General Notes on Starting
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 U-651 in the case of malfunction or failure of the system. If there are touch
voltages, touching the U-651 can result in minor injuries from electric shock.
Connect the U-651 to a protective earth conductor (p. 17) 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 U-651 to the protective earth conductor before restarting.
NOTICE
Destruction of the piezo motor due to electric flashovers!
Using the U-651 in environments that increase the electrical conductivity could lead to the
destruction of the piezo motor by electric flashovers. Electric flashovers can be caused by
moisture, high humidity, liquids, and conductive materials (e.g., metal dust). In addition,
electric flashovers are also possible as a result of increased conductivity in certain air pressure
ranges.
Avoid operating the U-651 in environments that can increase the electrical conductivity.
Operate the U-651 only under permissible ambient conditions and classifications (p. 37).
When using in a vacuum under 0.1 hPa:
Do
not
operate the U-651 while evacuating or ventilating.
