Caution
Connect the cable to the connector on the body with
the wiring arranged as shown below. Proceed care-
fully, as incorrect wiring can cause damage.
Further, use DC power with sufficient capacity and a low ripple.

Be sure to read before handling. Refer to back pages 1 and 2 for Safety Instructions,
“Handling Precautions for SMC Products” (M-E03-3) for Common Precautions.
A right angle type cable is also
available. The entry direction
for the right angle type con
-
nector is to downwards (SUP
port side).
Never turn the connector as it
is not designed to turn. Using
force to turn the connector will

Series ITV0000/009 Precautions
1. Do not use a lubricator on the supply side of this product, as
this can cause malfunction. When lubrication of the terminal
equipment is necessary, connect a lubricator on the output
side of this equipment.
2. If electric power is shut off while pressure is being applied,
pressure will be retained on the output side.
However, this output pressure is held only temporarily and is not gua-
ranteed.
If exhausting of this pressure is desired, shut off the power
after reducing the set pressure, and discharge the air using a residual
pressure exhaust valve, etc.
3. If power to this product is cut off due to a power failure, etc.
when
it is in a controlled state, output pressure will be retai-
ned temporarily. Handle carefully when operating with output
pressure released to the atmosphere, as air will continue to
flow out
.
4. If supply pressure to this product is interrupted while the power
is
still on, the internal solenoid valve will continue to operate
and a humming noise may be generated.
Since the life of the product may be shortened, shut off the power
supply also when supply pressure is shut off.
5. This product is adjusted for each specification at the time of
shipment from
the factory. Avoid careless disassembly or remo-
val of parts, as this can lead to malfunction.
6. The optional cable connector is a 4 wire type. When the moni-
tor output (analogue output or switch output) is not being
used, keep it from touching the other wires as this can cause
malfunction.
7. Please note that the right angle cable does not rotate and is li-
mited to only one entry direction.
8. Take the following steps to avoid malfunction due to noise.
1) Remove power supply noise during operation by installing a line fil-
ter, etc. in the AC power line.
2) For avoiding the influence of noise or static electricity, install this
product and its wiring as far as possible from strong electric fields
such as those of motors and power lines, etc.
3) Be sure to implement protective measures against load surge for in
-
duction loads (solenoid valves, relays, etc.).
9. The product characteristics are confined to the static state.
The pressure may not reach the set pressure and the life of
the product may extremely be shortened with buzzing of the
solenoid valve when air is consumed on the output side, es-
pecially when it is used with a system which has a large
amount of leakage.
10. For details on the handling of this product, refer to the
instruction manual which is included with the product
.
11. In locations where the body is exposed to water, dust,
etc., there is a possibility that moisture or dust could
enter the body through the breathing hole.
Mount a fitting and tube (M-3AU-3 fitting and
TIU01m-mm tube recommended) onto the breat-
hing hole and run the tube to a location not expo-
sed to moisture or dust, etc.
12. If this product will be used in a sealed environment, such as in -
side an inspection box, a ventilation fan should be installed to
ensure adequate ventilation as this product can generate heat
in some operating conditions.
When the power is turned on, a noise may be generated as a
means of checking the operating condition of the solenoid
valve. This noise is normal and does not indicate a fault.

1. Install an air filter near this product on the supply side.
Select a filtration degree of 5 µm or less.
2. Compressed air containing large amounts of drainage
can cause malfunction of this product and other pneu-
matic equipment. As a countermeasure, install an af-
tercooler, air dryer or Drain Catch, etc.
3. If large amounts of carbon dust are generated by the
compressor, it can accumulate inside this product and
cause malfunction.
For details on the above compressed air quality, refer
to SMC's "Air Preparation Systems".

Specific Product Precautions 2
1. Screw piping together with the recommended proper
torque while holding the side that has female threads.
Looseness or faulty sealing will occur if tightening torque is in-
sufficient, while thread damage will result if the torque is ex-
cessive. Furthermore, if the side with the female threads is not
held while tightening, excessive force will be applied directly to
the piping brackets, etc. causing damage or other problems.
2. Do not allow twisting or bending moment to be ap-
plied other than the weight of the equipment itself.
Provide separate support for external piping, as damage may
otherwise occur.
3. Since excessive moment loads and the propagation
of vibrations, etc. can easily result from inflexible
piping made of materials such as steel, avoid these
problems by using flexible tubing for intermediate
connections.
Piping
Warning
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and ot-
her debris from inside the pipe.
2. Wrapping of pipe tape
When screwing together pipes and fittings, etc., be sure that
chips from the pipe threads and sealing material do not get in-
side the piping.
Also, when pipe tape is used, leave 1.5 to 2 thread ridges ex-
posed at the end of the threads.

Caution
1. Do not operate in locations having an atmosphere
of corrosive gases, chemicals, sea water, or where
there will be contact with them.
2. Do not operate in locations where vibration or im-
pact occurs.
Operating Environment
1. Employ suitable protective measures in locations
where there is contact with water droplets, oil or
welding spatter, etc.
2. Consult with
SMC when used in power plants, or if
instrumentation related.

1. In locations where the body is exposed to water,
steam, dust, etc., there is a possibility that moisture
or dust could enter the body through the EXH (sole-
noid) ports, thereby causing problems.
2. To overcome this, simply install tubing to each port,
using the fittings, and extend the tubing so that the
other end is at a location where no water splash,
etc. occurs. Make sure not to bend, or block the I.D.
of the tubing as this
will have a detrimental effect
on the pressure control.
3.
Do not operate in locations where vibration or im-
pact occurs.
4. In locations which receive direct sunlight, provide a
protective cover, etc.
5.
In locations near heat sources, block off any radia-
ted heat.
6. In locations where there is contact with spatter from
water, oil or solder etc., implement suitable protecti-
ve measures.
1. Install an air filter near this product on the supply
side. Select a filtration degree of 5
µm or less.
2. Compressed air containing large amounts of drai-
nage can cause malfunction of this product and ot-
her pneumatic equipment. As a countermeasure,
install an aftercooler, air dryer or Drain Catch, etc.
3. If large amounts of carbon dust are generated by
the compressor,
it can accumulate inside this pro-
duct and cause malfunction. For details on the abo-
ve compressed air quality, refer to SMC's "Air Pre-
paration Systems".
Be sure to read before handling. Refer to back pages 1 and 2 for Safety Instructions,
“Handling Precautions for SMC Products” (M-E03-3) for Common Precautions.
