3.2.3 Cable (FX3UC-4AD)
Use the following cables to connect with counterpart equipment. Terminate the cable end as shown below.
1. Cable
Applicable cable and tightening torque
2. Termination of cable end
To terminate the cable, treat the stranded/single-wire directly or use the rod terminal with insulation sleeve.
• To directly terminate end of stranded/single-wire cable:
- Terminate 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 rod terminal with insulation sleeve:
If the cable sheath 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 purchased small-sized screwdriver whose head is straight and is not widened
as shown in the right figure.
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).
