Organizational Measures............................................................................................................... 7
2.1 Intended Use
The P-88x/P-08x is intended to be used in an environment which is free of dirt, oil, and
lubricants.
In accordance with its design, the P-88x/P-08x is intended for integration into a mechanical
system and for the following applications:
Positioning of loads
Dynamic positioning
Vibration damping
Force generation
The operator is responsible for a standards-compliant integration of the P-88x/P-08x into the
overall system.
The motion of the P-88x/P-08x takes place on one axis. When mounting the actuator without
applying a preload, pay attention to the maximum tensile stress capacity (p. 51).
For operation of the P-88x/P-08x, suitable electronics that provide the required operating
voltages are required. The electronics are not included in the scope of delivery of the
P-88x/P-08x. We recommend the use of suitable electronics (p. 12) from PI.
2.2 General Safety Instructions
The P-88x/P-08x is built according to state-of-the-art technology and recognized safety
standards. Improper use can result in personal injury and/or damage to the P-88x/P-08x.
Use the P-88x/P-08x for its intended purpose only, and only when it is in perfect
technical condition.
Read the user manual.
Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the P-88x/P-08x.

6 Version: 1.1.0 PZ259E P-88x/P-08x Piezo Actuator
Temperature changes and compressive stress can induce charges in the P-88x/P-08x piezo
actuator. The piezo actuator can remain charged for several hours after disconnecting the
electronics. Touching the live parts on the P-88x/P-08x can result in minor injury from electric
shock.
Do not touch the piezo actuator unless it is discharged (p. 39).
When handling the piezo actuator, wear powder-free nitrile or latex gloves.
Keep the piezo actuator short-circuited (p. 40) when it is not connected to the
electronics.
The system into which the piezo actuator is integrated (e.g., housing or surrounding mechanical
system) must be connected to a protective earth conductor. If the protective earth conductor is
not or not properly connected, touching the system in which the piezo actuator was
incorporated can lead to minor injury from electric shock in the case of a malfunction.
Before startup, connect the overall system to a protective earth conductor in
accordance with the applicable standards.
Do not remove the protective earth conductor during operation.
If the protective earth conductor has to be temporarily removed (e.g., for
modifications), reconnect the overall system to the protective earth conductor before
restarting.
During operation, the piezo actuator carries voltages of up to 120 V (P-88x models) or 100 V
(P-08x models). Touching the piezo actuator can lead to minor injuries from electric shock.
Do not touch the piezo actuator during operation.
Before startup, insulate the piezo actuator electrically from the surrounding mechanics
to prevent direct or indirect contact with live parts. Pay attention to the clearances and
creepage distances required for the operating voltage as well as the standards
applicable to your application.
Mechanical forces can damage the P-88x/P-08x.
Avoid impacts that affect the P-88x/P-08x.
Do not drop the P-88x/P-08x.
Avoid torques and lateral forces on the P-88x/P-08x.
Do not use metal tools during installation.
Do not exceed the maximum permissible stress and load capacities according to the
specifications (p. 47).
Do not exceed the maximum compressive/tensile stress capacity (p. 51).

supplements or technical notes.
If you give the P-88x/P-08x to a third party, include this user manual as well as other
relevant information provided by the manufacturer.
Do the work only if the user manual is complete. Missing information due to an
incomplete user manual can result in minor injury and damage to equipment.
Install and operate the P-88x/P-08x only after you have read and understood this user

3.7 Technical Features
PICMA® piezo actuators
P-88x/P-08x are PICMA® multilayer piezo actuators for static and dynamic applications. PICMA®
actuators have all-ceramic insulation and their performance and lifetime are therefore far
superior to conventional actuators. The ceramic insulation layer protects the monolithic
piezoceramic block against humidity and failure due to increased leakage current. In this way,
an especially high reliability is achieved even under extreme ambient conditions.

NOTICE
Destruction of the piezo actuator due to contamination!
Contamination on the surface of the P-88x/P-08x can result in the destruction of the piezo
actuator by electric flashovers during operation.
When handling the piezo actuator, wear powder-free nitrile or latex gloves.
Prevent the piezo actuator from coming into contact with conductive liquids (e.g., finger
sweat) and conductive materials (e.g., metal dust).
If the piezo actuator has been accidentally contaminated, clean it in accordance with the
instructions in "Cleaning the P-88x/P-08x" (p. 41).
1. Unpack the P-88x/P-08x with care.
2. Compare the contents with the scope of delivery according to the contract and the
delivery note.
3. Inspect the contents for signs of damage. If any parts are damaged or missing, contact
our customer service department (p. 45) immediately.
4. Keep all packaging materials in case the product needs to be returned.
