3M 7685-S-8 Instructions for Wire Shielded Cable, Be Sure to Allow for Depth of Terminal LUG

Instructions for Wire Shielded Cable

7.0Prepare Cable

7.1Check to be sure cable size fits within kit size range as shown in Table 1.

7.2Prepare cable using dimensions shown in Figure 8 and 9. Refer to Table 3 for semi-con cutback dimension.

BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG.

NOTE: Provide additional exposed conductor distance to account for growth during crimping of ALUMINUM lugs or connectors as follows:

Aluminum Connector	2 - 350	400 - 650	750–1000
Growth Allowance	1/4” (6 mm)	1/2" (13 mm)	3/4" (19 mm)

NOTE: It is imperative to remove all remnants of the semi-con layer, even if the semi-con layer comes off as one layer. There should not be any remaining black areas, or particles, on the cable insulation layer.

	1.24" - 1.80"	750-1000	600-800	500-600	13.0"
	(31,5 - 45,7 mm)	(400 - 500 mm2)	(300 - 400 mm2)	(185 - 325 mm2)	(330,2 mm)
