Electrostatic discharge is a threat to GC electronics

Before moving on, there are several important safety notices
that you should always keep in mind when using the 6820 GC.
If the GC is connected to a power source, even if the power
switch is off, potentially dangerous voltages exist on:
• The wiring between the GC power cord and the AC power
supply, the AC power supply itself, and 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.
• 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 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 your Agilent service representative.
The printed circuit (PC) boards in the GC 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 GC
right side cover.
