6. WIRING
6.1 Wiring Precautions
To obtain the maximum performance from the functions of the
AJ65SBT2B-64AD and improve the system reliability, an external wiring
with high durability against noise is required.
Precautions for external wiring are as follows:
(1) 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.
(2) 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.
(3) 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.
