Screwdriver with fine tip e.g. 3 × 75 mm

Goal: crimping pliers emergency opening.

Action step:
• Turn the screw with the screwdriver
(clockwise/counterclockwise).

Result:
• The locking mechanism loosens.

Note:
Once the crimping pliers have been opened using the
emergency opening, the metal crimp in process needs to be
discarded.

Exchanging the crimping die

Removing the crimping die

(ill. 5)
• Close the crimping pliers and hold it
closed.
• Unlock the locator (if still mounted);
• pull it upwards out of the crimping
pliers.

(ill. 6)
• Completely unscrew screw S (long)
and S1 (short) completely using an
Allen key 2.5 mm (not included in
scope of delivery).
• Open the crimping pliers.

(ill. 7)
• Remove the upper crimping die.

(ill. 8)
• Remove the lower crimping die.

Fitting the crimping die

(ill. 9)
The crimping dies can be inserted only
when the handles are open. Insert the
dies separately. The laser identification
of the dies needs to face towards the
operator as well as the crimping pliers
identification.

Note:
When inserting the dies make sure
that the anvil (lower die) is inserted
first, only then insert the punch.

• Close the crimping pliers.
• Place the screws in the correct position.
Do not damage the screw
heads.

(ill. 10)
• Screw in screw S (long) and S1 (short)
completely.

Note:
The pictures describe the locator for MC4-Evo 2 crimps. The
assembly of the locator for MC4 is comparable.

(ill. 11)
1. Affix locator onto the guide pin.
2. Rotate the locator (held magnetically).
3. Lock the locator.

Crimping

(ill. 12)
• Open clamp (K) and hold tight.
• Insert the contact in the appropriate
cross-section range.
• Turn the crimping flaps (C) upwards.
• Release clamp (K).
• The contact is locked.

(ill. 13)
• Verify if the crimping flaps are still
correctly aligned.

• Press the crimping pliers gently
together until the crimping flaps are
properly located within the crimping
die.

(ill. 14)
• Insert the stripped cable end until
the cable strands come up against
the clamp.
• Completely close the crimping pliers.

Note:
Observe the stripping length of the
PV cable supplier.
Do not damage strands when stripping
the cable!

(ill. 15)
After crimping,
• move the locator to default position
• remove contact
(see arrow in ill. 15 for interaction to
achieve default position of locator).

Note:
The crimp terminals shall not be released
from the crimping pliers under
force. They should come out easily.

Verify the crimped assembly

(ill. 16)
Visually check the crimp according to criteria listed in
IEC 60352-2.

Confirm that:
• All of the strands have been captured in the crimp sleeve
• The crimp sleeve is not deformed or missing any portion of the
crimp flaps
• That the crimp is symmetrical in shape
• A “brush” of conductor strands are visible on the contact side
of crimp.

• Verify crimp height. Typical values for the crimp height for
Stäubli PV cable Flex-Sol-Evo TX and Flex-Sol-Evo DX are
listed below:
