3 Installation
Warning
• Do not install the product unless the safety instructions have been read
and understood.
• Do not use the product outside of the allowable specifications.
• Ensure the product is sized correctly and is suitable for the application.
• Do not operate the product by fixing the piston rod and moving the
actuator body.
• Keep the flatness of the mounting surface to within 0.02 mm maximum
when mounting the actuator or work piece.
Insufficient flatness of the work piece or the surface onto which the
actuator body is to be mounted can cause increased sliding resistance,
noise, or life time reduction.
• 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 or workpiece, use screws with adequate
length, but with length less than the maximum thread depth. The use
of screws that are too long can touch the body and cause malfunction.
• Tigthen screws to the recommended tightening 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
dropping of the work piece.
• Avoid using the LE2YG series actuator in such a way that rotational
torque is applied to the plate end.
Excessive torque could cause the guide rod and bushing to be
deformed, causing looseness of the guide or increase in sliding
resistance. The applied rotational torque [N•m] should be less than in
the table below.

• When using an auto switch with the guide rod type LE2YG series, the
following limits will apply.
1) Insert the auto switch from the front side with rod (plate) protruding.
2) Auto switches with perpendicular cable entry cannot be used.
3) For parts hidden by the guide attachment (rod protruding end) an
auto switch cannot be fixed.
4) Consult with SMC when using an auto switch on the rod protruding
end.
3.1 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.
• Avoid use in the following environments:
1. Locations where a large amount of dust and cutting chips are
airborne.
2. Locations where the ambient temperature is outside the range of
the temperature specification (refer to specifications).
3. Locations where the ambient humidity is outside the range of the
humidity specification (refer to specifications).
4. Locations where strong magnetic or electric fields are generated.
5. Locations where direct vibration or impact is applied to the product.
6. Areas that are dusty, or are exposed to splashes of water and oil
drops.
7. At an altitude of 1000 meters or higher. Heat dissipation and
withstand voltage will decrease. Contact SMC for further details.
• Do not use in an environment where the product is directly exposed to
liquid, such as cutting oils.
3. Installation (continued)
• Install a protective cover when the product is used in an environment
directly exposed to foreign matter such as dust, cutting chips and
spatter.
3.1 Lubrication
Caution
• The product has been lubricated for life at manufacture and does not
require lubrication in service. If a lubricant is to be used, contact SMC.
3.2 Mounting
Warning
• 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.
• When mounting the actuator or attaching the work piece, do not apply
strong impact or large moment.
If an external force over the allowable moment is applied, it may cause
300
looseness in the guide unit, an increase in sliding resistance or other
problems.
-
• Allow sufficient space for maintenance and inspection.
1.36
• The electric actuator and its peripheral devices should be installed on
1.88
a fire-proof material.
-
Direct installation on or near a flammable material may cause a fire.
1.44
2.32
• Take measures to ensure that the operating temperature of the
actuator and its peripheral devices are within the range of the
specifications.
The actuator should be installed with 50 mm or more space between
each side of it and other equipment or components.
• Do not mount the controller or its peripheral devices near a large
electromagnetic contactor or non fused breaker which generate
vibration on the same panel. Mount them on different panels, or keep
the controller and its peripheral devices away from a vibration source.

4 Wiring
4.1 Wiring
• 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.
• 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.
• 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.
• Take care that actuator movement does not catch cables.
• Avoid bending cables at sharp angles where they enter the product.
Avoid twisting, folding, rotating or applying an external force to the
cable.
• Do not allow the cable near to the actuator to move repeatably. The
motor cable is not a robotic type cable. Secure the cable between the
actuator and the connector to prevent movement.
•
When the actuator cable is bent repeatedly, do not store them in a
Max. thread length movable wiring duct smaller than the specified bending radius (for
] [mm]
cable lengths up to 10 m: bend radius = 56 mm min.; for cable lengths
