-Do the insulation with shrinkable sleeves,
-For the connection of a gauge 4 aluminum wire to a gauge 6 copper wire, do the insulation with KYNAR sleeve ASNE0718.
(2)
Wire stripping
-Use the applicable tool.
-Strip the wire to the length "A" .
(3)
Crimping
-Use the applicable crimping tool related to the splice reference number.
-
Remove the locking pin and open the crimping head.
-
Remove the plastic blanking plug which closes the aluminum barrel.
-Be careful not to move the inhibitor.
-Put one end of the splice in the crimping die.
-
Close the head and install the locking pin.
-
Close the crimping tool handles sufficiently to hold the splice in position but do not crimp at this stage.
-Engage the two insulation sleeves (70 mm (2.7559 in.) and 80 mm (3.1496 in.)) on the wire (In case of connection of an aluminum wire to a copper wire).
-Remove and retain the opposite blanking plug. Make sure that the wire is in the correct position.

-Put the stripped end of the wire in the splice barrel.
-Tightly hold the wire in the barrel
-Crimp the splice. To do this, fully close the tool handles until the safety ratchet releases.
-Install the blanking plug.
-Remove the locking pin.
-Open the crimping head and remove the splice from the crimping machine.
-Remove the inhibitor, if necessary.
-
Do the same procedure from step 2 for the other end of the splice.
-
Do a check of the crimping. Crimping is correct when:
-you can see the figure related to the wire gauge on the splice.
-this figure is in correct position.
(4) Sleeve shrinking
-Put the shorter sleeve (70 mm (2.7559 in.)) in the correct position on the splice. You must see the sleeve on a length of 0.5 mm (0.0196 in.) minimum on each side of the wire.
-Shrink the sleeve with the applicable tool.
-Wait until the sleeve is cold.
-Put the longer sleeve (80 mm (3.1496 in.)) in the correct position on the splice
-Shrink the sleeve with the applicable tool.
-Make sure that the sleeves are in the correct condition.

A. P/N Identification
NSA936813 RH0604 | | | | | R = Splice Code | | | H = Type | |------------- Reference N. | 06 = Copper wire gauge | | 02 = Aluminum wire gauge | ----------------------- Standard P/N
B. P/N Characteristics
-This type of splice is used to connect gauge 4 aluminum wires or gauge 4 aluminum wire with gauge 6 copper wire. Example: Aluminum wires: E0438 YV 4, NSA935308 YU 4, NSA935290 YA 4. Copper wires: E0262DK 6 , NSA935131DG 6.
(1) Temperature Minimum operating temperature is -55 deg.C (-67.00 deg.F). Maximum operating temperature is 150 deg.C (302.00 deg.F).
C. Connection Procedure
(Ref. Fig. 011)
(1)
Insulation
-Do the insulation with 2 shrinkable sleeves E0718 . Install these sleeves on the wires before stripping. Shrinking is made after crimping.
(2)
Wire stripping
-Strip the wire to the length "A"of 15 mm (0.5905 in.) from the wire end.
-Make a mark at 25 mm (0.9842 in.) from the wire end.
(3) Crimping R (Ref. Fig. 011)
-Use the applicable crimping tool , head and die.
-Make sure that the insulation sleeves are engaged on the wires.
-Put one end of the splice in the crimping tool die with the cross marking aligned with the crimping die.
-Lightly push the tool pedal to hold the splice in position but do not crimp at this stage.
-Put the stripped wire end in the splice barrel. The 25 mm (0.9842 in.) mark must be at the splice end.
-Tightly hold the wire in the barrel.

-Crimp the splice. To do this push the pedal until the ratchet releases.
-Remove the splice from the crimping head.
-Crimp the other end of the splice as follows:
-Turn the crimping head by 180 deg.
-Put the other end of the splice in the crimping head. Turn the splice by 180 deg. and do the second crimping in a direction opposite that of the first crimping.
