General Notes on Installing
CAUTION
Dangerous voltage and residual charge in piezo actuators!
Temperature changes and compressive stress can induce charges in the P-88x.x5 piezo
actuator. The piezo actuator can remain charged for several hours after disconnecting the
electronics. Touching the live parts on the P-88x.x5 can result in minor injury from electric
shock.
Touch the stranded wires only when the piezo actuator is discharged (p. 30).
Keep the piezo actuator short-circuited (p. 31) when it is not connected to the electronics.
Do
not
disassemble the piezo actuator.
NOTICE
Destruction of the piezo actuator due to rapid discharging!
If the piezo actuator is not connected to the electronics, it must be short-circuited in order to
prevent the piezo actuator from becoming charged during temperature changes and
compressive stress. Unsuitable short-circuiting leads to an abrupt contraction of the piezo
actuator due to excessively fast discharging. Abrupt contraction can destroy the piezo actuator.
As soon as you have removed the piezo actuator from the conductive original packaging,
twist the stranded wires together.
Only disconnect the short-circuit connection of the piezo actuator if this is necessary for
installation or operation.
If the piezo actuator is not short-circuited:
−
Ensure adequate protection against touching live parts.
−
Discharge the piezo actuator in a suitable way before short-circuiting again (p. 30).
