Safety Precautions
Electrical dangers
CAUTION
Dangerous voltage and residual charge on piezo actuators!
The P-736.ZRx is driven by piezo actuators. Temperature changes and compressive stresses can
induce charges in piezo actuators. After being disconnected from the electronics, piezo
actuators can also stay charged for several hours. Touching or short-circuiting the contacts in
the connector of the P-736.ZRx can lead to minor injuries from electric shock. In addition, the
piezo actuators can be destroyed by an abrupt contraction.
Do
not
open the P-736.ZRx.
Discharge the piezo actuators before installation:
Connect the P-736.ZRx to the switched-off PI controller.
Do
not
pull the connector out of the controller during operation.
For piezo scanners with D-sub connector:
Touching the contacts in the connector can lead to an electric shock (max. 130 V DC) and minor
injuries.
Do
not
touch the contacts in the connector.
Secure the connector of the piezo scanner with screws against being pulled out of the
controller.
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 and there is a risk of electric shock. In the event of malfunction or failure of the system,
touching the P-736.ZRx can result in minor injuries.
Connect the P-736.ZRx to a protective earth conductor (p. 11) before startup.
Do
not
remove the protective earth conductor during operation.
If the protective earth conductor has to be temporarily removed (e.g., for modifications),
reconnect the P-736.ZRx to the protective earth conductor before starting it up again.
NOTICE
Destruction of the piezo actuators by electric flashovers!
The use of the P-736.ZRx in environments that increase the electrical conductivity can lead to
the destruction of the piezo actuators by electric flashovers. Electric flashovers can be caused
by moisture, high humidity, liquids and conductive materials such as 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-736.ZRx in environments that can increase the electric conductivity.
Only operate the P-736.ZRx within the permissible ambient conditions and classifications
(p. 21).
