5. Select crimping set (1, 2) 

 for crimp pliers (3) 

 . 

 Select crimping set(1, 2) 

 according to the crimp contact type and single-strand insulation used. See 

table. 

6. Insert crimping set (1, 2) 

 into crimp pliers (3) 

 .

7.

1. Screw positioner onto crimp pliers 

 (arrow).  

2. Fit positioner with quick-release fitting on crimp pliers 

 .  

 Positioners with screw fitting can be exchanged for positioners with quick-release fitting.

8. Insert crimp contact (1) all the way into crimp nest (2) and into positioner (3) of die sets (4, 5). 

 Select crimp nest (2) according to cable cross section. Crimp contact (1) must be vertical between the 

die sets (4, 5).

9. Close crimp pliers until crimp contact (2) is fixed in crimp nest (3). 

 Make sure that the crimp contact (2) is inserted correctly in the positioner (5). 

 Do not yet deform the crimp contact (2), as otherwise the line (1) cannot be inserted correctly into the 

crimp contact (2). 

10. Guide cable (1) with single-strand insulation (4) into inserted crimp contact (2) (arrow).

11. Squeeze crimp pliers 

 until stop is reached remove crimped connection.

 The crimp pliers 

 must be squeezed until stop is reached before they will open again.

12. Check crimped connection for deformation and ensure that the wires fill the crimp tab correctly (cross-

section of enclosed wires). 

 Correct crimped connection (A):  

The strands of the cable are evenly enclosed. The crimp tab is evenly shaped. 

 Incorrect crimped connections (B, C, D)  

The crimp shackle has the wrong cross-section. The crimp tab is not filled properly. Individual wire 
strands are outside the crimp shackle. The crimp tab is too full. The crimp claws touch the bottom of the 
crimped fitting. The crimp tab is too full. The crimp tab is deformed incorrectly and therefore damaged.

13. Check crimped connection to ensure that all wires are enclosed correctly. 

 Insulation and single-strand insulation must be positioned in the center and enclosed completely by the 

crimp tab and they must be able to take up tensile force. 

 Single-strand insulation must not be pinched otherwise galvanic corrosion can occur if the connection 

is penetrated by water. 

 Correct crimped connection (A):  

Wire strands are enclosed correctly by the shackle. Insulation and single-strand insulation are enclosed 
correctly by the large tab. All parts can withstand the required tensile force. 

 Incorrect crimped connections (B, C):  

The single-strand insulation is not enclosed by the shackle because it was inserted incorrectly during the 
crimping procedure. 

The crimped area of the single-strand insulation is damaged because the wrong die set or wrong single-
strand insulation was used.
