4.3: Adjust Crimping Tool

If needed, following below steps to adjust the pressure force to optimize crimping.

I. Loosen the screw (A) with a screwdriver.

II. Turn the dial counter (B) clockwise (+) to increase the crimping force. This also reduces the jaw spread.

III. Turn the dial clockwise (-) to reduce the strength of the crimping force. This also increases the jaw spread. Do exceed 180N.

IV. After changing the setting, make sure the screw is adequately tightened.

4.4: Crimping quality verification

Great variations exist in the diameter, quantity and cross section of strands between PV cables made by different

manufactures, so the above dimensions are only for reference. In order to get quality crimping, please verify the pull

force and crimping cross section.

Pull force between the contact and cable should meet to UL486a-486b, refer to the table in section 4.2

The cross section inspection standard:

• The crimp shall have all cable strands compressed into a hexagonal shape with minimal voids.

• No cracks/fractures in crimp material or wire stranding

• Ensure symmetrical and uniform distribution of strands

• All strands are captured within crimp

• Crimp wings are fully closed at surface. Crimping wings are curled evenly and uniform

• The burr on the base of the crimp must not exceed 0.1mm, and will not scratch the sealing component in the next

assembly process

• Crimping cross section criteria can be found in USCAR21as below
