5.3 Mounting the P­54x
NOTICE
Distorting the P­54x when mounted on uneven surfaces!
Fixing the P-54x onto an uneven surface can distort the P-54x. Distortion reduces the accuracy.

Fix the P­54x onto an even surface. The recommended flatness of the surface is ≤20 µm.

For applications with large temperature fluctuations:
Only fix the P-54x onto surfaces that have the same or similar thermal expansion
properties as the P-54x (e.g., surfaces made of aluminum).
NOTICE
Tensile stress when mounted vertically!
When the P-54x is mounted vertically, certain alignments can cause tensile stress that reduces
the preload and destroys the piezo actuator.

If you want to mount the P-54x vertically, contact our customer service department (p. 33).

Requirements

You have read and understood the general notes on installation (p. 17).

You have provided a suitable surface for fixing the P-54x:
− The surface has four suitable threaded holes for the mounting screws (refer to
"Dimensions" (p. 40)).
− The surface flatness is ≤20 μ m.
