1Installing the Vacuum Degasser

Site Requirements

A suitable environment is important to ensure optimum performance of the

vacuum degasser.

Power Considerations

The vacuum degasser power supply has wide-ranging capability (see Table 1

on page 11). It accepts any line voltage in the range mentioned below.

Consequently there is no voltage selector in the rear of the vacuum degasser.

There are two externally accessible fuses, that protect the power supply.

Power Cords

Different power cords are offered as options with the vacuum degasser. The

female end of each of the power cords is identical. It plugs into the

power-input socket at the rear of the vacuum degasser. The male end of each of

the power cords is different and designed to match the wall socket of a

particular country or region.

WARNING To disconnect the instrument from line, unplug the pwer cord. The power supply still

uses some power, even if the instrument is switched off.

WARNING Shock hazard or damage of your instrumentation can result, if the devices are

connected to a line voltage higher than specified.

CAUTION Make sure to have easy access to the power cable of the instrument, in order to

disconnect the instrument from line.

WARNING Never use cables other than the ones supplied by Agilent Technologies to ensure

proper functionality and compliance with safety or EMC regulations.
