Assembling
The series 1331 provides a protective earth contact (
Receptacle and plug must be ordered so that in unmated condition the voltage always is on the side with the socket contacts.
Only the tools mentioned on page 4-7 may be used for assembling.

Connectors with solder contacts
Contacts are already installed in the inserts (only for contact layouts 303 and 405 contacts are delivered separately).and the cavities
are labelled consistently. Pass the cable through the backshell and the plastic ring and solder the wires with suitable tin and flux to
the contacts. It is preferable to start soldering in the center and go on circularly outwards. The solder duration should be as short
as possible to protect the inserts. Afterwards place the plastic ring on the insert and screw the backshell.
For connectors series 1332 (size 3 and 4 only) the plastic ring must be assembled in inverse direction (smallest outer diameter to
insert side).
Connectors with crimp contacts
Use the correct crimping tool and locator fort he current contact size. First shut the tool and reopen it to ensure the crimp jaws are
in correct position. Place the contact with wire side on top inside locator. Close the tool a bit to grip the contact. Insert the stripped
wires as deep as possible into the contact and push a bit against the contact. Make sure that all wires are inserted into the contact
and that they are not too much twisted. Shut the tool completely. Afterwards the contact can be removed from the tool. Visually
assure that the wires are viewable in the hole The contact may not be twisted or ripped.
The wires may not be pulled from the contact, teared away or deformed so that it becomes unusable before reaching the manda-
tory attraction. Broken wires which occur at lower forces and do not result from the crimp procedure are not seen as error. After the
cabling pass the contacts through the backshell and the plastic ring and use the mandatory tools to insert them into the insulator:

It is preferable to start inserting the contacts in the middle an go on circularly. After each contact insertion remove the tool without
canting. Damaged or twisted contacts may not be installed. Visually inspect the connector after all contacts are installed. On the
backside all pin or socket contacts must be on the same level inside or outside the insert.

Contact removal
Disassemble the parts in reverse order and move them over the wires.
Push the wire into the groove on the white side of the tool.

Slowly slide the tool along the wire into the contact chamber until it

reaches a stop position. This will disengage the contact retainer.
Push the wire against the tool and together pull them from the contact

chamber.
Remark
When using the metal tools the procedure ist he same.
Take the insert tool and insert the wire in the
colored side into the longitudinal groove.
Use your thumb to push the wire into the groove
and pull back the wire until the tool's top tou-
ches the contact shoulder.
Slowly push the tool together with the contact
into the right contact chamber until the contact
engages. Hold the tool upright during the instal-
lation process.
After the contact has engaged release the wire
and pull back the tool. Carefully pull on the wire
to make sure the contact is correctly engaged.
