Precautions
⃝ Connect the red lead wire to the positive（＋）terminal of the power supply.
⃝ Carefully avoid electric shock since a high voltage is in use.
⃝ Never apply excessive tension to a lead wire. Do not handle the product by picking up or moving the lead wire.
⃝ Do not disassemble the case of the metal sealed type.
⃝ Machining of the actuator element and replacement of the lead wire are prohibited.
⃝ Do not handle the resin-coated type（AE series）with bare hands. Otherwise, the reliability of the element
would be degraded.
⃝ Do not wash resin-coated type（AE series）by organic solvant.
⃝Avoid excessive physical shock resulting from, for example, dropping. Otherwise, the internal piezoelectric ceramic
element may be damaged.
⃝ If the actuator is exposed to high temperature above 100℃ or if it is used after long storage period（more
than three months）, it should be polarized by using the circuit configuration and conditions shown below.

Protective resistor R1＝1kΩ
Protective resistor R2＝1kΩ
Polarizing conditions: DC voltage application
0V→150±0.2V (to be retained for 10 seconds) →0
⃝ Do not apply voltage exceeding maximum rating voltage, or do not do rapid charging and discharging.
These might lead to degradation of the reliability or mechanical fracture.
⃝ Do not use the actuator in high concentration of highly inflammable gas. Otherwise, ignition may occur.
⃝ Use the actuator so as not to cause bending, twisting or tension. Furthermore, align the center axis of displacement
of the actuator with the center axis of the mechanical load.
⃝ Drive the actuator so that the rising speed is more than three times as much as the resonance period in
order to prevent the device from damaging by ringing.
⃝ Store the resin-coated type（AE series）preferably in a dry atmosphere（desirably below 40% RH）at ordinary
temperatures（－5 to ＋40˚C）. Avoid condensation on the product surface.
⃝ Store actuators where there is no vibration.
⃝These products must be handled properly as industrial waste. When disposing, please contact your local waste
disposal service.
⃝ Piezo actuator is industrial wastes, make sure disposal method under the laws.
