2.1 Intended Use
The P-88x.x5 is intended for use in an environment where spray water or oil is possible or
where high air humidity prevails.
In accordance with its design, the P-88x.x5 is intended for integration into a mechanical system
and for the following applications:
Positioning of loads
Vibration damping
Force generation
The following applications are only permitted after consultation with the customer service
department (p. 37):
Dynamic positioning
Complete immersion into a liquid
The operator is responsible for standards-compliant integration of the P-88x.x5 into the overall
system.
The motion of the P-88x.x5 takes place in one axis. When mounting without preload, avoid
tensile stress (p. 41).
For operation of the P-88x.x5, suitable electronics that provide the required operating voltages
are required. The electronics are not included in the scope of delivery of the P-88x.x5. We
recommend the use of suitable electronics (p. 11) from PI.
2.2 General Safety Instructions
The P-88x.x5 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.x5.
Use the P-88x.x5 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.x5.

Temperature changes and compressive stress can induce charges in the P-88x.x5 piezo
actuator. The piezo actuator can remain charged for several hours after disconnecting the
electronics. Touching the live parts on the P-88x.x5 can result in minor injury from electric
shock.
Touch the stranded wires only when the piezo actuator is discharged (p. 30).
Keep the piezo actuator short-circuited (p. 31) when it is not connected to the
electronics.
Do not disassemble the piezo actuator.
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.
Mechanical forces can damage the P-88x.x5.
Avoid impacts that affect the P-88x.x5.
Do not drop the P-88x.x5.
Avoid torques and lateral forces on the P-88x.x5.
Do not use metal tools during installation.
Do not exceed the maximum permissible stress and load capacities according to the
specifications (p. 39).
Do not exceed the maximum compressive/tensile stress capacity (p. 41).
If the piezo actuator is to be used in a vacuum, attention must be paid to the corresponding
cleanliness. At PI, all parts are cleaned before assembly. During assembly and calibration,
powder-free gloves are worn. Afterwards, the piezo actuator is wiped clean once again and
then shrink-wrapped in vacuum-compatible film.
When handling the piezo actuator, wear powder-free nitrile or latex gloves.
If necessary, wipe the piezo actuator clean after unpacking.

3.7 Technical Features
PICMA® piezo actuators
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.
Encapsulated PICMA® stack piezo actuators
Encapsulated PICMA® stack actuators are surrounded by inert gas and have a stainless steel
housing. They can also be used when the application environment is characterized by oil, spray
water or continuously high humidity.

5.1 General Notes on Installing
CAUTION
Dangerous voltage and residual charge in piezo actuators!
Temperature changes and compressive stress can induce charges in the P-88x.x5 piezo
actuator. The piezo actuator can remain charged for several hours after disconnecting the
electronics. Touching the live parts on the P-88x.x5 can result in minor injury from electric
shock.
Touch the stranded wires only when the piezo actuator is discharged (p. 30).
Keep the piezo actuator short-circuited (p. 31) when it is not connected to the electronics.
Do not disassemble the piezo actuator.
NOTICE
Destruction of the piezo actuator due to rapid discharging!
If the piezo actuator is not connected to the electronics, it must be short-circuited in order to
prevent the piezo actuator from becoming charged during temperature changes and
compressive stress. Unsuitable short-circuiting leads to an abrupt contraction of the piezo
actuator due to excessively fast discharging. Abrupt contraction can destroy the piezo actuator.
As soon as you have removed the piezo actuator from the conductive original packaging,
twist the stranded wires together.
Only disconnect the short-circuit connection of the piezo actuator if this is necessary for
installation or operation.
If the piezo actuator is not short-circuited:
−Ensure adequate protection against touching live parts.
−Discharge the piezo actuator in a suitable way before short-circuiting again (p. 30).

16 Version: 1.1.0 PZ266E P-88x.x5 Piezo Actuator
NOTICE
Short-circuiting due to complete immersion in a liquid!
Complete immersion of the P-88x.x5 into a liquid can lead to short-circuiting at the stranded
wires. A short-circuit can destroy the P-88x.x5 as well as the electronics connected.
Avoid immersing the stranded wires into liquids. If your application requires complete
immersion of the P-88x.x5 into a liquid, contact our customer service department (p. 37).
NOTICE
Damage to the piezo actuator due to excessive preloading!
Excessive preloading can mechanically depolarize the piezo actuator. Depolarization damages
the piezo actuator.
Only apply preloads that are just as high as necessary.
Do
not
exceed the maximum preload (p. 41).
NOTICE
Destruction of the piezo actuator due to mechanical overload!
Torques, lateral forces, and excessive loads can destroy the piezo actuator.
Do not exceed the maximum compressive/tensile stress capacity (p. 41).
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 to the piezo actuator due to sideways mounting!
Sideways mounting of the housing leads to deformation of the metal bellows of the piezo
actuator and restricts its motion. The piezo actuator can be damaged when mounting the
housing sideways.
Do not mount the housing of the piezo actuator sideways.
NOTICE
Damage due to tensile stress on the stranded wires of the piezo actuator!
Impermissible forces on the stranded wires can damage the piezo actuator.
Avoid tensile stress on the stranded wires of the piezo actuator.
