3 Installation
3.1 Installation Warning
Do not install the product unless the safety instructions have been
read and understood.
Do not use the product in excess of its allowable specification as
listed in Section 2.
When installing, inspecting or performing maintenance on the product,
be sure to turn off the power supplies. Then, lock it so it cannot be
tampered with while work is happening.
Keep the flatness of the mounting surface to 0.1 mm maximum.
Insufficient flatness of a work piece or actuator mounting surface can
cause play in the guide and increased sliding resistance. In the case
of overhang mounting (including cantilever), use a support plate or
support guide to avoid deflection of the actuator body.
When mounting the actuator, use all mounting holes.
If all mounting holes are not used, this will not maintain the specified
performance. e.g. the amount of displacement of the table will
increase.
When mounting the actuator, use screws with adequate length and
tighten them with adequate torque.
Tightening the screws with a torque higher than recommended may
cause malfunction, whilst tightening with a torque lower than
recommended can cause displacement of the mounting position, or in
extreme conditions the actuator could become detached from its
mounting position.
Note1) When A is M thread, L is thread depth.
In order to prevent the work piece fixing screws from damaging the
table, use screws at least 0.5 mm shorter than the maximum thread
depth.
Longer screws can hit the body and cause operation failure.
When mounting the actuator using the body mounting reference
plane, use a positioning pin.
Set the height of the pin to be 5 mm or more because of R
chamfering. (recommended height: 6 mm).
3 Installation - continued
3.2 Environment Warning
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
Do not use in an explosive atmosphere.
Do not expose to direct sunlight. Use a suitable protective cover.
Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
Do not mount in a location exposed to radiant heat that would result
in temperatures in excess of the product’s specifications.
Prevent foreign particles from entering the product.
3.3 Mounting Warning
Observe the required tightening torque for screws.
Unless stated otherwise, tighten the screws to the recommended
torque for mounting the product.
Do not make any alterations to the product.
Alterations made to this product may lead to a loss of durability and
damage to the product, which can lead to injury and damage to other
equipment and machinery.
When an external guide is used, connect the moving parts of the
product and the load in such a way that there is no interference at
any point within the stroke.
Do not scratch or dent the sliding parts of the table or mounting face
etc., by striking or holding them with other objects. The components
are manufactured to precise tolerances, so that even a slight
deformation may cause faulty operation or seizure.
Do not use the product until it has been verified that the equipment
can be operated correctly.
After mounting or repair, connect the power supply to the product and
perform appropriate functional inspections to check it is mounted
correctly.
Do not use the product until it has been verified that the equipment
can be operated correctly.
After mounting or repair, connect the power supply to the product and
perform appropriate functional inspections to check it is mounted
correctly.
Maintenance space
Allow sufficient space for maintenance and inspection.
3.4 Lubrication Caution
SMC products have been lubricated for life at manufacture, and do
not require lubrication in service.
If a lubricant is used in the system, refer to catalogue for details.
The recommended grease is lithium grade No.2
SMC grease packs are listed below.

3.5 Wiring Warning
Adjustment, mounting or wiring changes should not be carried out
before disconnecting the power supply to the product.
Electric shock, malfunction and damage can result.
Do not disassemble the cables.
Use only specified cables.
Use only specified cables otherwise there may be risk of fire and
damage.
Do not connect or disconnect the wires, cables and connectors when
the power is turned on. Caution
Wire the connector correctly and securely.
Check the connector for polarity and do not apply any voltage to the
terminals other than those specified in the Operation Manual.
3 Installation - continued
Take appropriate measures against noise.
Noise in a signal line may cause malfunction. As a countermeasure
separate the high voltage and low voltage cables, and shorten the
wiring lengths, etc.
Do not route input/output wires and cables together with power or
high voltage cables.
The product can malfunction due to noise interference and surge
voltage from power and high voltage cables close to the signal line.
Route the wires of the product separately from power or high voltage
cables.
Take care that actuator movement does not catch cables.
Operate with all wires and cables secured.
Avoid bending cables at sharp angles where they enter the product.
Avoid twisting, folding, rotating or applying an external force to the
cable.
Risk of electric shock, wire breakage, contact failure and loss of
control of the product can result.
Select “Robotic cables”in applications where cables are moving
repeatedly (encoder/ motor/ lock).
Refer to the relevant operation manual for the bending life of the
cable.
Confirm correct insulation.
Poor insulation of wires, cables, connectors, terminals etc. can cause
interference with other circuits. Also there is the possibility that
excessive voltage or current may be applied to the product causing
damage.
Refer to the auto switch references in “Best Pneumatics“ when an
auto switch is to be used
LECSA (Pulse input / Positioning) driver
3 Installation - continued
3.6 Operating precautions
Do not touch the motor whilst it is in operation. The surface
temperature can increase to approximately 80°C. Energising alone
can also increase the temperature of the product. These
temperatures can cause burns.
If the product is overheating, smoking or has caught fire, immediately
shut the power supply off.
If the product emits abnormal noise or vibrations, the product should
be immediately stopped and inspected as it may be mounted
incorrectly, otherwise it can seriously damage the product.
Do not touch rotating parts of the motor or moving parts of the
actuator while in operation.
4 How to Order
For standard products, refer to the catalogue for the how to order
information.
For special products, which include a suffix of “-X*”, “-DC*” or “-DK*”,
then please refer to the customer drawing of that specific product.
5 Outline Dimensions (mm)
For standard products, refer to the catalogue for outline dimensions.
For special products, which include a suffix of “-X*”, “-DC*” or “-DK*”,
then please refer to the customer drawing of that specific product.
6 Maintenance
6.1 General Maintenance Caution
Not following proper maintenance procedures could cause the
product to malfunction and lead to equipment damage.
If handled improperly, compressed air can be dangerous.
Maintenance of pneumatic systems should be performed only by
qualified personnel.
Before performing maintenance, turn off the power supply and be
sure to cut off the supply pressure. Confirm that the air is released to
atmosphere.
After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
If any electrical connections are disturbed during maintenance,
ensure they are reconnected correctly and safety checks are carried
out as required to ensure continued compliance with applicable
national regulations.
Do not make any modification to the product.
Do not disassemble the product, unless required by installation or
maintenance instructions.
Incorrect handling can cause an injury, damage or malfunction of the
equipment and machinery, so ensure that the procedure for the task
is followed.
Always allow sufficient space around the product to complete any
maintenance and inspection.
