  • Page 9: Safety Precautions

    E-665s are amplifiers generating voltages up to 130 V for driving LVPZTs. The output power may cause serious injury. Only connect original PI parts to the »PZT« socket of the E-665. All work done with and on the devices described here requires adequate knowledge and training in handling High Voltages.
