6. WIRING
6.1 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 AJ65SBT2B-64RD3.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC control circuit and the external
input signals of the AJ65SBT2B-64RD3 to avoid the influence of
the AC side surges and inductions.
(2) Always place the RTD at least 10cm 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 shield wire or the shield of the shielded cable must be
grounded at one end. However, Grounding outside may be suitable
depending on the noise circumstances.
6.2 Wiring with RTD
The method for connecting between the AJ65SBT2B-64RD3 and the
RTD. is shown in figure 6.1.
