The wiring precautions and examples of module connection are provided below.
In order to optimize the functions of the D/A 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
D/A converter module to avoid the influence of the AC side surges and inductions.
(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 programmable controller. This
may increase the effects of noise, surges and induction.
(3) Perform a 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.
POINT
When using Q68DAVN, Q68DAIN, Q68DAV or Q68DAI, if it is difficult to wire FG
terminals due to the limited installation space, use FG terminal L-shaped metal
fitting.
