NOTICE
Destruction of the piezo actuator due to mechanical overload!
Torques and lateral forces can destroy the piezo actuator.
Avoid torques and lateral forces on the piezo actuator.
Make sure that the center of load of the moving system is on the motion axis of the piezo
actuator.
Avoid an uneven load distribution by using suitable structures or guide elements (e.g., ball
tips or flexure guides).
Establish contact over as large an area as possible on the end surfaces of the piezo
actuator, and select opposing surfaces with a flatness of only a few micrometers. Minor
unevenness can be compensated by full-surface gluing, for example.
NOTICE
Damage due to tensile stress on the stranded wires of the piezo actuators!
Impermissible forces on the stranded wires (if applicable) can damage the piezo actuator.
Avoid tensile stress on the stranded wires of the piezo actuator.
NOTICE
Damage due to scratches on the surface of the piezo actuator!
The surface of the piezo actuator is scratch-sensitive. Scratches on the surface can cause
damage to the piezo actuator.
Do not use metal tools to install the piezo actuator.
Install the piezo actuator so that the ceramic insulation and the end surfaces of the piezo
actuator are not scratched during installation and operation.
NOTICE
Heating up of the PL0xx/PDxxx during operation!
The heat produced during operation of the PL0xx/PDxxx can affect your application.
Install the PL0xx/PDxxx so that your application is not affected by the dissipating heat.
INFORMATION
Ground loops can occur when the piezo actuator is installed in a housing that is grounded via
the shield of the connecting cable of the piezo actuator as well as a separate protective earth
conductor.
If a ground loop occurs, contact our customer service department (p. 47).
