3. Treatment of electric wire ends
Treat the ends of stranded wires and solid wires without coating or using bar terminals with insulating sleeve.
Tighten the terminals to a torque of 0.22 to 0.25 N
•
m.
Do not tighten terminal screws exceeding the specified torque. Failure to do so may cause equipment failures
or malfunctions.
• 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.

4. Tool
• For tightening the terminal, use a commercially available small screwdriver having a straight form that is
not widened toward the end as shown right.
Note :
If the diameter of screwdriver grip is too small, tightening torque will not
be able to be achieved. To achieve the appropriate tightening torque
shown in the table on the previous page, use the following screwdriver
or an appropriate replacement (grip diameter: approximately 25mm
(0.98")).
