Explanation diagram
The electric wire sizes are specified by recommended electric wire sizes (FLSC electric wires) in the
case of atmospheric temperature of 40°C or lower in Chapter 4. When significantly different electric
wire sizes or cabtire cables/shielded wires are used, wiring length should be reconsidered as inductance
of power line change.
In identical power line size in cabtire radio shield wire, a long power line with approximately 3 times
the length shown in the chart should be used.
