4.4.1 Wiring precautions
In order to optimize the functions of the A/D conversion module and ensure system
reliability, external wiring that is protected from noise is required.
Please observe the following precautions for external wiring:
(1) Use separate cables for alternating current and external input signals for Q64AD
and Q68ADV (I) in order to avoid A/C surges and induction effects.
(2) Do not mount the cables close to or bundle them with the main circuit line, a high-
voltage cable or a load cable from other than the PLC. This may increase the
effects of noise, surges and induction.
(3) Perform an one-point grounding for shielded lines and the shields of sealed
cables.
(4) A solderless terminal with insulating sleeve cannot be used for the terminal block.
Covering the cable-connection portion of the solderless terminal with a marked
tube or an insulation tube is recommended.
