Installation Site Power
In the United States, the power supply to the installation site must be 200-240V ac for the MS
and the foreline pump and 100-120V ac for the LC, autosampler, computer, printer and other
modules.
In Europe, the power supply to the site must be 200-240V ac,
The power supply must be stable (free of fluctuations due to slow changes in the average
voltage or to changes resulting from surges, sags, or transients). The voltage must meet
EN/IEC 61000-4-5 and EN/IEC 61000-4-11 standards for voltage stability.
A measured ground to neutral potential of greater than 3V ac or V dc indicates grounding
problems that may need correction. Evaluate any power source suspected of having noise
problems with a recording-type power line monitor before operating the system.
NOTE: If concerned about the quality of the power, install an uninterruptible power supply, or a
power conditioner or both, see Table 12.
