maintained through the cabinet and keep the ambient air temperature at the input to the
power supply below 104
°
F (40
°
C). All air passages must be unobstructed. If air filters are
used on the cabinet air input, they should be checked on a regular schedule for dirt and dust
accumulation.
CAUTION
Cabinet doors and panels must not block air vents located on the unit’s front and rear panels,
providing at least 2” of clearance from these vents. A fan located on the rear panel pulls air in
through the vents on the front panel, and exhausts warmer air through the rear vent.
2.4 Mounting the Filament Power Supply Module(s)
Install the FPS module(s) in the vacuum cubicle, within 6 feet of the high-voltage feedthoughs
that supply power to the e-beam gun. To do so, first drill four holes at the installation
location, in the pattern shown in Figure 2-1. Then place the holes in the bottom of the FPS
module over the drilled holes and secure the FPS in place with the hardware provided.
DANGER: HIGH VOLTAGE
Removal of any of the covers on the FPS module can expose personnel to dangerous or lethal
voltages. Particular care should be taken regarding high voltage, which can arc over a
considerable distance. It is not necessary to be in physical contact with a live terminal in order
for an arc to send a lethal high-voltage discharge through a person’s body.

2.5 Grounding Requirements
2.5.1 Facility Low-Impedance Grounding Requirements
Safe, dependable operation of the power supply cannot be ensured unless a good earth
ground is provided for the system and the power supply. This ground must provide a low-
impedance path for radio frequency (RF) as well as direct current (dc) electricity, and it must
not be connected to that of any other system or equipment. Figure 2-2 shows two different
methods of providing the required low-impedance ground on the facility side of the
installation.
