Intended Use
The piezo actuator is a laboratory device as
defined by DIN EN 61010-1. It is intended for
indoor use and use in an environment which is
free of dirt, oil, and lubricants.
In accordance with its design, the piezo
actuator is intended for positioning loads and
generating force in one axis.
The piezo actuator is not intended for applica-
tions in areas where failure would be a consi-
derable risk for people or the environment.
The intended use of the piezo actuator is
only possible when completely mounted and
connected and only in conjunction with suitable
electronics.
The piezo actuator may only be installed,
started and operated, maintained, and cleaned
by authorized and appropriately qualified
personnel.
Actuators with stranded wires:
When installing actuators that were equipped
with stranded wires at the factory, the ope-
rator is responsible for electrical safety and
electromagnetic compatibility according to the
applicable standards.
Electrical Dangers
Temperature changes and compressive stress
can induce charges in piezo actuators. After
disconnection from the electronics, the piezo
actuator can remain charged for several hours.
Touching or short-circuiting the contacts in the
connector or the stranded wires can lead to
minor injuries from electric shock.
X
Do not touch the open ends of the stranded
wires or the contacts in the plug connector.
X
Do not disassemble the piezo actuator.
X
Piezo actuators with stranded wires:
If the piezo actuator is not connected to
the electronics, discharge it and and keep it
short-circuited after discharging.
If a protective earth conductor is not properly
connected, touching the piezo actuator can
result in minor injuries from electric shock.
X
Operate the piezo actuator only with
a properly connected protective earth
conductor.
X
Observe the applicable standards for moun-
ting the protective earth conductor.
Moisture, liquids and electrically conductive
materials (e.g., metal dust) that penetrate the
housing of the piezo actuator can destroy the
piezo actuator.
X
Operate the piezo actuator only under per-
missible ambient conditions (see manual).
X
Do not operate a vacuum-compatible piezo
actuator during evacuation or ventilation.
Excessively high or wrongly connected opera-
ting voltages can cause damage to the piezo
actuator.
X
Use compatible electronics and cables from
PI only.
X
Pay attention to the operating voltage
range of the piezo actuator (see manual).
X
Pay attention to the pin assignment res-
pectively the polarity of the stranded wires
(see manual).
Continuously high voltages can reduce the
lifetime of the piezo actuator.
X
If possible, limit the maximum operating
voltage during continuous operation.
X
Discharge the piezo actuator when it is not
in use.
Mechanical Dangers
Mechanical forces can destroy the piezo actu-
ator.
X
Avoid shocks and drops.
X
Do no exceed the maximum permissible
forces (see manual).
X
Avoid torques, bending, lateral, and pull
forces on the piezo actuator.
X
Do not connect the both ends of the piezo
actuator rigidly.
X
Align the center of load to the piezo actua-
tor's motion axis.
Excessively high operating frequencies can
destroy the piezo actuator.
X
Select the operating frequency according to
the application.
X
Pay attention to the resonant frequency
and dynamic forces (see manual).
