4.4 Wiring
The wiring precautions and examples of module connection are provided below.
4.4.1 Wiring precautions
In order to optimize the functions of the A/D converter 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 the AC control circuit and the external input signals of the
Q68AD-G to prevent influences of AC surge or induction.
(2) Use separate cables for the AC control circuit, the external input signals and external
power supply of the Q66AD-DG to avoid influences of AC side surge or induction.
(3) Keep a distance among the main circuit line, a high-voltage cable and a load cable
from other than the programmable controller.
Failure to do so may increase the effects of noise, surges and induction.
(4) The shield wire or the shield of the shielded cable must be grounded at one end.
(5) When wiring to the module placed on the right side of the Q66AD-DG is difficult,
remove the Q66AD-DG before wiring.
