Safety Instructions - piezosystemjena NV40/3 Bedienungsanleitung


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.


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.

Do not spill any liquids into the cabinet or use the units near water.
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).

Work with the units only in a clean and dry environment! Only specially prepared units (e.g.
actuators) can work under other conditions!

Please use only original parts from piezosystem jena.

piezosystem jena does not give any warranty for damages or malfunction caused by
additional parts not supplied by piezosystem jena. Additional cables or connectors will
change the calibration and other specified data. This can change the specified properties of
the units and cause them to malfunction.

Do not place the units on a sloping or unstable cart, stand or table as they may fall or not
work accurately.

Piezo elements are sensitive systems capable of the highest positioning accuracy. They will
demonstrate their excellent properties only if they are handled correctly! Please mount
them properly only at the special mounting points.
Immediately unplug your unit from the wall outlet and refer servicing to qualified service
personnel under the following conditions:
