Each die assembly, when installed in the crimping head, crimps AMPOWER Quick-Disconnect Terminals onto

standard wire sizes as listed in Table 3.

These instructions provide specific information regarding the die assemblies and applicable terminals. For

information regarding die insertion/removal and general operation, refer to the appropriate series 408

instruction sheet or series 409 customer manual listed in Table 2.

2. DESCRIPTION

Each die assembly features a stationary die, a moving die, and a locator assembly (see Figure 1). Both the

stationary and moving die have a shank (with a flat), which aligns and secures each die in the crimping head.

The locator assembly helps position the terminal in the stationary die.

3. INSTALLING AND REMOVING THE DIES

For installation and removal procedures, refer to instruction sheet 408-2458.

4. CRIMPING

DANGER

Moving parts can crush and cut. To avoid injury while operating the power unit, exercise caution when holding terminals or

wires near the crimping area.

1. Select a wire of the correct size and insulation diameter for the terminal (see Table 3). Verify that the

same wire size is stamped on the terminal and the dies.

2. Strip the wire to the length listed in Table 3. Do not nick or cut wire strands. See Figure 3.

3. Insert the terminal into the stationary die. Orient it so that the large, flat surface of the terminal is

parallel to, and rests against, the angular surface of the locator (Figure 4).

4. While holding the terminal in position, activate the power unit so that the moving die advances just

enough to hold the terminal in place. Do not deform the terminal wire barrel.

5. Insert the stripped wire all the way into the terminal wire barrel.

6. While holding the wire in place, activate the power unit through a complete cycle.

7. Allow the dies to open fully.

8. Remove the crimped terminal.

5. INSPECTING THE CRIMP

Inspect crimped terminals by comparing to the ones shown in Figure 5 and Figure 6. Use only the terminals

that display the features of an acceptable crimp (Figure 5).

Embossed wire size matches size stamped on terminal and CMA of wire.

Figure 6 shows problems that mean a crimp should be rejected. Most of these are the caused by a terminal

that is not properly aligned with the dies. Avoid unacceptable crimps by carefully following the procedures in

section 4 and performing regular tool maintenance (section 6).

As shown in Figure 6, the large slot in the terminal must meet the following requirements:

The height of the slot must be 6.35 to 6.48 mm [.250 to .255 in.].

At least 2.00 mm [.079 in.] of slot flat must exist.

If the slot is spread open too far, you can correct this by squeezing it in a vise.

Figure 6: Reasons to reject a crimp

Excessive flash. Damaged dies or wrong wire, terminal, or tooling combination was used.

Embossed wire size does not match size stamped on terminal or CMA of wire.

Strands are nicked or missing.

Large slot is deformed (spread open).

Incorrect crimp orientation.

Crimped too far off center, causing large slot to spread open.

Wire was not inserted far enough into terminal. Wire insulation did not enter insulation barrel.

6. MAINTENANCE AND INSPECTION

The dies are inspected before being shipped. Inspect them immediately when they arrive at your facility to

determine whether any damage occurred during shipment.

6.1. Daily maintenance

Make each operator of the power unit aware of, and responsible for, the following daily maintenance

requirements:

Remove dust, moisture, and other contaminants with a clean, soft brush or soft, lint-free cloth. Do not

use objects that could damage the dies.

Protect all surfaces with a thin coat of any good SAE 20 motor oil. Do not oil excessively.

When the dies are not in use, store them in a clean, dry area.

6.2. Lubrication

To protect dies from rust when storing, lubricate all surfaces with SAE 20 motor oil as indicated in Table 5.

Table 5: Lubrication schedule

When to lubricate

In daily production

Daily

Daily (occasional)

Weekly

Monthly

Before using the dies, wipe off excess oil, particularly from the crimping area. Oil transferred from the crimping

area onto terminations can affect the electrical characteristics of the termination.

6.3. Periodic inspection

Regular inspections should be performed by quality control personnel. A record of scheduled inspections

should remain with the dies or be supplied to personnel responsible for the dies. Recommendations call for at

least one inspection per month. Base your inspection frequency on the amount of use, ambient working

conditions, operator training and skill, and established company standards. Perform the inspection as follows:

1. Remove accumulated dirt, grease, and foreign matter by immersing the dies in a suitable commercial

degreaser that does not affect paint or plastic material.

2. Inspect the crimp area for flattened, chipped, cracked, worn, or broken areas.

3. If damage or abnormal wear is evident, replace the dies. Refer to section 7, REPLACEMENT AND

REPAIR.

6.4. Gaging the crimping die closure

This procedure requires the use of a plug gage (Figure 7) conforming to the dimensions listed in Table 6. TE

Connectivity does not manufacture or market these gages. For information regarding the use of a plug gage,

refer to instruction sheet 408-7424.

To gage the die closure, complete the following steps.

1. Remove the dies from the crimping head.

2. Remove traces of oil or dirt from the crimping chambers and plug gage.

3. Position the dies at the gaging height shown in Figure 8.

Figure 8: Gaging height

4. Align the GO element with the wire barrel crimping chamber. Gently push the element straight into the

crimping chamber. The GO element must pass completely through the crimping chamber.

5. Gage the wire barrel crimping chamber with the NO-GO element in the same manner as step 4. The

NO-GO element can start entry, but must not pass completely through the crimping chamber.

If the dies conform to the gage inspection, the crimping chamber is considered dimensionally correct.

If correct, lubricate the dies with a thin coat of any good SAE 20 motor oil and return them to service.

If not correct, return the dies to TE for further evaluation and repair. Refer to section 7,

REPLACEMENT AND REPAIR.
