CAUTION
Risk of electric shock if the protective earth conductor is not connected!
The system into which the P-603 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 starting it up again.
NOTICE
Destruction of the piezo actuator by electric flashovers!
The use of the P-603 in environments that increase the electrical conductivity can lead to the
destruction of the piezo actuator by electric flashovers. Electric flashovers can be caused by
moisture, high humidity, liquids and conductive materials such as metal dust. In addition,
electric flashovers can also occur in certain air pressure ranges due to the increased
conductivity of the air.
Avoid operating the P-603 in environments that can increase the electric conductivity.
Only operate the P-603 within the permissible ambient conditions and classifications
(p. 18).
NOTICE
Destruction of the piezo actuator by continuously high voltage!
The constant application of high voltage to piezo actuators can lead to leakage currents and
flashovers that destroy the ceramic.
If the P-603 is not used, but the controller is to remain switched on to ensure temperature
stability:
Set the piezo voltage to 0 V on the controller.
