5 XF 95 series Removal and installation REPAIRING WIRING Insulation connection Different types of crimping are allowed: 1. Normal crimping; the two sides of the relief part fully engage the insulation. 2. Double crimping; two wires are clamped in one contact. 3. Overlap crimping; the two sides of the relief part engage one another slightly. 4. Double overlap crimping; two wires are clamped in one contact, the two sides of the relief part engaging one another slightly. A. If the insulation connection is correct, the wire is clamped in the relief part with the correct pressure and the insulation is not broken. 3 B.
If the contact pressure is too high the insulation could break, possibly causing a short circuit. This may for instance be caused by: - using the wrong crimping tool - using an improper hole in the crimping tool (too small) - a defect in the crimping tool delaying the interruption of the contact pressing. C. If the contact pressure is not sufficient the insulation may not be clamped and the wire may come loose. This will interrupt the electrical connection but may also result in a short circuit. This may for instance be caused by: - using the wrong crimping tool - using an improper hole in the crimping tool (too big) - interrupting the contact pressing prematurely. 200303 2-13
