2. WIRING
To prevent electric shock or instrument failure, do not turn on the
power until all the wiring is completed.
2.1 Wiring Cautions
• To avoid noise induction, keep communication signal wire away from instrument
power line, load lines and power lines of other electric equipment.
• If there is electrical noise in the vicinity of the instrument that could affect
operation, use a noise filter.
− Shorten the distance between the twisted power supply wire pitches to
achieve the most effective noise reduction.
− Always install the noise filter on a grounded panel. Minimize the wiring
distance between the noise filter output and the instrument power supply
terminals to achieve the most effective noise reduction.
− Do not connect fuses or switches to the noise filter output wiring as this will
reduce the effectiveness of the noise filter.
• Power supply wiring must be twisted and have a low voltage drop.
• For an instrument with 24 V power supply, supply power from a SELV circuit.
• A suitable power supply should be considered in the end-use equipment. The
power supply must be in compliance with a limited-energy circuits (maximum
available current of 8 A).
• Use the solderless terminal appropriate to the screw size (M3).

The CC-Link connecting terminal cannot do on-line installation or
dismount for terminal block of dismount impossibility. The device
cannot be replaced unless the link is set off-line. In addition, FG (flame
ground) terminal of terminal number 5 is FG in a CC-Link function, and
it is not FG of instrument all.
Ground both ends of the shield wire on the twisted pair cable via the
SLD or FG terminal of each module. In addition, the SLD terminal is
internally connected with the FG terminal.
Do not ground the instrument together with other equipment.
In addition, use grounding wires with across section of 2.0 mm2 or
more. (Ground resistance: 100 ohm or less)

1 station occupied 1 time 2 channels
4 stations occupied 1 time 16 channels
4 stations occupied 2 times 32 channels
4 stations occupied 4 times 64 channels
* The number of channels used depends on the data type.
On a Z-TIO module (4-channel type), four channels are used if the data is channel data; however,
only one channel is used if the data is module data.
For example, when 16 Z-TIO modules (4-channel type) are connected, 64 channels are used for
channel data, or 16 channels are used for module data.
In the case of 1 station occupied 1 time, the maximum number of CC-Link
assignment channels is two channels, and thus it may not be possible to
use the amount of data of one module, depending on the data type. For
this reason, caution is necessary when using 1 station occupied 1 time.
[Example] When one Z-TIO module (4-channel type) is connected, CH3
and CH4 data cannot be used.
