6.1 General Notes on Starting and Operating
CAUTION
Risk of electric shock if the protective earth conductor is not connected!
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-73x in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-73x can result in minor injuries from electric shock.
 Connect the P-73x to a protective earth conductor (p. 20) before starting.
 Do not remove the protective earth conductor during operation.
 If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-73x to the protective earth conductor before restarting.
NOTICE
Destruction of the piezo actuator due to electric flashovers!
Using the P-73x in environments that increase the electrical conductivity can lead to the
destruction of the piezo actuator by electric flashovers. Electric flashovers can be caused by
moisture, high humidity, liquids, and conductive materials (e.g., metal dust). In addition,
electric flashovers can also occur in certain air pressure ranges due to the increased
conductivity of the air.
 Avoid operating the P-73x in environments that can increase the electric conductivity.
 Operate the P-73x only within the permissible ambient conditions and classifications
(p. 42).
NOTICE
Decreased lifetime due to permanently high voltage!
Applying a continuous high static voltage to piezo actuators reduces the lifetime of the piezo
ceramic.
 When the P-73x is not used but the electronics remain switched on to ensure temperature
stability, discharge the P-73x (p. 29).
