Precautions Regarding Analog Output Wring
For the analog output wiring, always use double-core twisted-pair shielded wires.
Ground the shielding of the shielded wires at the side of the load devices. However,
depending on the conditions of the external noise, it may be necessary to ground
externally, or leave the shielding open.
Do not have the analog output wiring close to AC wires, power wires, or load wires from
sources other than the PLC.
The terminals marked with a dot on the input and output terminal blocks are not to be
used. However, they may be connected to circuits internally, so be sure not to connect
any wiring to them.
