5.1 Cautions on Wiring
To establish a highly reliable system by making the best use of the
A1S68AD functions, external wiring that is not susceptible to the effects
of noise is required.
The cautions on external wiring are presented below:
(1) Use separate cables for AC input current and external input signals to the
A1S68AD. This can prevent the effects of surge or induction of the AC
input current.
(2) Keep the external wiring at lease 10cm away from the main circuit, high-
voltage wires or load-carrying wires other than those extending from the
PLC: otherwise, the wiring will be affected by noise, surge or induction.
(3) Generally, ground the shielded wire or shielded cable at one point on the
PLC CPU. However, depending on the external noise level, it may be
advisable to ground it an external location.
