5-2-4 Precautions for wiring of USER IO PORT
For wiring of USER IO PORT, you are recommended to follow the procedure below since noise may be
caused.
(1) Use of a twisted shield pair wire
(2) Insulation of signals by photocouplers etc. on the side of external connection devices
(3) Signal wires shall be arranged without tying with a power line.
(4) Connection in the shortest distance
