Cables and Terminals
It is recommended that you use flexible, thin, easy-to-bend, twisted-pair cables to
connect the terminals of the system equipment. Use solderless (crimp-on) terminals with
insulating cover, which have low contact resistance little aging.
Rigid cables make cabling work difficult and exert unnecessary force on the terminals,
which may result in system failures.
Signal Cables
• Nominal conductor cross-sectional area: 0.75 to 2.00 mm
2
Example of Suitable Cables: 600 V vinyl isolated cable (IV); JIS C 3307
Vinyl isolated wire (KIV); JIS C 3316
600 V vinyl isolated cable type 2 (HIV); JIS C 3317
Heat-proof vinyl isolated wire (UL1015/UL1007)
Vinyl isolated sheath cable for control loop (CVV);
JIS C 3401
• Solderless (crimp-on) terminal: Circular solderless terminal (for use with M4 screws)
Alarm and Control Circuit Cables
• Nominal conductor cross-sectional area: 0.5 to 1.25 mm
2
Example of Suitable Cables: 600 V vinyl isolated cable (IV); JIS C 3307
Vinyl isolated wire (KIV); JIS C 3316
Heat-proof vinyl-insulated wire (UL1007)
• Solderless (crimp-on) terminal: Circular solderless terminal (for use with M4 screws)
Power Cables
• Nominal conductor cross-sectional area
For rack-mounted AC 100-120/220-240 V-driven equipment: 1.25 to 2.0 mm
2
For rack-mounted DC 24 V-driven equipment:
Minimum 2.0 mm
2
For cabinets and console HISs:
Minimum 8.0 mm

Example of suitable cables: 600 V vinyl isolated cable (IV); JIS C 3307
Vinyl isolated wire (KIV); JIS C 3316
• Solderless (crimp-on) terminal lugs:
Circular solderless terminal lugs for M4 or M6 screw terminal
Note: Use cables capable of supplying current required by respective pieces of equipment with low voltage drop.
