Mounting tapped holes are provided on the back of the base. Use these tapped holes for mounting the
actuator. The effective depth of the screws for mounting the base is as shown below. Exercise due caution
that the tip of the bolt does not stick out.
If an inappropriate bolt is used, the tapped holes may be damaged and/or the mounting strength of the
actuator may become insufficient, causing the degradation of precision and/or unexpected accidents.
Additionally, the reamed holes for the positioning pins are provided on the back of the base.
