9.2.2 Installation of RCA2-SA3C, SA4C, SA5C, SA6C, SA3R, SA4R, SA5R and SA6R
The surface to mount the main unit should be a machined surface or a plane that possesses an equivalent
accuracy and the flatness should be within 0.05mm. Also, the platform should have a structure stiff enough
to install the unit so it would not generate vibration or other abnormality.
This actuator has the screw holes for mounting so it can be fixed from the rear side.
(Note that tap hole size depends on model. Please see diagrams below and 2, "External Dimensions.")
The actuator also contains reamed holes for use with positioning pins.
