2. Using a small knife, cut off the wire retainers

(strain relief) of the connector. This will provide a

clear view for inspecting the connector for a

properly terminated wire in the contact. See

Figure 3.

Wire retainers are removed in a connector for

testing only. DO NOT use such connectors for

productionapplication.

3. Make a test termination according to Steps 1

through 6 of Section 5, TERMINATING

PROCEDURE.

4. Push the connector out of the right side of the

head.

5. Check that the wire insertion depth is within the

dimension given in Figure 3.

To obtainthe wire insertiondepth, measure from

the front of the contact beam to the center of the

wire as showninFigure3-or- measure from

the front of the contact beam to the back of the

wire and subtract the wire diameter divided by 2.

If it is not, proceed as follows:

For the manual handle assembly, refer to

Section 4, WIRE INSERTION DEPTH

ADJUSTMENT.

For the pneumatic handle assembly, if the wire is

inserted too deeply (more than the required wire

insertion depth), refer to Section 4, WIRE

INSERTION DEPTH ADJUSTMENT. If the wire is

not inserted deeply enough (less than the required

wire insertion depth), increase the air pressure by

69 kPa [10 psi]. Repeat the termination procedure

and check the insertion depth. Continue in this

manner until either the proper insertion depth is

obtained or the air pressure is set to 483 kPa

[70 psi]. If the proper insertion depth is NOT

reached at 483 kPa [70 psi], return the air pressure

to 276 kPa [40 psi], and refer to Section 4.

6. Inspect the termination according to

Paragraph 3.2.

Refer to 114-1019 for detailed explanation of the

termination inspection requirements.

1 — The required wire insertion depth is within the

dimension given in Figure 3 (refer to Step 5 of

Paragraph 3.1 for measurement).

2 — The end of the wire extends past the contact

beam by at least 1.52 mm [.060 in.].
