12 Installation, Operation, and Maintenance
Important Safety Warnings
There are several important safety notices that you should always keep in
mind when using the Automatic Liquid Sampler.
Many internal parts of the instrument carry dangerous voltages
If the instrument is connected to a power source, even if the power switch is
off, potentially dangerous voltages exist on:
• The wiring between the instrument power cord and the AC power supply
• The AC power supply itself
• The wiring from the AC power supply to the power switch
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
Electrostatic discharge is a threat to instrument electronics
The printed circuit (PC) boards in the instrument 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 electronics cover.
WARNING
All these parts are shielded by covers. With the covers in place, it should be difficult
to accidentally make contact with dangerous voltages. Unless specifically
instructed to, never remove a cover.
WARNING
If the power cord insulation is frayed or worn, the cord must be replaced. Contact
your Agilent service representative.
