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).
