5. Wiring
The precautions for wiring and an example of module connection are given in this
section.
5.1 Precautions for wiring
External wiring that is not easily affected by noise is a prerequisite for using the
A1S64AD functions to the fullest and creating a highly reliable system.
The precautions for external wiring are given below.
(1) Use separate cables for the alternating current and A1S64AD external input
signals to eliminate the effect of surge or inductance on the alternating current
side.
(2) Do not lay the wires or bundle the wires with the main circuit wires, high voltage
wires or the load wire other than that from the PLC. Failure to observe this will
increase the effect of noise, surge and inductance.
(3) Ground the shield of a shielded wire or shielded cable to one point on the PLC
side.
