crimped region of the lug/
connector barrel with a half lap configuration, see above.
7. Twist concentric neutral wires together and connect to system ground.
High--K Step should overlap Cable Semi--Con
Not to Exceed 1.5”
8. Confirm that High--K step does not exceed 1.5”.
