[*] Not for external use
The actuator is connected to this plug. The actuator voltage goes to the piezo, the position signal from
the measurement system goes to the DSP, and the integrated actuator information is stored on an ID-
chip which goes to the main controller. It is important that the locking screws are screwed into the front
panel. The dangerous voltages will be switched on only after connecting the actuator. When
disconnecting the actuator, the dangerous voltages will be switched off by a safety relay.
