3. Treatment of electric wire ends
Treat the ends of stranded wires and solid wires without coating or using bar terminals with insulating sleeve.
• Treatment of stranded wires and solid wires without coating
- Twist the ends of stranded wires tightly so that loose wires will not
stick out.
- Do not solder-plate the electric wire ends.
• Treatment using bar terminal with insulating sleeve
It may be difficult to insert the electric wire into the insulating sleeve
depending on the thickness of the electric wire sheath. Select the
electric wire referring to the outline drawing.
