Mounting the P-5x7/P-5x8
NOTICE
Warping the P-5x7/P-5x8 when mounting onto uneven surfaces!
The P-5x7/P-5x8 could warp if mounted on an uneven surface. Warping reduces the accuracy.
Mount the P-5x7/P-5x8 onto a flat surface. The recommended flatness of the surface is
≤20
µm.
For applications with large temperature fluctuations:
Mount the P-5x7/P-5x8 only onto surfaces that have the same or similar thermal expansion
properties as the P-5x7/P-5x8.
NOTICE
Tensile stress on piezo actuator due to mounting in wrong orientation!
The P-5x7/P-5x8 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-5x7/P-5x8 in a different orientation to that intended (e.g.,
vertically or upside down), contact our customer service department (p. 35).

Requirements
You have read and understood the general notes on installing (p. 17).
You have provided a suitable surface for fixing the P-5x7/P-5x8:
−
The surface has four threaded holes for M6 screws. Refer to "Dimensions" (p. 42)
for the position and depth required for the holes.
−
The surface flatness is ≤2
0 µm.
−
For applications with large temperature fluctuations: The surface should have the
same thermal expansion properties as the P-5x7/P-5x8 (e.g., surface made of
aluminum).
