Table 530-1 Line Voltage Requirements
The fast-heating oven requires at least 200 V. Most countries’ standard voltage
meets this requirement. GCs for use in the USA, Denmark, and Switzerland
will be equipped with a slow-heating oven unless they are ordered with power
option 002, which specifies a fast-heating oven.
Although your GC should arrive ready for operation in your countr y, compare
its voltage requirements with those listed in Table 530-2. If the voltage option
you ordered is not suitable for your installation, contact Agilent Technologies.
USA fast heating oven
The fast heating oven requires 240 V/15A power. Do not use 208 V power.
Lower voltage causes slow oven ramps and prevents proper temperature
control. The power cord supplied with your GC is rated for 250 V/15A, and
is a two pole, three wire cord with grounding (type L6-15R/L6-15P).
