10 7820A GC Site Preparation Guide
1 7820A GC Site Preparation
Power Consumption
Table 3 lists site power requirements.
• The number and type of electrical outlets depend on the size
and complexity of the system.
• Power consumption and requirements depend on the
country to which the unit ships. Find the instrument type
and your line voltage to find your instrument’s power
requirements.
• The electrical outlet for the unit should have a dedicated
ground. Voltage between ground and neutral should be less
than 2.5 VAC.
• The voltage requirements for your instrument are printed
near the power cord attachment.
Although your GC should arrive ready for operation in your
country, compare its voltage requirements with those listed in
Table 3. If the voltage option you ordered is not suitable for your
installation, contact Agilent Technologies.

Do not use extension cords with Agilent instruments. Extension cords normally are
not rated to carry enough power and can be a safety hazard.
