2 Safety
Piezo motors are driven by piezo actuators. Piezo actuators can remain electrically charged for
several hours after disconnecting the electronics. Temperature changes can also induce charges
in piezo actuators. Touching the contacts in the connection sockets of the M-687.UN (or in the
connectors of the connected cables) could lead to minor injuries from electric shock. In
addition, the piezo actuators could be destroyed by an abrupt contraction.
 Do not open the M-687.UN.
 Do not touch the contacts in the connection sockets of the M-687.UN.
 If an adapter or connecting cable is connected to the M-687.UN, do not touch the
contacts in the connector.
 Do not pull the connectors out of the electronics during operation. If possible, use
screws to secure the connectors against being pulled out of the electronics.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the M-687.UN in the case of malfunction or failure of the system. If there are touch
voltages, touching the M-687.UN can result in minor injuries from electric shock.
 Connect the M-687.UN to a protective earth conductor (p. 16) 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 M-687.UN to the protective earth conductor before
restarting.
Mechanical forces can damage or misalign the M-687.UN.
 Avoid impacts that affect the M-687.UN.
 Do not drop the M-687.UN.
 Do not exceed the maximum permissible stress and load capacities (p. 37).
