The Main Power Supply Assembly

The main power supply comprises a closed assembly (no on site repair
possibility).
The power supply provides all DC voltages used in the module except for the
voltages supplied by the lamp power supply to the deuterium and tungsten
lamps in the detectors. The line voltage can vary in a range from 100 240 volts
AC ± 10 % and needs no manual setting.

To disconnect the instrument from line, unplug the power cord. The power
supply still uses some power, even if the power switch on the front panel is
turned off.
