5 Installation
P­54x Nanopositioner PZ244E Version: 1.2.0 21
−
For applications with large temperature fluctuations: The surface should have the
same or similar thermal expansion properties as the P-54x (e.g., aluminum surface).
Tools and accessories

Screws of suitable size and length (refer to "Dimensions" (p. 40))

Suitable screwdriver
Mounting the P­54x
1. Align the P-54x so that the mounting holes in the base body (see figure) are in line with
the corresponding holes in the surface.
2. Fix the P-54x using the screws:
a)
Insert a screw into each hole.
b) Tighten the screws. Pay attention to the specified torque range (p. 42).
3. Check that the P-54x is sitting firmly on the surface.
5.4 Fixing the Load
NOTICE
Mechanical overload of the platform!
High torques during fastening of the load as well as high loads can overload the platform of the
P-54x. Mechanical overload can cause damage to the piezo actuators, sensors, and flexures of
the P-54x and lead to loss of accuracy.

Avoid torques > 1 Nm on the platform.

Do not exceed the maximum permissible loads according to the specifications (p. 35).

Hold the load and adhere to the specified torque range (p. 42) when tightening (or
loosening) the screws.
NOTICE
Distorting the P­54x when fixing loads with an uneven contact surface!
Fixing loads with an uneven contact surface could distort the P-54x. Distortion reduces the
accuracy.

Fix loads to the P-54x only when the surface contacting the positioner's platform has a
flatness of at least 20 μ m.

For applications with large temperature fluctuations:
Mount loads onto the P-54x only if they have the same or similar thermal expansion
properties as the P-54x (e.g., loads made of aluminum).
