Important Safety Warnings

There are several important safety notices to always keep in mind when using
the MSD.

Many internal parts of the MSD carry dangerous voltages

If the MSD is connected to a power source, even if the power switch is off,
potentially dangerous voltages exist on:
• The wiring between the MSD power cord and the AC power supply, the AC
With the power switch on, potentially dangerous voltages also exist on:
• All electronics boards in the instrument.
• The internal wires and cables connected to these boards.
• The wires for any heater (oven, detector, inlet, or valve box).
All these parts are shielded by covers. With the covers in place, it should be difficult
WARNING
to accidentally make contact with dangerous voltages. Unless specifically
instructed to, never remove a cover unless the detector, inlet, or oven are turned off.
If the power cord insulation is frayed or worn, the cord must be replaced. Contact
WARNING
your Agilent service representative.

Electrostatic discharge is a threat to MSD electronics

The printed circuit boards in the MSD can be damaged by electrostatic
discharge. Do not touch any of the boards unless it is absolutely necessary. If
you must handle them, wear a grounded wrist strap and take other antistatic
precautions. Wear a grounded wrist strap any time you must remove the MSD
right side cover.
