Inserting the crimped contacts into the insulator

1. Insert the crimped contact into one of the insulators in the configuration body.
2. Push and insert the shielding contact into the metallic part of the configuration body (shielded versions).
3. Check for proper contact placement.
   • The claws must hold the contact.
   • Female contact: It should be slightly recessed from the edge of the insulation.
   • Male contact: it should be slightly exceed from the edge of the insulation.
   • Pull on the cable to check that the contact is correctly clipped in the insert.

Cable gland tightening

• Tighten the cable gland to ensure seal-ing in the back of the cable by using the torque wrench and insert.

Recommended torque:

• Cable gland CG-M25: 15 N m

• Repeat this operation for each pole.

• Tighten pressure screw visual until pressure screw and sealing insert are at the same level.

Note

The cable glands are not suitable for dynamic application (lateral movements). The integrator must comply with the cable retention standards of the application:
Unless stated otherwise by the cable manufacturer, cables must be fixed in place at intervals no larger than the following values:

• 300 mm if the cables are placed horizontally along a surface
• 500 mm if the cables are placed vertically

Cable lug or busbar mounting

(ill. 25)

Connecting the cable lug or busbar to the contact LITE-X/CT-S10-IT-M8 consists of the following steps:

• Place cable lug or busbar on the contact
