3.2 Wiring Precautions
1) The total length of the high-speed I/O cables should be within 3.0 m.
2) Do not bundle the extension cable together with power cables (high voltage,
large current) which produce strong interference signals. Separate it from other
cables and avoid cabling in parallel.
3) Select recommended cables and pinboards for connection. It is recommended
that shielded cables be used as extension cables to enhance capacity of resisting
interference.
4) When laying the extension cable, make sure that the minimum bending radius
of the cable is more than 76 mm. When the bending radius is 76 mm, malfunction
may occur due to poor performance or disconnection.
