Intended Use
The piezo actuator is a laboratory device as
dened by DIN EN 61010-1. It is intended for
indoor use and use in an environment that is
free of dirt, oil, and lubricants.
In accordance with its design, the piezo actua-
tor is intended for integraon into a mechanical
system for the posioning of loads, dynamic
posioning, vibraon absorpon, and force
generaon. The operator is responsible for
a standards-compliant integraon into the
overall system.
The piezo actuator is not intended for applica-
ons in areas where failure would be a consi-
derable risk for people or the environment.
The moon of the piezo actuator is along one
axis.
The intended use of the piezo actuator is
only possible when completely mounted and
connected. The piezo actuator must be ope-
rated with suitable electronics (refer to user
manual). The electronics are not included in the
scope of delivery of the piezo actuator.
The piezo actuator may not be used for
purposes other than those stated in the user
manual. The piezo actuator may only be used
in compliance with the technical specicaons
and instrucons in the user manual.
Electrical Dangers
Temperature changes and compressive stress
can induce charges in piezo actuators. Aer
disconnecng from the electronics, the piezo
actuator can remain charged for several hours.
Touching live parts can result in minor injury
from electric shock.
XDo not disassemble the piezoelectric
actuator.
XDo not touch any live parts (depending on
the model, e.g., open piezo actuator, open
ends of stranded wires, or contacts in the
plug connector).
XRemove the shorng clamp or shorng plug
that is in the scope of delivery only if neces-
sary for installaon or operaon purposes.
XIf you disconnect the piezo actuator from
the electronics, discharge it and keep it
short-circuited aer discharging.
XDo not disconnect the piezo actuator from
the electronics during operaon.
If the protecve earth conductor is missing or
not properly connected, touching the piezo
actuator can result in minor injuries from
electric shock in the case of a malfuncon.
XOperate the piezo actuator only with a
properly connected protecve earth
conductor.
XObserve the applicable standards for moun-
ng the protecve earth conductor.
Electric ashovers can be caused by moisture,
liquids, and conducve materials (e.g., metal
dust) and can destroy the piezo actuator during
operaon. In addion, electric ashovers can
also occur in certain air pressure ranges due to
the increased conducvity of the air.
XAvoid operang the piezo actuator in
environments that can increase the electric
conducvity.
XOperate the piezo actuator only under
permissible ambient condions (refer to
user manual).
Safety Informaon

MOTION | POSITIONING
PZ302EK 1.0.0 11/2019. 0.5
Models with an open housing:
XWhen handling the piezo actuator, wear
powder-free nitrile or latex gloves.
XPrevent the piezo actuator from coming
into contact with conducve liquids (e.g.,
nger sweat) and conducve materials
(e.g., metal dust).
Excessively high or wrongly connected opera-
ng voltages can cause damage to the piezo
actuator.
XUse compable electronics and cables from
PI only.
XPay aenon to the operang voltage
range of the piezo actuator (refer to user
manual).
XPay aenon to the pin assignment res-
pecvely the polarity of the stranded wires
(refer to user manual).
The constant applicaon of high voltage to
piezo actuators can lead to leakage currents
and ashovers that will destroy the ceramic.
XIf possible, limit the maximum operang
voltage during connuous operaon.
XDischarge the piezo actuator when it is not
in use.
Mechanical Dangers
Mechanical forces can destroy the piezo actu-
ator.
XAvoid shocks and drops.
The piezo actuator can be damaged by pull
forces acng on the stranded wires or the
connecng cable.
XAvoid pull forces on the stranded wires or
on the connecng cable.
High torques when ghtening the load and high
loads can overload the movable part of the
piezo actuator. Mechanical overload can cause
damage to the piezo actuator and the exures
and can also lead to loss of accuracy.
XPay aenon to the torque range specied
for the screws used during installaon
(refer to user manual).
XDo not exceed the maximum permissible
torque (refer to user manual) on the mo-
vable part of the piezo actuator.
XDo not exceed the maximum permissible
load capacies according to the specica-
ons (refer to user manual).
Excessively high operang frequencies can
destroy the piezo actuator.
XSelect the operang frequency according to
the applicaon.
XPay aenon to the resonant frequency
and dynamic forces (refer to user manual).
Excessively steep edges in the control signal or
excessively fast discharging can trigger a strong
mechanical impulse and damage the piezo
actuator.
XAvoid steep edges in the control signal.
XDischarge the piezo actuator before
short-circuing.
XIf the connecng cable is accidentally
pulled out during operaon, switch o the
electronics before you reconnect.
Uncontrolled oscillaon can damage the piezo
actuator or your applicaon. Oscillaon is indi-
cated by a humming noise and can be caused by
the following:
▪▪A change in the load and/or dynamics
requires the servo control or operang
parameters to be adjusted.
▪▪The piezo actuator is operated near to its
resonant frequency.
XIf oscillaon occurs, switch o the servo
mode of the electronics or stop the piezo
actuator immediately.
XCheck the servo control sengs respec-
vely the sengs for the operang para-
meters (refer to user manual).
Models with open housing:
Touching live parts during operaon can result
in minor injury from electric shock.
XDo not touch the piezo actuator during
operaon.
XInsulate the piezo actuator electrically
from the surrounding mechanics before
startup to prevent direct or indirect contact
with live parts. Pay aenon to both the
clearance and creepage distances required
for the operang voltage and the standards
applicable to your applicaon.

Thermal Dangers
For models P-603 and P-604 only:
The surface of the piezo actuator and its
surroundings can heat up during operaon.
Touching the piezo actuator and its surrounding
parts can result in minor injuries from burning.
XMake sure that the hot piezo actuator and
the surrounding parts cannot be touched.
All models:
The heat produced during operaon of the
piezo actuator can aect your applicaon.
XInstall the piezo actuator so that the appli-
caon is not impaired by dissipang heat.
Connecng the Piezo Actuator to the
Protecve Earth Conductor
The piezo actuator does not have a separate
protecve earth connector. For this reason, the
risk of electric shock must be prevented in one
of the following ways:
▪▪Installing the piezo actuator on an electri-
cally conducve surface connected to a
protecve earth conductor
▪▪Connecng the piezo actuator to a pro-
tecve earth conductor via its mounng
interfaces (holes)
▪▪Electrical insulaon of the piezo actuator
according to protecon class II
Connecng the piezo actuator to the protec
ve earth conductor
XPay aenon to the applicable standards
for connecng the protecve earth con-
ductor.
XUse electrically conducve mounng mate-
rial (e.g., screws or glue)

ng type of your model.
