5.1 Wiring Precautions

External wiring that is less susceptible to noise is required as a
condition of enabling a highly reliable system and making full use of the
capabilities of Q68RD3-G.
(1) Use separate cables for the AC control circuit and the external
input signals of the Q68RD3-G to avoid the influence of the AC side
surges and inductions.
(2) Always place the RTD at least 100mm away from the main circuit
cables and AC control circuit lines. Fully keep it away from high-
voltage cables and circuits, which include high frequency waves,
such as an inverter's load circuit. Not doing so will cause the
module more susceptible to noises, surges and inductions.
(3) The following wiring is required for the product to comply with the
EMC and Low Voltage Directives.
(a) Use shielded cables for every external wiring and use the
