Wiring Diagram 1
According to our noise tests, the attachment of a ferrite core improves
noise voltage by 650~900V and aids in preventing communication errors.
Note
In case of direct connection with the CPU port of A/QnA series, be sure to attach the
ferrite core to the cable between POD and the CPU port of A/QnA series for noise.
A Ferrite core is sold as an optional accessory.
A noise filter(ferrite core) is sold as an optional accessory. When you buy it, specify
“ZCAT032-0930” as the model name.
In consideration of such noise problems, it is recommended that the standard type link
unit be used in such a case when the cable length of more than 15m is required.
