PZ266E
P-88x.x5 Piezo Actuator
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.
