3.2 Applicable Cables and Terminal Tightening Torque
Use the following cables to connect with the counterpart equipment. Terminate the cable end as shown below.
1. Cables
Applicable cable and tightening torque
2. Termination of cable end
To terminate the cable, treat the stranded/single wire directly or use a rod terminal with insulation sleeve.
• To directly terminate the end of a stranded/single-wire cable:
- Twist the end of the stranded cable so that the "barbed wires"
cannot protrude.
- Do not solder-plate the end of the cable.
• To terminate cable end using a rod terminal with insulation sleeve:
If the cable cover is too thick, it may be difficult to insert the cable into
the insulation sleeve. For this reason, select an appropriate cable while
referring to the external view.
3. Tool
• To tighten terminals, use a small-sized screwdriver whose head is straight and is not widened as shown in
the figure to the right.
Note:
If the diameter of screwdriver grip is too small, tightening torque will not
be able to be achieved. Use the following recommended screwdriver or
an appropriate replacement (grip diameter: approximately 25mm).

• To connect a stranded cable, peel the cover off the cable
and then twist the core before connection.
• To connect a single-wire cable, just strip the cover off the
cable before connection.
