Introduction to the Chip Cube 2
Introduction
To disable the CCD camera and illumination system, disconnect the external
power supply from line power.
For power ratings and line voltage range see "Power Considerations" on
page 32.

Safety Features

Different safety features protect the user from hazards when using the Agilent
G4240A HPLC-Chip MS Interface.
Interlock Switches
The Chip Cube is equipped with two interlock switches which immediately
stop any mechanical movement and turn off high voltage sources when
triggered.
The MS interlock checks whether the Chip Cube is attached to the Chip Cube
Interface Assembly (spray chamber). If the interface is not recognized, the
Chip Cube will not move any parts and will activate the Not Ready line of the
APG connector.
The front door interlock switch is triggered when the Chip Cube front door is
opened. As with the MS interlock, all mechanical movements are stopped and
a Not Ready condition is set.
Voltages in Customer Accessible Areas
User accessible electronic boards inside the Chip Cube carry no voltages
higher than 36 V DC.
Leak Handling
Due to the extremely small flow rates of typically 4 µL/min or less, no leak
drain is necessary.
Spray Chamber
The spray chamber is located inside the Chip Cube Interface Assembly. With
the waste hose connected to an exhaust vent with slightly negative pressure,
no harmful solvents or sample material can escape into the laboratory
environment.
