6. WIRING
6.1 Wiring precautions
To obtain maximum performance from the functions of AJ65SBT-64AD and
improve the system reliability, an external wiring with high durability against noise
is required.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC and AJ65SBT-64AD external input signals,
in order not to be affected by the AC side surge or conductivity.
(2) Do not bundle or place with load carrying wires other than the main circuit
line, high voltage line or programmable controller. Noises, surges, or
conductivity may affect the system.
(3) Place a one-point grounding on the programmable controller side for the
shielded line or shielded cable. However, depending on the external noise
conditions, it may be better have a grounding externally.
