Caution in Handling

1. Handling of the Packed Product

Especially in the transportation and handling do not damage or drop as much as possible.

• An operator should never attempt to carry a heavy package on their own.

• If the shipping box is to be left standing, it should be in a horizontal position.

• Do not step or sit on the package.

• Do not put any load that may cause a deformation or breakage of the package.

2. Handling in Unpacked Condition

[RA4R, RA6R, RA7R, RA8R, RA10R]
Do not carry an actuator by motor unit and a track cover area and the cable or attempt to move it by
pulling the cable.

• Hold the body base when transporting the actuator out the package.

• Do not hit or drop the product while carrying. Especially, pay attention to the side cover.

• Do not give any excessive force to any of the sections in the actuator.

• When transporting an actuator, check the weight and the center of gravity of the actuator in

instruction manual before lifting up on a crane. Pay attention to the center point of gravity as it
differs for each model.

Installation and Storage • Preservation Environment

1. Installation Environment

Do not use this product in the following environment.
In general, the installation environment should be one in which an operator can work without protective
gear.
Also make sure to keep enough work space necessary for maintenance.

• Location exposed to radiant heat from a huge heat source such as the heat treatment

• Location where the surrounding air temperature exceeds the range of 0 to 40°C

• Location where condensation occurs due to abrupt temperature changes

• Location where relative humidity exceeds 85%RH

• Location exposed to direct sunlight

• Location exposed to corrosive gases or combustible gases

• Location exposed to significant amount of dust, salt or iron powder (outside of ordinary assembly

plant)

• Location where water, and oil (includes oil mist and cutting fluid) or chemical is splashed

• Location where the product main body receives vibration or hit impact

• Location where the altitude of 2,000m or more

When using the product in any of the locations specified below, provide a sufficient shield.

• Place subject to electrostatic noise

• Location where exposed to the influence of strong electric or magnetic field

• Location where exposed to the influence of ultraviolet or radiant rays

2. Storage • Preservation Environment

• The storage and preservation environment should comply with the same standards as those for
the installation environment.

• In particular, when the machine is to be stored for a long time, pay close attention to
environmental conditions so that no dew condensation forms. Unless specially specified,
moisture absorbency protection is not included in the package when the machine is delivered.

• In the case that the machine is to be stored and preserved in an environment where dew
condensation is anticipated, take the condensation preventive measures from outside of the
entire package, or directly after opening the package.

• For storage and preservation temperature, the machine withstands temperatures up to 60°C for
a short time, but in the case of the storage and preservation period of 1 month or more, control
the temperature to 50°C or less. Storage and preservation should be performed in the horizontal
condition. In the case it is stored in the packaged condition, follow the posture instruction if any
displayed on the package.

Attachment

Refer to the Instruction Manual (DVD) for the attachments of the actuator and loads.

[Precautions for Attachments]

No. Item Precautions

1 Installation

• Avoid using an actuator equipped with no brake when installing in
vertical orientation

2 Attachment surface

• The base has to have a structure with sufficient rigidity to prevent
oscillation.

• Other than RA15R, RA20R the side and bottom surfaces of the base
on the actuator work as the datum surfaces for the side of the rod.

In

case operation accuracy is required, utilize these surfaces for
installation.

• The actuator mounting surface and other surfaces that are used as a
datum should be flat enough with an accuracy of machining or
equivalent treatment, and the flatness of the mounting surface needs
to be 0.05mm/m or less.

• Secure the space where maintenance work can be performed.

3 Bolts to be used

• For the bolts to be used, a high-tensile bolt complying with ISO-10.9
or more is recommended.

• If using the tapped holes, use screws with the thread length
dimension being less than the effective depth of the holes.

• In case the tapped hole is a through hole, be careful so the screw tip
does not exceed the surface of the tapped hole.

• For the actuator mounting, use a bolt with the dimension of its
effective mating length to the tapped hole size as stated below.
When tapped hole is on female
→ thread length same as nominal diameter.
When tapped hole is on aluminum
→ thread length 1.8 times longer than nominal diameter
However, when installing with using tap holes on actuator, set the
RCS3-RA8R is 12mm or less, and RCS3-RA10R is 15mm or less.
When installing with using front bracket, set the RCS3-RA15R,
RA20R is 18mm or less.

4 Attachment of tool for tip

of the loadcell
(prepared by user)

• Make the weight of the tool lower than the transportable weight of the
actuator.

• When attaching a tool, pay attention not to apply impact load or
unbalanced load to the loadcell or peripheral components. It may
cause malfunction of the loadcell.

• Inside of the loadcell cannot receive force. Make sure not to have a
tool hit on the bottom inside the loadcell. It may cause malfunction of
the loadcell.

• When attaching a tool in horizontal orientation, avoid moment load
from being applied to the loadcell.

Wiring

For the controller, only the dedicated controller manufactured by our company can be used.
Use the dedicated cable enclosed in the package when connecting the actuator and the controller.

[Prohibited Items in the Cable Processing]

• Do not pull or bend forcibly the cable so as not to give any extra load or tension to the cable.

• Do not process the cable to extend or shortening by means of cutting out, combination or connecting

with another cable.

• Do not let the cable bend, kink or twist. • Do not let the the cable flex at a single point.

• Do not pull the cable with a strong force. • Do not let the cable receive a turning force at

a single point.

• Do not pinch, drop a heavy object onto • When fixing the cable, provide a moderate
or cut the cable. slack and do not tension it too tight.

• Separate t he I/O line, communication line and power line from each other.
Do not store in the same duct.

Follow the instructions below when using a cable track.

• If there is an indication to the cable for the space factor in a cab le track, refer to the wiring instruction
given by the supplier when storing the cable in the cable track.

• Avoid the cables to get twined or twisted in the cable track, and also to have the cables move freely
and do not tie them up. (Avoid tension being applied when the cables are bent.)
Do not pile up cables. It may cause faster abrasion of the sheaths or cable breakage.

Note:

• When the cable is connected or disconnected, make sure to turn off the power to the controller.
When the cable is connected or disconnected with the controller power turned ON, it might cause a
malfunction of the actuator and result in a serious injury or damage to the machinery.

• When the connector connection is not correct, it would be dangerous because of a malfunction of
the actuator. Make sure to confirm that the connector is connected correctly.
