With regard to the cable end treatment, use a stranded cable or solid cable as it is, or use a bar terminal with
insulating sleeve.
• When using a stranded cable or solid cable as it is
- Twist the end of a stranded cable so that wires do not get barbed.
- Do not plate the end of the cable.

• When using a bar terminal with insulating sleeve
Because it is difficult to insert a cable into an insulating sleeve
depending on the thickness of the cable sheath, select the proper cable
according to the outline drawing.
