General Notes on Installation

CAUTION

Dangerous voltage and residual charge in piezo actuators!

Temperature changes and compressive stresses can induce charges in the PL0xx/PDxxx piezo

actuator. After disconnection from the electronics, the piezo actuator can remain charged for

several hours. Touching the live parts of the PL0xx/PDxxx can result in minor injury from

electric shock.



Do

not

touch the piezo actuator unless it is discharged (p. 40).



When handling the piezo actuator, wear powder-free nitrile or latex gloves.



Keep the piezo actuator short-circuited (p. 41) when it is not connected to the electronics.



Do

not

disassemble the piezo actuator.
