General Notes on Start-Up and Operation
CAUTION
Dangerous voltage in piezo actuators during operation!
During operation, the piezo actuator carries voltages of up to 100 V. Touching the piezo
actuator can lead to minor injuries from electric shock.
Do
not
touch the piezo actuator during operation.
Before start-up, insulate the piezo actuator electrically from the surrounding mechanical
system to prevent direct or indirect contact with live parts. Observe the clearances and
creepage distances required for the operating voltage, and observe the standards
applicable to your application.
CAUTION
Risk of electric shock if the protective earth conductor is not connected!
The system into which the piezo actuator 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 start-up, 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.
