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 the Q68TD-G-H02(H01).
(1) Use separate cables for the AC control circuit and the external input
signals of the Q68TD-G-H02(H01) to avoid the influence of the AC side
surges and inductions.
(2) Always place the thermocouple 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.
