System Overview

Modules

The 7683 Automatic Liquid Sampler system, shown in Figure 1, can include:

• One G2612A ALS interface board (required on 6890 GC, not used on 6850 GC)

• One or two G2613A injector module(s)

• One G2614A 100 vial tray (optional, 6890 GC only)

• One G1926A Bar Code Reader (optional, 6890 GC only)–requires INET
integrator or ChemStation

System Overview

Safety

Safety

Before servicing the various components of the GC, observe the following safety
precautions.

Caution

Follow the precautions below when servicing the instrument to avoid data loss
or damage to the instrument.

Printed circuit boards

When storing printed circuit boards (PCBs), always place them in static control
envelopes or enclosures.

Always make sure you are properly grounded (e.g., wearing an ESD strap) before
handling electrostatic sensitive components such as printed circuit boards.

Voltage carrying components

When disconnecting plugs, pull on the plug, not its wires. Pulling on the wires
may cause breakage.

Warnings

The following are potential hazards that can cause personal injury.

Heated components

Parts of the injector may become hot. Turn off the GC oven and inlet/detector
heated zones and allow them sufficient time to cool before servicing those areas.
If you must perform service on components that have not fully cooled, wear
protective gloves.

Voltage carrying components

Whenever possible, disconnect the G2613A Injector and G2614A Tray from the
GC before working on them.

MAR 2000 3

System Overview

Safety

Whenever possible, disconnect the GC from its power source before working on
or near voltage carrying components of the GC.

The following components carry voltage when the GC is plugged in even if the
power switch is off:

• The AC power cord

• The AC power supply

When the power to the GC is turned on, potentially dangerous voltages exist on
these additional components:

• The power transformer

• All electronics boards

• All internal wires and cables connected to these boards

• The injector, tray, and bar code reader cables that connect to the GC

• All internal wires, cables, and boards in the injector, tray, and bar code
reader
