machines and equipments that use reduced wiring system as well as the
suf
ficient knowledge to assemble, operate, and maintain such devices.
Before performing assembly, operation and/or maintenance, please read
this manual carefully and underst
and the contents.
Content
s

handling.
Please check that you fully understand the definitions of the following messages
( symbols ) before going on to read the body of this manual, and always follow the
instructions.
Please also read the instruction manuals etc. of related machines and equipments and
understand the contents before use.
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.
IMPOR
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 could result in
death or severe injury if you do not follow instructions.
Indicates a potentially hazardous situation that, if not avoided,
may result in minor injury or moderate injury.
NOTE
Gives you helpful information.
TANT MESSAGES
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.
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.
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.
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.
Handling precautions
Use the following UL-recognized DC power supply to combine with.
1. UL508-compatible limited voltage/current circuit
A circuit using the secondary coil of an insulating transformer that meets following conditions as power source.
Maximum voltage ( at no load ): 30Vrms ( 42.4Vpeak ) or below
Maximum current:
UL1310-compatible Class 2 power supply unit or circuit of max. 30Vrms ( 42.4Vpeak ) or
2.
less using a UL1585-compatible Class 2 transformer as power source. ( Class 2 circuit )
( 1 ) 8A or less ( including when short-circuited )
When limited by the circuit protector ( such as fuse )
( 2 )
having the following rating.
No-Load Voltage ( Vpeak ) Max. Current Rating ( A )

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 output 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.

iring ( continued )
Align with key groove, plug the
bus adapter into the communication
connector.
Tighten the lock nut by turning it
clockwise by hand, and confirm that the
connector does not move.
Connect the cables with CC-Link communication
connectors to the mating CC-Link communication
connectors ( bus adapter ) as shown below.
Cable connection
Align the key groove with the IN
connector ( plug ) of the bus adapter of
GW unit, fit on the CC-Link communication
cable ( socket ).
Tighten the lock nut on cable side by
turning it clockwise by hand.
Confirm that the connector portion does not move.
Similar to the above, connect the other
communication cable ( plug ) to the
OUT connector of the bus adapter.
If this EX500 is the terminal of CC-Link
connection, connect the terminal resistor.
Refer to "Connection of terminal resistor"
( page 12 ) in this manual.
Avoid the mixing of CC-Link dedicated high-performance cable and other cables
( CC-Link dedicated cable and/or Version 1.10 compatible CC-Link dedicated
