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.
•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 within 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 thetable will increase.
•When mounting the actuator leave a gap of 40 mm or more to allow
for bending of the actuator cable.
•When mounting the actuator or workpiece, 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
dropping of the work piece.
