Wiring precautions
(a) Use separate cables for the AC control circuit and the external input signals of the
AJ65SBT2B-64AD to avoid the influence of the AC side surges or induction.
(b) Do not install cables together with the main circuit lines, high voltage lines, or
power cables for equipment other than the programmable controller. Noise,
surges, or induction may affect the system.
(c) Ground the shielded wires or shielded cables at one point on the programmable
controller side.
However, depending on the external noise conditions, it may be better to ground
them externally.
