Section 2: Installation
Removal of the HVPS top cover 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.
The HVPS is designed to be installed in an indoor laboratory or clean room in which the
immediate environment is controlled to maintain an ambient temperature of 40° C or lower
and a noncondensing humidity level of 10%-90%. Together, the screen covering the front
panel air vent plus the screen sandwiched between the exhaust fan and the rear panel
provides IP40 ingress protection. These screens prevent solid foreign objects larger than 1
mm in diameter from penetrating the outside chassis but do not provide a barrier against
liquids. Both screens must be removed and cleaned whenever the fan airflow drops more than
15% from its original value or every two years, whichever comes first. The power module
does not require any routine maintenance, aside from the cleaning of the screens.
2.3.2 Air Flow Requirements
The inverters have a temperature sensor that will shut down and latch out further operation if
an overtemperature condition should occur. The customer must ensure a free flow of air is
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.
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.

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.
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.
