5.3 Mounting the P­611
NOTICE
Warping the P­611 when mounting onto uneven surfaces!
The P-611 could warp if mounted on an uneven surface. Warping reduces the accuracy.

Mount the P-611 onto a flat surface. The recommended flatnes s of the surface is ≤20 µm.

For applications with large temperature changes:
Mount the P-611 only onto surfaces that have the same or similar thermal expansion
properties as the P-611.
NOTICE
Tensile stress on piezo actuator due to mounting in wrong orientation!
The P-611 is intended for mounting in horizontal orientation (standing on a surface, not
suspended). Mounting in other orientations can cause tensile stress that reduces the preload
and destroys the piezo actuator.

If you want to mount the P-611 in a different orientation to that intended (e.g., vertically
or upside down), contact our customer service department (p. 33).
The following figures serve as examples and can differ from your positioner model.
