•Use the specified voltage.
Otherwise failure or malfunction can result.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
•Do not remove any nameplates or labels.
This can lead to incorrect maintenance, or misreading of the operation manual, which could cause damage or
malfunction to the product.
It may also result in non-conformity to safety standards.
•Product handling
∗Installation
•Do not drop, hit or apply excessive shock to the fieldbus system.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP65/67 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
∗Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the fieldbus system and/or I/O device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the fieldbus system and/or I/O device can malfunction due to interference of noise and surge voltage
from power and high voltage cables to the signal line.
Route the wires (piping) of the fieldbus system and/or I/O device separately from power or high voltage cables.

-6No.EX##-OMO0019
∗Environment
•Select the proper type of protection according to the environment of operation.
IP65/67 protection is achieved when the following conditions are met.
(1) The units are connected properly with fieldbus cable with M12 connector and power cable with M12 (M8)
connector.
(2) Suitable mounting of each unit and manifold valve.
If using in an environment that is exposed to water splashes, please take measures such as using a cover.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even
for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace,
motor, etc.) close to the fieldbus system, this may cause deterioration or breakage of the internal circuit of the
fieldbus system. Avoid sources of surge generation and crossed lines.
•When a surge-generating load such as a relay or solenoid is driven directly, use an fieldbus system with
a built-in surge absorbing element.
Direct drive of a load generating surge voltage can damage the fieldbus system.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
•Prevent foreign matter such as remnant of wires from entering the fieldbus system to avoid failure and
malfunction.
•Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.
•Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.

If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
•Keep within the specified ambient temperature range.
Otherwise malfunction can result.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
∗Adjustment and Operation
•Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
•Please refer to the PLC manufacturer's manual etc. for details of programming and addresses.
For the PLC protocol and programming refer to the relevant manufacturer's documentation.
∗Maintenance
•Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
•Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
•After maintenance is complete, perform appropriate functional inspections.
Stop operation if the equipment does not function properly.
Otherwise safety is not assured due to an unexpected malfunction or incorrect operation.
•Do not use solvents such as benzene, thinner etc. to clean the each unit.
They could damage the surface of the body and erase the markings on the body.
Use a soft cloth to remove stains.
For heavy stains, use a cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the stains
again with a dry cloth.

Mounting and Installation
■Installation
The mounting and removing methods of SI unit are as shown below.
NOTE
Holding with hand so that there will be no gap between SI unit and Air supply/exhaust block assembly,
tighten the bolts. Be sure to tighten each bolt by specified tightening torque.
(Tightening torque: 0.6 Nm)
∗1: For branch wiring method, refer to subsection "Wiring" (page 10) of section "EX500 GW unit" in this manual. As the power to output
devices such as solenoid valve is supplied by branch wiring (branch cable with M12 connector), there is no need to supply power
individually.
∗2: For mounting/installation methods of solenoid valve, manifold, etc., refer to the catalogs, instruction manuals, technical data, etc. of
each valve series. When connecting general purpose output block only, refer to subsection "Mounting and installation" (page 43) of
section "EX9 Series General Purpose Output Block" in this manual.

○Output number assignment
∗: The output number refers to the D side solenoid position on the manifold and starts at zero.
∗: Standard wiring on the manifold is for double-solenoid valves and output number starts A side and B side in that order as shown in
the figure a.
If you mount a single-solenoid valve on the standard wiring manifold, output number for B side valve is skipped.
∗: Custom wiring for mixed mounting single-solenoid valves and double-solenoid-valves can be specified with a Wiring Specification
Sheet. Example wiring is shown in the figure b.

Summary of Product parts
The EX9 series general purpose output block is the unit to operate solenoid valve, relay, etc. in combination
with SY/SV/VQC/S0700 series valve and applicable SI unit.
There are two types ---- one type is for low wattage load (EX9-OET1 or EX9-OET2) that outputs signals by
receiving power supply from SI unit, and the other type is for high wattage load (EX9-OEP1 or EX9-OEP2)
that outputs signals by receiving power supply from outside. The type for high wattage load is used in
combination with the power block (EX9-PE1) connected with external power supply. As the low-wattage-load
type is powered from SI unit, the wattage of load is limited to 1.0 W ∗1. For a load up to 12 W, use the power
block and the high-wattage-load type.
For output block and power block specifications, refer to the manual. (EX##-OMH0005)
