SAFETY ( continued )
Follow the instructions given below when handling your reduced wiring system.
Otherwise a damage or failure to cause a malfunction can result.
Operate the reduced wiring system at the specified voltage.
Reserve space for maintenance.
Do not remove any name plate or label.
Do not drop, hit or apply an excessive shock to the unit.
Follow the specified tightening torque.
Do not apply any excessive force to cables by repeated bending, tensioning or placing a
heavy object on the cables.
Connect wires and cables correctly.
Do not perform any wiring work while the power is on.
Do not use the reduced wiring system on the same wiring route as the power line or high
voltage line.
Confirm the insulation of wiring.
Perform the power supply wiring by dividing into two lines ---- one is for power supply for out-
put and the other is for power supply for input and controlling GW/SI.
Take sufficient measures against noise such as noise filter when incorporating the reduced
wiring system into a machine or equipment.
Connect the shield wire of the dedicated cable for CC-Link to "SLD" of each unit.
Mount a terminal plug or a waterproof cap on each unused M12 connector for input/output
( communication connector, communication ports A - D, and power supply for input and
controlling GW/SI ).
Take sufficient shielding measures when operating the product in any of the following places.
( 1 ) A place where noise due to static electricity etc. is generated
( 2 ) A place of high electric field strength
( 3 ) A place where exposure to radioactivity is possible
( 4 ) A place near power cable
Do not operate the product in a place where there is a source of surge.
Use a surge absorbing element built-in type to directly drive the load that generates surge
voltage such as solenoid valve.
Prevent any foreign matter such as remnant of wires from getting inside the product when
opening the station number switch protective cover.
Install the reduced wiring system in a place free from vibration and impact.
Operate the product in the specified ambient temperature range.
Do not use in a place to be affected by the radiant heat from a surrounding heat source.
Set the DIP switch and rotary switche by using a sharp-pointed watchmakers screwdriver
etc.
Perform the maintenance regularly.
Conduct an appropriate functional inspection after completing the maintenance.
Do not use chemicals such as benzin and thinner to clean the product.

The reduced wiring system is connected to various kinds of fieldbus and realizes the
reduced wiring and decentralized installation of I/O devices . The signals to/from
fieldbus are exchanged by GW unit, and the signals to/from decentralized I/O devices
are collected and delivered by GW unit.
The maximum number of connections of manifold valve/Input unit manifold is
16/branch x 4 branches = 64 points each for output and input.
As the cables with connectors are used for all wiring between devices, the system
complies with the IP65 environment.
