Chapter 2 Safety Warning Piezo actuators are driven by high voltages. Voltages up to 150V may be present at the connector. This is hazardous and can cause serious injury. Appropriate care should be taken when using this device. Persons using the device must understand the hazards associated with using high voltages and the steps necessary to avoid risk of electrical shock.
APF503, APF705 and APF710 Amplified Flexure Piezo Actuators Chapter 3 Installation 3.1 Storage Precautions Warning Piezos can store and release large amounts of energy and should be handled with caution. To prevent charge build up, piezos must be stored with the high voltage wires (red and white) joined together (short circuit).

Any residual charge remaining in the piezo stack should be discharged. For a complete tutorial on driving the actuator using the Thorlabs range of controllers, see the handbook for the appropriate controller. Basic steps in controlling the actuator using a Thorlabs controller are as follows: 1) Fit the actuator to the relevent stage or mount.
