· Piezoelectric actuators are able to work under high compressive forces. Only actuators with a pre-load can
be used under tensile loads (these tensile forces must be less then the pre-load, given in the data sheet).
· Please note that the acceleration of the ceramic material (e.g., caused by fall down, discharging or high
dynamic application) will occur.
· After excitation of the actuators by a voltage in the upper control range, the ceramic will move and generate
an opposite high voltage after disconnection.
· Heating of the ceramic material will occur during dynamic operation and is caused by structure conditional
loss processes. This may cause failure if the temperature exceeds specified values cited below.
· With increasing temperature, up to the Curie temperature (usual values approx. 140°C - 250°C), the
piezoelectric effect disappears.
· Piezoelectric actuators such as stacks or other devices work electrically as a capacitor. These elements are
able to store electrical energy over a long period of time (up to some days) and the stored energy may be
dangerous.
· If the actuator remains connected to the drive electronics, it will be unloaded within a second after shutdown
and quickly reaches harmless voltage values.
· Piezo-actuators can generate voltages by warming or cooling only (caused by the longitudinal change). The
discharge potential should not be ignored due to the inner capacitance. This effect is insignificantly at usual
room temperature.
· Piezo-actuators from piezosystem jena are adjusted and glued. Any opening of the unit will cause
misalignment or possible malfunction and the guarantee will be lost.
· Please use only original parts from piezosystem jena.
· Please contact piezosystem jena or your local representative, if there are any problems with your actuator
or power supply.
Caution!
Shock forces may damage the built-in ceramic elements. Please avoid such forces, and handle the units with
care, otherwise the guarantee will be lost.

2.6 safety instructions

Icons
RISK OF ELECTRIC SHOCK! Indicates that a risk of electric shock is present and the
associated warning should be observed.
CAUTION! REFER TO OPERATOR´S MANUAL – Refer to your operator's manual for additional
information, such as important operating and maintenance instructions.
RISK OF ELECTRIC SHOCK!
· Do not open the units! There are no user serviceable parts inside and opening or removing covers may
expose you to dangerous shock hazards or other risks. Refer all servicing to qualified service personnel.
CAUTION!
· Allow adequate ventilation around the units so that heat can properly dissipate. Do not block ventilated
openings or place the units near a radiator, oven or other heat sources. Do not put anything on top of the
units except those that are designed for that purpose (e.g. actuators).
· Do not spill any liquids into the cabinet or use the units near water.
· Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which
can be harmful or fatal or may cause electric shock, fire or equipment failure.
· Do not place any heavy objects on any cables (e.g. power cords, sensor cables, actuator cables, optical
cables). Damage may cause malfunction or shock or fire!
· Do not place the units on a sloping or unstable cart, stand or table as they may fall or not work accurately.
· Work with the units only in a clean and dry environment! Only specially prepared units (e.g. actuators) can
