Installing the GC 1
Agilent 7890B Installation 19
Grounding
To protect users, the metal instrument panels and cabinet are
grounded through the three-conductor power line cord in
accordance with International Electrotechnical Commission
(IEC) requirements.
The three-conductor power line cord, when plugged into a
properly grounded receptacle, grounds the instrument and
minimizes shock hazard. A properly grounded receptacle is one
that is connected to a suitable earth ground. Proper receptacle
grounding should be verified.
Make sure the GC is connected to a dedicated receptacle
(outlet).
Line voltage
The GC operates from one of the AC voltage supplies listed in
Table 1, depending on the standard voltage of the country from
which it was ordered.
GCs are designed to work with a specific voltage; make sure
your GC voltage option is appropriate for your laboratory. The
voltage requirements for your GC are printed near the power
cord connector.
Although your GC should arrive ready for operation in your
country, compare its voltage requirements with those listed in
Table 1. If the voltage option you ordered is not suitable for your
installation, contact Agilent Technologies.
Line power cord terminations
The power cord termination is determined by the country
where the GC is ordered.
