The wiring precautions and examples of module connection are provided below.
In order to optimize the functions of the Q64RD 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
Q64RD to avoid the influence of the AC side surges and inductions.
(2) Do not run the module cables near, or bundle them with, the main circuit and high-
voltage cables and the load cables from other than the PLC.
Not doing so will make the module more susceptible to noises, surges and
inductions.
(3) Earth the shielded wire or shielded cable to FG of the PLC. However, depending
on the external noise conditions, external earthing may be recommended.
(4) Insulation-sleeved crimping terminals cannot be used with the terminal block.
It is recommended to fit mark tubes or insulation tubes to the wire connection
parts of the crimping terminals.
