understand the contents before use.

IMPORTANT MESSAGES

Indicates a potentially hazardous situation that could result in

death or severe injury if you do not follow instructions.

Read this manual and follow its instructions. Signal words such as WARNING,

CAUTION and NOTE will be followed by important safety information that must be

carefully reviewed.

Indicates a potentially hazardous situation that, if not avoided,

may result in minor injury or moderate injury.

Gives you helpful information.

NOTE

Do not disassemble,

modify ( including modification of printed circuit board ) or repair.

Otherwise injury or failure can result.

Do not operate beyond specification range.

Otherwise fire, malfunction or damage to the reduced wiring system can result.

Confirm the specifications before operation.

Do not operate in atmosphere of flammable/explosive/corrosive gas.

Otherwise fire, explosion or corrosion can result.

This reduced wiring system is not explosion-proof type.

For use in interlock circuit:

Provide double interlock system by adding different type of protection

( such as mechanical protection ).

Check that the interlock circuit is working normally.

Otherwise accident caused by malfunction can result.

Before performing maintenance:

Turn off power supply.

Stop air supply, exhaust compressed air in piping, and confirm the release to

atmosphere.

Otherwise injury can result.

Conduct proper functional inspection after completing maintenance.

In the case of abnormality such as unit does not work normally, stop the operation.

Otherwise safety cannot be assured due to unintended malfunction.

Avoid mixing of CC-Link dedicated high-performance cable and other cables (

CC-Link dedicated cable and/or Version 1.10 compatible CC-Link dedicated

cable ).

Mixing can hinder normal data transmission and cause trouble.

Provide grounding to improve safety and noise resistance of reduced wiring sys-

tem.

Provide grounding as close to the unit as possible to shorten distance for grounding.

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.

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.

Power supply wiring

Connect the power supply connector cable to the power supply connector of GW unit.

There are two types of cables different in connector shape ---- straight type and angle

type. With this cable, the power is supplied to the output devices such as solenoid

valve, and the input devices such as sensor, and for controlling GW/SI. Therefore, there

is no need to supply the power to other units individually.

When selecting the power supply, refer to "Handling precautions" ( page 3 ) in this manual.

Cable connection

Align the key groove with the power supply

connector ( plug ) of GW unit, plug in the power

supply cable ( socket ).

Tighten the lock nut on cable side by turning it

clockwise by hand.

Confirm that the connector portion does not move.
