Optical Wiring Section 3-3
3-3-6 Connecting Backup Power Supply Cables
Attach crimp terminals to the power supply cable when connecting the backup
power supply to the Controller Link Unit.
Crimp Terminals
Use M3 crimp terminals, as illustrated below.
H-PCF cable (CS1W-CLK12-V1 or CVM1–CLK12)
GI cable (CS1W-CLK52-V1 or CVM1–CLK52)
Note 1. Always turn OFF the power to the PLC and the backup power supply be-
fore connecting the backup power supply cables.
2. Separate the backup power supply wires from other power lines and high-
voltage lines to prevent noise.
3. Always use a crimp terminal for wiring. Do not connect a wire that has only
been twisted directly to a terminal block.
4. For a higher degree of safety, it is recommended that a round crimp termi-
nal is used.
5. When mounting the crimp terminal, always use the appropriate tools for
each crimp terminal and follow the appropriate installation procedures.
Contact the crimp terminal manufacturer for details on the appropriate
tools and procedures. Failure to use the appropriate tools and procedures
could cause cables to break.
6. Measure the length of peeled cable during installation according to the
crimp terminal used and make sure that the peeled length is not too long.
Cover the compressed section of the crimp terminal and cable with vinyl
tape or heat-shrinking tube.
7. Be sure not to reverse the power supply polarity.
8. Tighten the screws on the terminal block firmly. The correct tightening
torque is 0.5 N·m. If the screws are too loose, short-circuit, malfunction or
burning may result.
9. Do not pull backup power supply cables with excessive force.
10. Do not bend backup power supply cables.
11. Do not place any object on top of backup power supply cables.
12. Supply power only after checking the wiring thoroughly.
